Ok after some early problems with my hydrosystem I decided to make the move to coco

pretty good move.. everything is progressing again.
(1)400w MH (4)125w 6500ks
24 un sexed plants and 2 on the side that aren't really ready for all that light.. think I killed one lol its just bag seed I got bored and germed so I could test some things

just trying to see what to not do again ....
Super ghetto rigged for effectiveness A+
Using a mix of Canna Coco A&B,Liquid Karma,Diamond Nectar,Hygrozyme,SM-90 at 300ppm.. they like it /shrug gotta listen to the kids.. I had a mix up on a few things.. mainly watering heh even with trying to not overwater .. I overwatered a tad bit :P and a light height problem.. burnt a couple with my T5s being to close...
They're doing great now.. Less is more

They like these Botanicare Cocogro blocks alot to.
Height avg is 2inches + so i'm getting ready to switch them to 18/6 and adding some red spectrum... to let them get ready for flowering.. going to switch when they are alittle over 6-8inches tall. Can do 12inches if 10-12plants will fit the Area.. any advice on this??
