Ca deficiency?

My auto is showing some deficiency, I think it's Ca? Rusty and dried tips on the leaves. Last week she was totally healthy. Feed is the same as last week, 2ml Ca (1-0-0 which has 3% Ca) and 2ml Sensi bloom A/B (5-4-8 which has 2% Ca). Right now I bumped Ca to 3ml and base nute is the same at 2ml.

Spots and yellow leaves

Hey guys,

My plants are in week 5 veg. I have some yellowing and brown spots showing up on some of the lower fan leaves. I noticed them last week but didn’t think anything of it. This week it seems to be getting worse.

Last week I added a little too much CalMag about .4EC so I added water to the res to bring it down.

Feed this week CalMag at .3EC, Sensi Coco A&B at .8EC and then b52, voodoo, root exc, great white and z7

What do you think ?

hi guys, had a few plants displaying what could be a ph problem or even broad mites ( although they are not shiney or showing damage) just wanted to know if anyone had experienced similar issues. Blue cheese from seed, 40% humidity with temperatures around 26 degrees. Placed under a gavita that is at the top of a mammoth tent designed for gavitas, plants around 3 weeks about 3 are displaying similar issues View attachment 4104482View attachment 4104483 ...
