Brown/rust spots and yellow leaves at the bottom
Ph0en1xstarted grow question 3h ago
Plant in late veg (soil) is showing spreading brown/rust spots on upper leaves and rapid yellowing on lower leaves. Frist only at one plant and now at the others too. I suspect a pH-induced Cal-Mag lockout. But I always check pH to be around 6,5. What should I do?

hey 👋
If you are using soil, your pH is fine; if you are using coco, lower it a little (6.0 is OK)
At the end of the vegetative stage, you absolutely must start using CalMag, especially since your pots are small.
Add 2 ml/l to your watering water each time. The affected leaves are lost, but the new ones should be healthy.
enjoy ur grow!

Seedling Light-burn or ToxicityHi 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.

In both cases, the first leaves turn yellow at the very bottom. They are to be cut after 60 days. On two plants, red discoloration appear on some branches. Both are higher than in the manufacturer's description. Is everything ok so far?
