get a bigger bucket will help your ph problem. then see where go from there.
id say she drinking that amount of nutes with in a few hours it whack the ph out.
depends on the shade you use as well Gavita 1000w claim to do a 6x4 canopy, you will also have to think of how to get rid the heat as 1000 is prob double heat to a 600w
put a circulation pump in there instead an it stopped it, as the foaming in my rez would gather on the sides then turn to slim an i had to keep wiping it clean every day which drove me mad.
have you put a massive pump an air stone in there try slowing the pump down if u can your prob making to...
Happened to me once. With canna zym. U got a lot bubbles in there?
I changed to flooming an it stopped.
Bubbles are fine foam isn't as builds up an will cause you problems.
yeah tea sounds like to much trouble to me i just want something to get the DWC clean as i do have a chiller an water temp is around 18/20c never goes higher
I have 2x 1000w in same line an run them off a 450cfm.
What have to think about is how cool is the air to start with your pulling/pushing throu. As in winter this fan easy does it yet in summer no chance.
says it on the bottles of the base nutrients if u have the ph perfect stuff. If u do u do have problem your lucky ya near the end id say give the whole system a good clean on next rez change, as u shouldn't need to ph there perfect line.
