Heat stress? Hermes?

Hi everyone. I could use another set of eyes on this one. I have a new light im testing. Its very similar to the spydrx plus units from fluence. Thats actually part of the reason I'm testing this one which is a iluminar il8. This is taking place in a 4x4x7 tent. The tent has a 4" extraction fan feeding fresh air in from the cold room which maintains a temperature of 63 all year. Although this had been sufficient for the last light this is no longer the case. The tent temp are routinely...

Why did my plants grow so slowly?

i grew 8 Blue Cookies bag seed and it was my first grow. Right now they are halfway through flowering. The only problems I encountered were lots of bugs (esp. caterpillars) eating leaves like crazy. I grew them outside. They were not fed for the first month and a half. Also did not fill soil all the way to top of 3 gal pots. Yet they are still each 1 1/2-3 ft tall with not a lot of nodes. Kind of like an autoflower. What exactly happened? They have very healthy leaves which are all a nice...

Newer grow, NEED SOME HELP!!

So I a friend recently gave me a few clones he had left over. It was late in the season but I figured I’d give it a go. Started in small pots then put them in 3 gal smart pots with a medium of Coco/perlite (coco pearl brand). I have had the plants outside in my field but the cold is creeping fast as the seasons are turning so I’ve been bringing them in at dusk and out in the morning. I had used maxi grow and maxi bloom before so that’s what I went with. Plants were doing awesome until about...

White Leaves

This can be considered an update to this post: https://www.rollitup.org/t/so-many-mistakes.975484/

I'm now seeing some white discoloration on two of my girls. I've read a few forums but wanted some more direct input. I'm fairly certain its from the lights being too close before I backed em off, the plants took off and before I knew it they were touching the bulbs in some places. However the leaves that discolored were not the ones to havw actually touched the bulb. That makes me...

So I have posted on a few other websites to try and get some help with this issue but no one has been able to give me any advice at all so I thought I would try “Rollitup”
This is my first grow and I was looking for a little advice.

Cloning in SOIL

Hey guys,

Im cloning from a 2 week flowering mother plant. I've used soil instead of grow medium and have dipped the clones into rooting formula prior to potting.

15 days later and im quite certain the clones have rooted. Problem is as follows:

Problem 1. Since i use a humidity dome, I've been having issues with fungus or algae (green slime) growing on the soil.

Problem 2. Since the roots are newly forming, the soil stays damp. Thats making problem 1 alot worse. It could also lead to...

Problem with one seedling and not the other in identical conditions has me confused

Anything strange going on here? Both 8 days old, both in the same soil, same light, just water and no nutes yet. Temps constant between 73 & 75. Hard to tell, but they are about 2" or so tall.

Other than the slow height growth, which I was told can be normal with White Widow autoflowers, I'm confused as to why one looks clearly different that the other. One seems to have some sort of problem and the other *seems* ok, but possibly developing the same issue.

Desperately seeking advise on this problem

This problem seems to always occur a couple days after I give my plants an organic feeding of local goat manure and local bat guano.

My guess is that some nutrient causes a lockout which in turn causes a deficiency, I'm also guessing it might be a fungal infection (which I still kinda doubt) stemming from the local bat guano, because plants seem to be just fine when I use the goat manure on its own during veg.

Plants not doing well after transferring to dwc reservoir

I started these seeds a little over 3 weeks ago. This Tuesday I transferred the plants into DIY net cups that I put in a single 10 gal DWC reservoir.

I'm growing a GSC Auto she's on day 19 from sprouting.

PH was a different story. It was between 7 and 8 (using color chart). So I adjusted PH with PH down and topped up the reservoir with...

Can Underfed mimic overwatering?

I have a couple plants in dwc that are drooping and look to be overwatered. I read another thread where someone mentioned that too low ppm (250 and under) can cause drooping that looks similar. This made me think it might be my problem since my ppm is right at 250. Is this too low for a 5 week old plant? It was slow getting going so it’s relatively small (6 nodes) for its age I think.

Could the 1200 watt LEDs be the issue ?

Hey guys,

Having trouble identifying the source of a leaf discoloration / weakness problem.

Problem started way back in week 1 of grow. Yellow streaks on leaves started appearing. (almost like they were brushed yellow).

Leaves were also dry and crispy to the touch. I use a 1200 watt led that i was advised to raise further from the canopy (27" to 37"). That appeared to solve the dryness problem. That also solved the yellow streaking issue on the leaves.

Then a bigger problem popped up:...

Could the 1200 watt LEDs be the issue ?

Young AK47-autos struggling

Hey!
Got some 3-week old AK47-autos that are struggling for some reason. They’re lower leaves are yellowing and getting brown spots. I don’t think it’s nitrogen deficiency as the soil I’ve used is pre-fertilized and it’s only been three weeks. Could there be any other causes? I included some pics
Thanks for any advice!
