Thanks for suggesting the ph...all I can say is that my ph levels have read 5.8 - 6.0 max for the last two weeks consistently, which is why I thought it was nuteburn...just noticed that some roots actually made it into the NFT reservoir...while this happened last time I had a (happily trouble-free, wildly successful) micro-grow, it didn't happen until they were way into flowering mode...any thoughts on roots in the tanks?
best,

jashbery Reviewed by jashbery on . Oy vey! Nutrient burn? This is my third hydro grow, and so far it's been a bit problematic. Some background...these are two feminized 'Oasis' plants, and I've been upping nutes over the past few days (using ec meter to measure levels). Yesterday I bumped it up to .9 from .7, and this morning I found one plant all shrivelled up and the other one, while looking OK, with yellow spotting on the leaves. I threw two litres of fresh water in there, adjusted PH, and brought nute levels down to .7. Should I simply wait and Rating: 5
