as you can see on some picture some leaves have burnt edges, others are 80% yellow-ish and few have yellow dots. I thought that I gave too much nutrients so I've been giving her only straight water for 8 days and more power light for 4 days. No improvement it's worse now. PleaseWeek 11

Why are these leaves browning?What is the cause of the leaves browning on the shorter GG4 plants?
They are closest to the fan but it’s pointed away and set to the lower setting.
PPFD over those leaves ranges from 800-1100, while the ppfd over the unaffected Lime OG is 1300.

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges.
Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem...
Or Potassium deficit? Or any other secondary nutrient deficit?

Brown tips and edges, but not on all plants.2 out of 3 Kratky plants are showing some crispy brown at the tips and edges.
Would I be seeing nute burn at 550-750 ppm? Why only 2 plants? Why only the Kratky but not the DWC? (Same strain.)
(I am actually using GH FloraDuo A and B)
Thank you!
