Any solution on how to fix this are welcome, thanks for the response

LetsGrowSomeanswered grow question 2 years ago
I'm a beginner so take it for what it's worth. Saw no one has answered you yet. Looking at some charts, appears there could be an excess in phosphorus. It would cause magnesium/calcium deficiency. Was trying to see what nutes your giving. If it's the one with veg and bloom, May be too much bloom causing excess phosphorus. That would be a flush, wait for top 2 inches to dry out and then back to normal nutes with maybe a little less bloom at this stage. Again I'm new and just taking a stab at it. Definitely see if someone with experience has a solution. Happy growing and good luck!

Leaf fade vs. deficiencyHey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.Buds. Not fattening

Spotted crisp leavesWhat'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.Leaves. Edges burnt

Fine-Tuning Nitrogen Understanding (Deficiency or Toxicity) -- Suspected deficiency, so how do I adjust Fox Farm nutes? Increase ALL 3 nutes to 3/4 dose?Initial inter-vein yellowing, followed by whole leaf yellowing. Minor leaf stem reddening. Older growth. Normal for flower stage (I believe), but too early for normal and rapid discoloration (week 6). This makes me believe it's a nitrogen deficiency, amplified by SLIGHT overwaterLeaves. Color - Yellow
