yea looks fine shit is kinda dark, check everything, pH, temps, nutes, whatever, if you find no problems, then its just the strain. really, as long as their is growth, your ok
Its been cold in the UK this last week! I think its a heat issue as they are right under the lamp , perhaps its the range in extremities making it purp out. I was worried they were seeding or something. This bud was removed as it was getting toasted, smokes up nice and it let the light out better, so yeah it is an odd looking bud.
