Strange leaf shape, who has encountered this and what came out as a result?
1. Am I right that it was just overwatering? 2. Who has experienced the same thing? 3. What are the chances of growing a healthy plant? I appreciate all the responses, this is very important to me, thank you!

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?

Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

Cal-mag deficiency?
Hi guys, I think it's magnesium deficiency (early flowering). I have also noticed a few small burnt spots on the leaves. Is this time for cal-mag? Or am I reading this wrong?

Organic peat control
I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Raise PH of soil? Is run off actuate reading of soil PH? One of my plants might be getting sick, I need a fix for this ASAP!
So quick question... how would I go about raising PH of my soil. I just took a reading about 5 mins ago from my runoff and it was like 5.8!?! It’s never been 5.8, and I do have a little issue with 3 of my fan leaves on one plant. No soil PH meter. Just flushed them 5 days ago...

Yellowing plant
Why is my plant yellow? I thought nitrogen or magnesium or PH. But i tested everything and it is still yellow. I tried flushing and using no nutrients but didnt help. PH is good, tried giving extra nitrogen and magnesium. What else can it be?

Beginning of Week 2 - Yellowing? Over/UnderFeeding?
Are these first leaves showing some yellowing or is this a normal shade for leaves at this point. Just wondering if I might have overfed the plants, or even the opposite. If anyone was able to share what they think it would be extremely appreciated.

PH drops every 4 days
I'm losing PH control 4-5 days after feed. PPM drops to 200-300 and PH drops under 5. I flush the res and add new solution every 5 days because this is what works to stabilize ph. It can hold ph for 4 days before I lose it again. You think I'm under feeding?
