My current crop seems somewhat unhappy, and I'm unsure what's wrong. I'm growing in a 4x8 sunhut silver, 2k HPS, using bio-bizz lightmix cut with perlite, feeding with House and garden per the soil A/B chart. My tent has good ventilation, and my temps are pretty good; high 70's lights on, mid 60's lights off. I'm at about week 3 of veg(18/6). The plants just seem a little "limp", not the nice perkiness one would expect from happy plants. I gave them a slight cal/mag deficiency early on(forgot to add cal/mag for the first few waterings), but that's been corrected. I transplanted from 1 to 5 gal containers this tuesday. At the time the plants were a little dry(before transplant), but the rootballs appeared to be vigorous and healthy. Now the plants just continue to look limp. Here's a few pics of the situation...
