Also I wanted to ask about the sm90 and your res water. I was dealing with the same problems as you about the same time. Some high temp issues bloomed the dreaded algae that slimes crap up and grows the brown crap on your roots that suffocates them and lets things like pythium and fusarium take over.
I changed out all my feed lines, and cleaned everything real good, replaced all my filters, and installed a uv light before ro filter. got the water temps steady around 64f. So im dialed in pretty good, and thought I noticed a foul smell in one of the res's. The only thing I noticed that had anything on it was the ph probe tips. they had the white cotton slimy starting growth on the wicks. I noticed the black mold type material sticking to the silica barrier for the ph probe wont come clean. I feel that's the last growth problem ive had to replace. So I wanted to ask how you were liking the sm90? Ive used it in the past and thought that it left an oily residue on everything that I wasn't fond of? Is that your experience? I know you mentioned you clean your res every 5 days. Are you still doing that? And is the sm90 a mess to clean up when you do the res clean? I have been using bleach to keep the res sterile, but im not real fond of that option either since it is basic, and raises ph. Plus the biggest problem with chlorine is it dissipates so fast. At least with the sm90 route, its effectiveness should last the duration of the nutrient solution. Honestly id just like to go clean, and wipe down my res's once a weak. that's what im starting with after I clean and change my probes today. Just wanted to pick your brain a little on the sm90 usage.
Yes I live in a rain belt. The weather here is so weird. 10 miles down the road it hardly ever rains. I live up the mountain and it's a rain forest. Especially now. Our weather patterns have changed here big time. All my grower friends are experiencing the same things here. Only a few that live in certain areas are still doing well with outdoor. Even my tried-and-true strains that I've been growing for 7 8 years here have problems. I can get my plants up to about two or three feet during veg and have no symptoms of blight or anything and that's with spraying and paying very close attention, but once they go out to flower there's no stopping the blight and this purple stuff that comes on the new growth soptoria. So I have discontinued my outdoor grow I got another CMH lamp and I'm firing up the closet in this girl room and that's going to be my Greenhouse LOL. I wasn't getting much yield out of 30 gallon pots. There's just no sun anymore. It rains every single day and pretty much all throughout the night. Not many strains can grow in a hundred percent humidity in hardly any sunlight.
I totally get what you mean about the brown slime. When your res get stinky grimy it's kind of a factor of what kind of nutrients you're putting in. I noticed when I was using floranova the floralicious plus would make my res stink faster than normal.. then I started sm90 and that went away.
I have never noticed any kind of slime or residue left over from sm 90. I use 5 mill a gallon in every rez change. If I don't my rez gets funky faster. Even at 64 degrees. So I'm betting if you ditch the beach and start on the 5 mill a gallon you will be pleased.
Yes I clean my res every 5 days but everyday I top off. I only have a 50 Rez out outside so whatever the plants drink that night I look at the marks on the side of the rez and fill it back up with RO water and then just add whatever nutrients per gallon that I added back in...
Basically I love my res now that I use sm-90.. it's just a dream to clean and it stays nice and fresh, it's really night and day bro. I will never not use as a 90 ever.
If your temps are at 64 and you're still getting some stink you're probably adding some organic contents something really dense that likes to breed and live.? Sm-90 at 5 Mills of gallon will make your rez nice and happy.. give it a shot.
