Plants are looks great .. 2 of the plants have huge colas already and getting bigger and fatter everyday.. I'm hoping the other 2 catch up ..lol Been having some issues while mixing my nutrients in my resivor.. Got alot of great info from other growers on GD network and was able to resolve my issues... Turns out the rhino skin was causing all the issues ... Since getting some help I havent had any issue with the nutrients mixture.. I also cut down on how much additives I add each feed.. Also notice my stems are purple... from what I remember they were always purple since I got the clones ... maybe genetics or sulfur deficiency or something ... anyways to far into the week to be worried about that , although this maybe why 2 of the plants have slower bud production..
