friends, help me figure out what's going on!?((the little sprout had symptoms earlier! the bigger one just started to dry the tips today!(
friends, help me identify the symptoms!?I don't understand that this is a nutrient burn? or the light or something else!? A light of 100 watts hanging at a distance of 27 inches! or is there not enough humidity?two identical sprouts with the same solution of 250-280 ppm !!

Yellowing of upper leaves normal or problematic?
I'm in the final stage of the grow, pistils are starting to get orange. Today I noticed some upper leaves tuned yellow / are dying. The leaves in the middle seem fine. It's this normal or problematic? Thanks in advance for helping me out.

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.

Leaf Yellowing?
What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?

CalMag or something else?
Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?
