First thing anyone will ask you. Whats the PH at. Ph in the wrong zone will cause certain nutrients to not be taken in by the plant, thus showing signs of deficiency.

Nitrogen Deficiency?
Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

Overwatered - Should i start over?
Heavily overwatered about a week ago. They never really recovered. I fed them some cal mag a few days ago and they perked up a little. Poor aeration in the soil. Last picture is a comparison with my 3 week old blue dream/gorilla cookies. Should i just throw these away and restart

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Yellow leaves at bottom. New growth good. How she looking?
Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.

Should I cut off yellow leaves?
Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)
My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays. Res/Tray@ 6.0PH/653PPM. Coco slurry @6PH/500PPM

Seedling Light-burn or Toxicity
Hi growers! Is this Light Burn, or nutrient toxicity from nutrient dense soil? 2 Mars Hydro TS600 lights at 27" from seedling. PH 6.3 misting soil - RH is 75-80%. - Temp is 77F No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
