Got another bean in fresh rockwool and cleaned out the NFT system. Refilled with tap water which had been left to warm up to room temp, a wee cap of grow nutes to get the EC to about 0.5 and then pH down to get to about 5.6.
Initially I don't make up a full 20 litre res as for the first couple of weeks it should just be a case of adding water to keep the pH up to counteract the effect of acidic root secretions (handy when the roots are trying to get through soil but vestigial in hydro and can make pH swing low). Then after a couple of weeks I'll be looking for pH to start going up between top ups which I take as a cue to add more nutes to keep pH in range. By week 4 I hope to have nutes at over 1.5 (pretty much full strength) and be switching to bloom nutes.
Anyway, one of the side branches on the 50 day old one....
Light off pic with ringflash......No chance I can get them to available light to photograph before harvesting but once I get them prettier I can put more effort into the photography.
I'll get my better macro lens up here for some closer pics in the meantime.
