Leaves getting light green to yellow
GRow_M8sanswered grow question 5 years ago
Hey m8 nice work 🙂❗
You ll need a cal/mag nut solution if you haven't already.
Use it with next watering and see how it goes.

hi @maxwell , due to the yellowing of between the veins of the leaves and the dry tips curling upwards, it seems to me a lack of magnesium. you have to apply some source of magnesium, calmag or epsom salt. if the problem persists, you will have to flush your substrate to clean the accumulation of mineral salts and apply calmag . good luck mate 👍

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…Leaves. Color - Yellow

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).

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.Week 1
