Yellow parts of leaves.

started grow question 6y ago
Anyone can suggest what kind of problem is on the photo - brighter inner parts of leaves. My idea would be that it needs more Magnesium?

Yep I would say either CalMag deficiency or the light distance is actually too short. The first proposition seems to be the senser one

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)

Nute burn other symptoms. Is this a case of overwatering?
Hey peeps, One of my plants (start of week 5) Started with burnt tips due to nute burn which I've taken steps to halt. Lower leaves started yellowing and drooping, but now a few newer leaves started showing yellowing as well. Is this overwatering + nute burn or is there more?

My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

Light streets? Or nutrient burn?
Hey, could this be stress from the lights? It starts at the top and barely shows at the bottom. The leaves are turning yellow from the tips towards the center. Especially at the top. It's under a 200w lamp.
