Hello I started a BF Pineapple Express 14 days ago she started a little slow but looked heathy till yesterday now 2 of her leaves yellowed/faded a little bit haven't feed her anything but water. Here is the link to my journal she has been well documented in there of everything done till this point

If anyone can help that would be great. I'm thinking she ether is deficient in something maybe or she didn't like when I switched to mh light

To me it looks like the beginning symptoms of a hungry plant. I am a hydro grower though, so my only advise would be to give her some nitrogen. I have heard that soil tends to be hot, but since your lights have been so close, that could be cause for the increase their nutrient demands. It doesn't appear to be a problem yet though, keep an eye on her and if it continues feed her a very light dose of nutrients, and then move on from there.

How do they cotelydons look? The original embryonic seed leaves. I cant see them in the picture. If they are already pale or dying that would be another possible indicator that she is hungry
