-overfert is not good....gotta get your foot off the nute pedal man lol...I liked flushing for 24 hours weekly ... I know it's unpopular...but I had some nice plants doin' that...when I did-VT- I think your right there about the environment and lighting, just rmember im cheating using the superbud hhehe... i cant say im overall happy with this grow..had some problems with overferting..flooding...as you might see some alge on the floor, went in at lights aout, bumped one of the lids so the drippers were dripping onto the floor err...lol...just not happy with the recirc in general...or the structures of the plants. cant wait (allreadly lol) to finsh this lot and renovate ,going back to whats allways worked for me,,,plain and simple DWC no raised buckets etc..also mixed lighting..the 600's horizontal (in my AC hoods) and the 1k vertical on the mover..also going back to hydrotron, im convinced the lava rocks not as efficient..takes the plants ALOT longer to reach down into the buckets..and they hold more moisture IMO.which isnt good for a 24/7 top feed recirc..
