HOLY FUCK-WAFFLES.
Sometimes a problem is complex like nutrient ratios, light emissions or diseases. Sometimes there simple but hard to diagnose like a bad timer or bad pump. Then there's those problems that unless you are at the right place at the right time with the right mind set.
As I have said, my plants have been suffering. My wife and I have been panicking trying to figure out whats wrong. We have tried lots but we could never agree on what the problems was. Burn? Deficiency? we agreed it was nutrient based. I have even been entertaining that a bad batch of B52 might be possible (the only bottle freshly opened during this grow). we tried nitrogen, potassium, flushes and the plants physical look never changed.
So this morning I had that right place right time moment. I think.
Algae plugs.
I can't take pics right now, as I discovered the problem about 10 minutes before lights out but this pic shows my connections from hard pipe to the bucket. Clear vinyl tubing.
I had noticed they were green but never once considered they might be blocked until today. I pulled a plant and stuck a piece of wire and fished out a gelatinous green plug of algae that if not completely blocking the passage at least blocking the vast majority of the flow. I have a modified shop vac I use when i flush the system to suck out the lines as well as possible so i pulled another plant and used it to suck out another plug. Then the lights went out.
So this eve at the very least all those plugs are getting sucked out. We plan on pulling all the plants out of the room and "cleaning" the roots in multiple buckets of water. We fear they are either sitting wet or dry, either way this rinse will help. While they are out I'm going to try to replace as many of the clear lines with opaque hose as I can. Lightly bleach the system, and flush the shit out of it, clean the floor and put it all back together in under 2 hours.
Does anyone think the addition of Piranha would help? This issue has been going on for probably about 3 weeks and It seems growth has stalled. I was thinking it would possibly help the roots.....
Tonight I will try to take some pics of the issue and the fix.
