Ok ill dump and do fresh water for a few days.

I have noticed that the PH has been going up a lot in the last few days. Like .5 min in a 24 hour period. Any ideas why that could be.

Thanks
growman Reviewed by growman on . Major problem Hey guys, Im into my second week on a hydro system and i am having a problem with the plants. Yellowing of the leaves on the tips and on some it looks like a nut burn through the entire leaf. This has just happened in the last few days. I am running a ph of around 6 which has been fluctuating .2 either way. I was running a EC of 1.3 but have since done a dump and its sitting at 1.1 now. Attached is a copy of pics Rating: 5
