I would venture to say your PH is killing your plants. I would feed them so ph 5.6 water for a few days with no nutes.
Also water how much your watering them they will wilt with too much AND too little. the air pots will help you a bit now.
Look at all those pretty colors
The water is always corrected to 6.4/6.5 - and I ALWAYS have this problem with the run-off spiralling above 7.00. There's a fair amount of peat in the mix, and this last grow had a sprinkling of Dolomite Lime in it - it's said that Dolomite Lime stablises the ph automatically - but it hasn't worked in this case.
All my grows have had this problem with rising ph. On this last grow, I even repotted, using more peat. So, the current mix is around 2 parts Allmix, Biobizz (soil with added suitable noots), 2 parts peat, and 3 parts perlite.
I've discussed this ph problem on the forum before, but I just can't figure it.
So... there's something going on with those purple tinged leaves... anyone?
On this grow, I'm out of BLOOM ferts, but I'm still feeding Topmax ...
The SToke
Am I doing the right thing, giving them only 6 hours light a day? They seem ok, with very little difference.. maybe it takes a bit longer... but I thought I'd read that the last two weeks (or maybe it was days) spent 6/18 was conducive to the buds... Anyone care to put me right here?
ANY advise is welcome!
