Rust spots on leaves, second grow and need some confirmation.
JebusHealsstarted grow question 2mo ago
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

It looks more like an excess, nitrogen perhaps; I don't see anything alarming yet. Excess lime/mag can also create stains, with respect to washing..I would choose to give them a few waterings with only water, adequate pH, and continue with the waterings with fertilizers with lower doses. 🙂

Phosphorus? Potassium? CalMag? What is going on here?So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Spots on yellowing leavesBrown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red.
It starts low and eventually ends affecting buds too so I chop.

Nitrogen toxicity? Deficiency? Something else? Stumped!I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.

Yellowing a bit too soonDuring the second week, leaves started to look a little bit yellow. The first true leaves yellowed way too soon. I'm guessing lack of nutrients. It never showed signs of drought or overwater stress. Your thoughts?
