Where do I get Superthrive? Can I get it in Canada? Home depot, nurseries, or hydro store?

They got 1/8 strength feeding and seem to be doing well this morning.
I will trim the brown off the leaves today and will post some pics tonight.

They are going into flower on Wed next week and I have a pot question....

Will a 6" pot last the 7 weeks flower cycle without becoming rootbound? Keep in mind there is very little veg time. I think they will but I need the reassurance as i don't want to have to transplant to 8" 4 weeks in. Plus I won't have enough room if I move to 8" or larger.

Anyway, i appreciate the comments and support of the group. Thanks.
blink_inc Reviewed by blink_inc on . 50 Clones in Rockwool - Soil Grow Well, here they are. 50 clipped, 50 rooted. They look a little defficient in N. We'll work on that soon. Will be SOG with this batch to compare against ScRog which was done last time. Temps are 74. RH is 65%. 18/6 for the next 2 weeks. Under Sunblaster Flouros. Moving to under 2 x 400HPS in 2 weeks right to 12/12. Rating: 5
