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.

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?

Discoloration and burnt edges on leaves
Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

The top leaves are showing burnt tips but only on the top. Is this because its too close to the light or is this because of nutrients?

Nute Burn or Calcium deficiency?
Hey, I’ve just joined the website and already looking forward to making a dairy for my current auto grow. I have 1 auto, Barney's Tangerine Dream that Ive trained to fill my tent. I seem to be experiencing possible nute burn, would anyone agree? Or is it a calcium deficiency?

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅
