You have nute burn. Test runoff and flush if runoff is hot.

Is this possible nutrient burn?
Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Is the browning caused by nutrient burn or symptoms of something else? I had previously backed off, but want to know if I'm missing something. Most of the stems are red for leaves as well as petrioles. My runoff is around 900 each time @6.1. Only one plant of 2 has this.

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)
This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.

Week 6. First pic. She has preflowers and started the stretch period. All new leaves have pale tips, just the new ones on each branch. I'm using atami Terra leaves, 4ml/l 850 ppm pH 6.2 Is it too much? They don't look burned is more a deficiency maybe

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Discolored leaf edges with few burnt tips Deficancy? Nuit. Burn?
1st auto grow. Feeding DTE organics. Basement blueberries is my diary name if you want to look over the entire grow. 1 pheno has discolored leaf edges and a few burnt tips. Is this magnesium or potassium deficiency? Or did I mis-diagnose this and it's something else?

Grower question
Any 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.

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?

Is this light burn?
I am pretty sure it is led light scald but just thought id try to verify. I have a new 650w Hortibloom light bar and have been running it between 400w and 650w at the top of the tent. I'm guessing 650w, even at the top... is too much? They are in soil, and I'm using gaia green
