If its just the lower leaves it may be from getting them wet when watering.

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!9mo ago

Identifying the cause of stressDoes anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?Week 7

Lime green/yellow plantsOk so my OG Ladies are looking pretty lime green/yellow.
I noticed when I mixed my nutes I think I mixed up the a and b bottles I also don’t really check PH, relying on microbes to buffer. I checked it and it’s high. Iv fixed the res mix and upped the dose. It’s been 24h ish…Week 8

Leaf DiagnosisCould someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?Week 4

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.Leaves. Color - Yellow

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy.
Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator.
It seems to be curling in as well.Week 2
