pH rising uncontrollably please help w/pics

ph can sometimes be a fickle hellcat lol.

sorry to say bro but you got root rot (pythium) been through it and the shit sucks. you can add som h202 35% food grade at 1tsp per gallon of water and it'll help it get some oxygen and help contain the pythium. i recommend on your next grow, clean all your equipment with some physan20 and get some beneficials for your roots to help prevent it from getting root rot again. i'm currently using voodoo juice, pirahnna from AN and root excelurator from house and gardens. it's some expensive shit but it works. here are my roots. good luck bro!!

yes thats what im saying kill the pythium with h202 good for plants anyways and then get some strong pro-biotic life going i use piranha and tarantula in all grows it out competes undesirable pathogens.

I had this EXACT problem a few weeks ago. I was running Iguana juice and Nirvana with some humics and fulvics too. My Ph was at 5.6 -5.7 for about 3 days. then I thought it would be good to add some beneficials to the mix (aquashield) but as soon as I added the stuff my ph jamped to over 7.0 there was no amount of ph down that would make it go lower than 6.5 then it would spring right back up again. I found out that my bottle of Aquashield was the culprit. Idk if it was bad or just crappy but it hasnt done it again. I would use everything else you are using but the aquashield. if you are worried about pythium do wut BR said and add some H202 but not if your using Botanicare nutes (they dont recommend it). If you want to continue using Botanicare I would pick up an enzyme product like sensizym from advanced. it is supposed to prevent /get rid of pythium, and its the only product ive used for this purpose and ive never had root rot, just big healthy roots.
