I believe you need to raise your lights or you could try to dim it this looks like light burn. Also try feeding a little bit.

It looks like a cal mag issue. If your growing in coco, calmag is required. One downside to coco is it absorbs cal mag. Plus coco is to stay saturated with a ph of 5.8 in vegging. That is a 5.8 run off. No dry time in coco. Good luck and happy growing 🌱

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Seedling leaves are discolored and starting to curlNot sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!Leaves. Curl up

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Leaf curling cause - Humidity, nutrient or overwateringHey fellow growmies,
Leaves are curling and fading which I have seen in other grows for this strain.
Do you know what might be causing this and how best to remediate?
Humidity has been high recently ie above 60% for large periods
Watering has been consistent
Nutrients reduced

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.
