Cloudy grow

Hi Y'all! Update; the plants (except the new hindu kush) will be one month old on the 20th! I planted them on May 20th. Very excited!! I've defoliated a bit of the hindu kush and some of the smaller branches on both the Skywalker and GSC as well. Ever since, the preflowers have been growing something crazy! I thought after looking at Skywalker, realizing it's a photoperiod instead of an Auto like the rest, I topped it. The next day while doing LST stretches on the top branches, I accidentally pulled a branch off :( One of the preflowers migrated and is growing in its place! And interesting enough, the node that I topped on it started sprouting a little more so I think it's going to regrow where it got topped. Very cool! In an effort to keep the second hindu kush short and even bushier, I LST'd the main branch down pretty severely. It's reacted well though! Growing well. This hindu Kush from fastbuds has such weird mutations for the first set of leaves. Lol. Anyway, I'm having a bit of a reaction out of the leaves (specifically two leaves on each plant). I thought it was nute burn, so I flushed for two days with straight water. Still progressed, so I'm thinking it looks like a Magnesium deficiency but i'm not 100% sure. Gonna buy some Cal-Mag and introduce that into the nutrient uptake just to be safe! Put the plants on a 20 hour light cycle again. They've responded well!
