These are filling out very well - this week I trimmed under the screen. I'm noticing some spots on leaves so I'm upping the TDS to 1100 and foliar fed using foop. I'll veg for another week or so and then go to flower.
@BigDaddyK, It's all good - I'm hanging it up with this RDWC, though. I'm growing in a garage in the desert and to keep the water temp low I'll have blast the A/C. I'm buying more autopots and packing this system up until December!
