Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Why are my leaves turning this color?I scratched in 1 TBSP of Down to Earth AP (4-6-2) 5days ago with 2L of pH’d water (6.5). I believe I over watered as the leaves got droopy and then all of a sudden had a bunch of gnats. Killed them, soil is drying but now pale leaves and brown spotsWeek 6

Is this a Deficiency or Normal Flowering.Flower 4 weeks. I have noticed thru flower approx 5 - 10 leaves/week which eventually brown, shrivel up, and fall off. Leaves seem dark and the stems are slightly reddish purple but potassium test on soil shows high potassium. Some burnt tips and claw down on upper leaves. PH6.05y ago

Maybe nutrient burn or?My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back upWeek 4

Auto OG dying off? 9 weekAs You may notice- problem with OG-1. I burned her once, was a mistake,when suddenly she demanded more watter unnecspectedly and i gave her higher dose of everything,instead of watter. Before was perfect plant (if im not mistaken). Wattering- once is light in the hands,by liftingWeek 9

CalMag or something else?Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary.
Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse.
Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?Week 3

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).Leaves. Curl up
