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 👍

PH Fluctuations and/or Nutrient Issues?I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Organic peat controlI think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Burnt, should I throw it and start from zero?I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12? The light is farther now but maybe I can do something else than put away my lights.. my current schedule is 18/6 and the plant is around 45-50 days old

Yellowing leafs.Hello guys, my plant is now on the final weeks of flowering, buds are getting bigger and the leafs are getting yellow pretty fast. It's this last thing that scares me a little, I know it's completely normal due to flowering but I wanted to ear your thoughts about it. Thank you 😊

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?
