I have algae. I have put in an intake fan to lower humidity - it worked. I may have this problem as I overfeed - that is I use all the nutrients I've mixed and was getting up to 60% run off. I make up 1L per instructions and dilute to reach target ppms, and feed all of that 1.8L twice a day. I'm only going to feed to 20% run off from now on. I'm going to use 6% 20 vols hydrogen peroxide diluted 1/10 and wipe down the pots - is this a bad idea? The plant is very vibrant and healthy looking. Thanks
