Im into the first week of flowering,I switched to 12/12 and started having problems.leaves had little red and brown spots on them that progressivly got worse,within 48 hours leaves started dying off,some turning crispy and falling off.tops are healthy,production is good. I've checked soil ph and runoff ph. evrything is good there but n-is low p-is low k-is a little high.i have increased my bloom juice to try and compensate any advise will help!!

Do those grow bags allow for any drainage? It could be any number of issues not necessarily related to pH, but it's difficult to tell what might be causing the problems without knowing more about your grow... you'll get more tailored answers if you fill out the troubleshooting form (http://boards.cannabis.com/plant-problems/127058-troubleshooting-form-yay-you-know-you-wanted-one.html) first.

Thanks for the reply,but I ran it down as a calcium deff. so I added some lime and increased the nutes,with some pruning and some praying all is well.
Im now in the second week of flowering production is increasing!!

a calcium deff was my first guess as well and those are the 2 most obvious signs...........but u would have showed some symptoms during veg as well if u are using the same water as u are in flowering.

just a few spots no the leaves thats it
