Looks more like Brown Slime Algae.
Something I have become more familiar with then I ever cared to. Its a Pain in the butt!
Whats the res temps? Ambient air temps? What nutes? h202 will not fix it, if it is Brown Slime Algae.
Let me know!
Interesting note about the 12/12. I was talking to a friend the other day and I mentioned that when growing outside the plants always showed their sex in the first week of August, well the light definitely isn't 12/12 then, not until closer to the end of September, the Vernal Equinox.
Cannabis plants will show their sex before flowering. They show it when they have reached proper maturity. In the outdoors, plants have plenty of time to reach this point. Indoors, we generally want to start the flowering process sooner (itchy trigger fingers) and we start 12/12 before the sex is known. This triggers the plant, and will force it to show sex. Forcing it sooner, allows you to take out any males, and also helps keep the plant within indoor height/size limits most people want. Outdoors, you tend to have more room, so you want some big ole trees.
When starting a plant early into flowering, the plant will take 2+ weeks to begin flowering. You should continue veg nutes until flowers begin to form (start to see white hairs). If you veg them out until they show pre-flowers and don't start 12/12 until they have reached sexual maturity you will see signs of flowers slightly faster.
Outdoors, the shorter hours is what triggers the flowerings. Not that the lights get exactly 18/6 and then 12/12 but that as light decreases, the plants figure it out (some sooner then others) and begin their flowering process. Indoors, we just like to keep it simple and go 18/6 (or 24/0) to 12/12.
From what I gather anyway.
Just got my outdoor beans lined up. Looks like I will be giving some autoflowers a try and see if I can get a couple harvest out of them. This will be my first attempt with any autoflowers.
