Heisenburg/Mr Bond, please help!!!! (again)
OK so its been awhile since iv been here, had brown algae infect 2 separate undercurrent veg systems about 2 1/2 months ago. Started treating with the tea and had great results, plants rebounded and are healthy as can be in flower. When i filled up the flower systems, i scrubbed the ish out of the veg systems, sterilized the 2 veg systems (i must admit one was cleaned better than the other) and new cuttings were put in. It has been bout 5 weeks now for the new cuts, and i have been treating with maintenance levels (roughly 1 cup per gallon) of the tea since day 1 about 2x a week. 2 weeks ago i had to leave town for a week and no tea was given to them for 7 full days. It seems as if the brown sludge was starting to make a comeback so i have been giving them tons of tea (3x in the last 7 days) and at a higher dosage, like 3-4 gallons of teac for 100 gallons of water. i went in to the room yesterday and 2 plants looked like they were dying, very droopy like they haven't been drinking any water. I freaked out, drained the system to wash out most of the bad stuff, then put new nutes (a&b base, magical, 80ml of root excel, and about 4 gallons of tea. when i went back their today, the sludge is WAY worse since yesterday, and the 2 really sick plants i dont think are gonna make it.... Soooo what to do???
My thoughts are i never really use root excel, so by using it did it make my problem worse? also, i didnt realize until after i was done that by draining the system and starting over with new fresh nutes and tea i am essentially wiping out any establishment of good bennies that have colonized??
part of me wants to give it a few days to see if there is any kind of response from the tea, and the other want to go the physan20 route or a few days to try and kill it, drain and then re-fill with fresh nutes, new batch of tea and i hate to say it but no root excell.
please chime in with your expertise, you both have helped me so much in the past and now i feel like giving up....this algae seems to never go away!!!!!!!
lastly, what would recommend to sterilize the system to prepare the best for next round?
many thanks~!!!!!
