Hi guys, great site been looking about on here for a while in preperation and for general info. I'm doing my first rdwc after doing 6/7 problem free soil grows. I took some time out and then decided to give the dwc a bash for a change , I'm in the uk so mums the word .
To be honest it's not been a great experience so far really or I'm just expecting too much I'm not sure.
I have 5 20l buckets inside the 2x2x2m tent 1x 20l Rez outside tent ,top fed system.4" air stones in each bucket and substantial air pumps .1x600w hps about 2ft above grow ,6" carbon outlet with 4" inlet, large 12" oscillating fan, temps 65/70 lights off 70/80 lights on. I did a lot of research and spared no cost so far, using canna nutes A+B.
I'm growing ww x bb and I germinated them in 1" rockwool .then after roots showed I inserted them into the 4" cubes and it's been 3 weeks now in the dwc in 6" pots.
5 plants all looking like various states of growth from 2"-6" tall , 2 plants looking small & stunted , various brown/yellow spots on older leaves , one looks droopy etc etc. from day 1 the ph is a rock solid 5.8 once set and tbh never moves all week as we speak the ppm is around 550 again never moves really , tbh I don't rarely have to do much . And this is all buckets all perfect spot on and checked twice a day . I've flushed twice also . The roots are amazing on 4/5 , the other 1 not so good like 2/3 long roots in the water. They are pearly white in colour also.i feel like I'm doing everything by the book but the results are very hit and miss considering they are all in the same medium.
These are problems I've been fighting with since week one: leaf claw/deformation , yellow spots on older/lower fan leaves, lower leaves browning, curling/drooping down like it's been over watered, stunted growth.
Now I'm at the conclusion that maybe 550 ppm may be to much to soon and causing a lockout of some sort , nitrogen toxicity possibly , I just don't no I'm stabbing in the dark really , trial n error n all that. But was thinking of dumping the whole water and filling with ph'd plain water for a few days and go from there , so just wondered if anyone else can see something I'm missing , any ideas appreciated in advance.
