SLH 1ST GROW

Buds are getting bigger. Still haven't got on top of the ph problem. Still keeps climbing and sitting around 7.5ph. Keep lowering it to around 6.2ph and I've changed the nute solution reservoir, but it just keeps going back up. Doesn't actually seem to be having any major effects other than perhaps slowing down growth. Thought i would have been close to harvest by the end of week 12, but its now week 13 and I can see this going to 16 or even 18 weeks at the current growth rate.
