Does this look ok?

It's little over a month since this Pineapple Express #2 auto was germinated. I have it in ffof soil under growers choice 720 roi led. My 1st time growing in about 10 years and 1st time under led lights. Part of the preflowers are turning a dark color almost black. Has anyone ever seen this before? My Temps are 75-83 with humidity 30-55.

Looking good!

The purple bract colouring is just genetic, no issue there. Some strains just produce more anthocyanins (same pigment that makes grapes red, certain cauliflower purple and so on). Just a sign that they will stack some purple bud.

Thanks for the info. The breeder description didn't say anything about color so I was a little worried. I knew colors can be in the genetics but didn't know they could show up this early.
