That's light stress for sure you can tell by the top of the buds too. Just raise the light. 👍🌱

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?

Condensation, CalMag, Nute Splash?
Twice between heavy defoliations the were leaves were so jammed together some leaves would get wet from contact with other leaves. It's the only leaf on the whole plant like this - as of now. Seems like Calmag? Product of sweating? Nute splash? (week 7 photos)

Saw this first day of 12/12
Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

How's the quality?
How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected
