Well, I have RO water now, and I have only added very small nutrients still and some calmag+ at about half the recommended level. They're still doing ok, and I'm happy anyway since I havent smoked in a very long time so anything is going to be nice.

The newest growth looks nice and green and I'm watching closely for any spots to form on the newest growth. I am hoping that the rusty spots were a problem related to my old hard tap water and will clear up.

If it's some sort of mold or something, then I dont know yet what to do exactly.

It is extremely low humidity in this place until my humidifier arrives. It's only like 28%.. I wont get my MH and HPS system until next week. Hopefully I can nurse them along and flower them and take a clone or two and repeat.
