Thoughts on my problems?

Have two plants here in coco just flipped into flower about a week ago, they hve been showing the problems for about two weeks and thought a minor flush would be my fix but a no go. Bud sites on the plants arnt really growing and also look skinny with a little twisting. No noticable problems within fan leaves. I am using Canna nutes with tap water at about 90 ppm feeding around 500 ppm total of A+B and Rhiztonic with a runoff of about 650 and a ph of 5.8-6.0. Ill post a picture below....

Seedling issues

I don’t grow from seed honestly never have. So maybe I’m making a lot out of nothing but these seedlings don’t look ok to me.

Sprout in coco. 13 days old today. On the left 2 Blueberry on the right 2 GDP. Watered three times since sprouting just enough to get around the seedling wet. Used 1/4 strength nutes the llast watering.

Temps 23c high end 17c low end. RH 34 lights on up to 70 lights off. Growing in a heated garage and can’t really get a heater or humidifier at the moment. So those...

Killing Root Rot

Can it be done? I have a mild case that isn't killing the large plants but is decimating my cuttings. I have heard of using H2O2 but others so it doesn't work which makes sense because root rot is a fungi and spores get into the plant stem.

Is there a way of getting rid of this aside from wiping out the strain? I'm thinking that maybe I can treat a cutting with a fungicide over and over until it becomes a clean mom.

Big Bud #2 Lower fan leaves turning yellow then purple. Anybody seen this before?

The lowest fan leaves on my 35 day old big bud #2 started to yellow and then started to turn purple.
I've researched loads and havn't come across anything that describes this hence why i've made this thread.

I germinated the seeds on 1st april using wet tissure in the airing cuboard, then put them into a small six pot propagator tray.

Yellowing and drying leaves in soil

Hello

First to thank you all for the great info on this site. I have spent hours reading this valuable info.

I have tried growing for 3 years about 5 grows with all similar outcomes.

I have opted for the organic grow with the biobizz range for not needing to check ph and ppm (which in the beginning I did do)

Everything is beautiful until around 4 weeks into veg, where a nitrogen deficiency seems to be always the problem( I assume). Now it hase arrived 3 weeks into flowering, yellowing...

Manganese deficiency???

I recently watered in some epsom salt for these mag hungry og's. Then this top leaf starts looking like this. I know high amounts of mag can make you manganese deficient I've just never actually seen it before. Anyone got any experience here? Also whats a decently fast acting ORGANIC source of manganese? Kelp meal has a good amount but also high in mag so maybe that will perpetuate the problem? Any help is appreciated.

Self Pollination, Are My Plants F*%#ed?

Week 4 flower.
Two days ago while pruning my plants, I found some nanners on a lower region of my plant. Some pollen spilled onto the stripped branch directly underneath the nanners. I removed the affected minor cola that possessed the nanners, wiped the branch with a 1/3 bleach/ 2/3s water solution, and sprayed the area with mighty wash. The pollen didn't get everywhere and didn't really become airborne. None of the surrounding pistils, or any other pistils on any of my plants...

My 2 poor black widow plants have struggled through this grow. They had some root issues and got behind, then force fed for the rest of the grow.
This is week 6 in flower and one of them is already going mostly brown and the other isnt. Is the plant finishing early from stress or are the buds dying?

I am using no till soil that has actually had been used 2 runs but dumped it all out of the pots into a tote.

Crop King clone issues, droopy af

Hello everyone,

I’m having some difficulty on my fifth plant, a Crop King Crown Royale clone from a friend. It started when she was a few weeks into vegetative stage, with some spotting on lower/older growth curling up and falling off. At that time she was under a 400w MH, but I have since moved her to the 4x4 under the 1000w MH.

She has only gotten worse, exhibiting both symptoms of over watering and under at times. I have already done a flush, the runoff from 6.0 pH water is coming out...

I have 3 plants with issues. They are under a 400 watt hps with 2 led lights in the same room. I got a temp guage to check as I noticed it were warm. One day while at work the temp got to 110-120 degrees F. They looked pissed at me.. the plants were a different color than Im used too since inch one.

Slow groth, White widow automatic RQS

Hey there best people in the world. So I have plant (ww automatic RQS) that sprouted in coco 28 days ago, it looks healthy and is producing new growth but compared to my previous grows of the same strain, it's extremely small. Is this normal at day 28? Should I keep it or kill it?

Strange Pest? Can anyone identify this?

I am growing in a coco-perlite mix, and I am in my first week of 12/12 lighting. I just found these strange "scale-like" blobs on the stem of a fan leaf. Is this an insect or insect feces that anyone has seen before? I've attached pictures of the blob at 80x magnification. It seems the larger blob is about 1mm in diameter, and the smaller one is about 0.5mm. When I crushed the larger blob, it seemed it had a hard shell and was filled with white dust of some kind. Please let me know what this...

Plant looks done at 6 weeks

Not sure its really a problem. More trying to figure out why.

Buddy has a crystal gelato pheno from big head seeds that looks done at 6 weeks. This is the second run and it's with others that finish at a normal time.

It starts getting orange hairs at 4 weeks and fully orange by week 6. New growth stops they swell and look done. Trichs look to be a nice blend of clear, milky, and amber. Let it go the full 10 last go around and it didn't seem overdone in anyway. Other pheno took normal time...

Identifying rust mold

Hi! I'm having some yellow/orange/Brown spots on leaves, they also dry out. I think it may be nutrient burn but I was wondering is there a rule of thumb to test for rust mold? For example, will it rub Brown dust on my fingers?

Waterfarm 8pack problems

Hello Everyone, can anyone give advice on this plant? It just started to droop a couple days ago. My set up is a waterfarm 8 pack. My ph is sitting around 5.8 to 6.

Hey all,

Been busy and didn't have the chance to look at the plants for a few days, came back to look at it today and it has odd looking brown spots on some of the leaves. Its pretty sporadic throughout, I can't pinpoint what might be going on, it doesn't seem to be light burn. I'm growing in hydroponics, using the technaflora starter success kit. I've been using this kit for a few years with amazing results, but this is the first time I'm seeing this. From some googling, I see this could...

Brown spots and slight discoloration on leaves, please help.

Leave fingers facing inward?

On two of my plants i have this going on with a couple leaves.
My temps during the day are 70-78 and during the night a little cooler 62-68.
Humidity around 20-30%
I'm in happy frog soil, using a Mars 49 eco about 24 inches away.
Been watering about ever 5th or 6th day using some floralicious plus every other feeding.

Any thoughts? Really not sure if this is even an issure or not.

Unusually pale seedlings in soil!?

Hello Rollitupers,

I have been growing for quite a while now but I have never had that problem before.

I am growing an Afghan strain in a store-bought organic soil.
The temps are between 62f at night and 72 during the day.
The humidity is around 65%.
I have been watering with straight water at a PH of 6.3
The soil is allowed to dry between waterings.

The plants where growing under a 60w LED and they have been under a 600w HPS for the past 24h.

Here is my problem: The seedlings are all...

Is this a calmag def??

Hello to all,

So as you can see I have this issue, with so internet studying it looks like a magnesium deficiency so I have started to give 1ml of calmag in 1lt of water.

I know temps are very high but is it a catalyst for killing a plant?

Shall I keep feeding my plant the recommended dosage of 1ml grow-heaven-activera?

Shall I start adding the organic bio bizz bloom instead of the calmag?


Thank you

Here is the set up
