Your in the beginning stages of nitrogen toxicity. The greyish dark green color on some of your leaves are an indicator. Also could be your ph not sure if u checked ph runoff, i would check that first and dont feed nitrogen see if it gets better

Looking at the pics, it seems to have pretty obvious internal pressure issues, though nutrients can affect that, but yeah...watering/humidity/oxygenation is probably related. Still looks like mainly calcium issue, but water too.

Looks like calcium (mainly) to me. I'd throw some calcium, maybe a bit of sulphur at it. Watering might in some cases exacerbate those issues (like concentrating excess nutrients, making the imbalance more apparent).

Compare leaf temperature to air temperature. Adjust your humidity and/or temperature until you see 2-4 degrees delta. That seedling needs a VPD of .5 but the full flower plant could be pushed up to 1.5. For optimal growth they need very different environments.

Nitrogen toxicity can cause calcium and potassium lockout. it looks that way. adding more calcium to feeding can help. leaf curling down is a sign of N overload.do not feed them N anymore, only bloom nutes and calcium/magnesium supplement.that plant looks like a weak genetic

Might be a little off in a micronutrient like Cal or copper. Might also want to check for thrips.

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.
