It's day 17(Dec9) and my leaves have a strange discoloration. I can't seem to find out the problem. I have uploaded a picture of how it looks in detail Under week3. Only the older leaves have it with the oldest having the most discoloration.

What’s with this Odd growth rate and leaf pattern Stunted growth on 16 day old northern lights auto. 1/3 coco 2/3 fox farms ocean floor. gave it a minor dose of cal mag plus just in case this is a developing deficiency. It has three nodes but it is very small at approximately 1.5-2 inches. The pattern may be genetic?

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

Leaves curling on sides Okay so the leaves are acting weird and kinda curling in on the sides. Like it's heat issue. I think maybe to strong LEDs. Idk. It's only 79°f Light (ESv300) is on lowest setting @32in away. Fed GH flora trio. Only 237ppm. The leaves are also yellowing between veins.

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Any help identifying this leaf issue?Hi everyone, I have a couple of issues popping up on Medea's leaves, and I'm not sure what they are. She's in week three now, and otherwise looks healthy (if growing a little slower than usual). Her last feed (3 days ago) was her first one with a 1/2 dose of the GH trio (0.3ml/L)

Copper colour, brittle dry patches, any idea what this is caused by?Does anyone know what this is caused by? I've had it on several plants in the past, as well. I've looked it up, but nothing seems to fit. I'd appreciate your opinion. It's on a few leaves, which is why I'd like to know. Thanks, I appreciate your help!! 💚

Yellow leaves near the harvest This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)
