White leaf tips Any idea what can cause these white/light yellow leaf tips, mostly on the newest leafs?? Might be light burn, it’s quit a powerful led (niello m-900) or maybe high on nutrients?

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Help identify yellow tips, curled down leaves and spots Yellow tips started appearing on new growth on this plant few days ago, slight clawing downwards. Some brown spots. I thought it was CalMag deficiency and fed them yesterday with CalMag+light nutes.
