Your plant leaves appear healthy. If just the stems are turning purple, most likely cause is from intense light. Nothing to worry about.

My seedling is 9 days old now and growth is extremely slow. The stem is a red colour and the leaves are a slight yellow. This is my first ever grow and I just can’t figure it out. I would be grateful if anyone could give me some advice.

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

New red tint on top of branches caused by night of low humidity or other stress?
This morning I noticed some branches on my young plants had turned reddish on top. Last night the humidifier ran out of water and RH dropped to 40% overnight. Could this just be a stress reaction to that low RH, or sign of a deeper issue?
