All you had to do was dim it or raise it higher. If not dimmable then distance to reduce intensity is only way to solve it.

Really doesn’t look like light burn to me. Especially running blurples. They are not especially intense. I think you have some feeding / pH issue possibly - if anything.

Burned tips
What's that? Could it be cal/mag deficiency? I don't think that's light burn cause it happens on the lower leaves too. Sometimes I can see even discoloured patches.

Heatlight stress?
Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future? She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients.

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Dear ganja gurus, please have a look at my diary Wk17 D119. I'm thinking nute lockout due to pH always below 5.8. But any other inputs is most welcome. Nute is 50 ppm epsom, 100ppm CaNO3, 100 ppm MKP, and topped with 7-5-16 A/B to 900ppm.

Do you think the yellowish leaves are because of nutrient deficiency, a nutrient burn, or just her fall colors?

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

Dünne und leicht verbrannte Blätter?
One plant has burnt tips on its leaves, and the leaves have generally grown thin. Interestingly, it's now the biggest one. What happened there? All 4 plants were fertilized with the same water.

Bio Grow burn vs Bio Grow boost
Hi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L). She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering? Is the tradeoff worth it? No burn but less growing?

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!

What's wrong with lemon cheese? Is it overfed? Drain showed me 800 ppm and after flawless finish drain became 600ppm. Or is it my tap water (300-400ppm WITH FILTER)? Should i get reverse osmosis?
