Depends a lot on the strain I've noticed. Could also have to do with the fact I suck at cloning still. My remedy, sour tsunami #3 and c99 that I got from a buddy are all doing great. My special kush clones that I took are finally shaping up, but my ice, g13, pineapple chunk and HH are insanely slow. Not dying, but certainly aren't taking off.
Like I said though, just did the MIR/feed for the first time with them, we'll see how that goes. I was a little more liberal on the feeding with the stronger girls (half dose), only a quarter on the smaller girls.
Oh yeah, my JTRxJHxPurpleUrkle seedling is doing well. The SNSW not so much though. Lol, like I don't think she's gonna make it. Both seedlings were really young still when I had to treat all the girls for PM. In hind sight i should have just let them keep going and treat them a week or so later, but I kinda panicked. No sign of PM since though
