Slight browning of upper mature leaves

Mid week 8 just noticed this color change on the ends of a few fan leaves near the top. It is only noticable on the upper most 4 mature fan leaves. Nothing on the new growth. Nothing on any lower leaves. Any ideas?

Hi @T3METRO The plant seems to me healthy in general, good with nitrogen. It seems to me some chlorosis because the plant is still stretching at this stage. But it may be the beginning of a slight lack of magnesium or calcium, better to prevent and apply a larger dose of calmag. at this stage magnesium and calcium are never too much. good luck mate 👍

Hey m8, The girl looks like a beast, she maybe needs some more calimagic in her feed. Eating Phosphorus like crazy too at this point. Good luck
