Green soil?????

Hey! I'm in AZ also, it's fully algae holmes. Gotta block the light! I have the same problem, especially with rock wool.
Cover dem pots with a piece of heavy paper like a cut out from a paper bag that breathes well. I cut out a circle that is an inch or so larger in diameter than the pot. Then, I cut to the center and slide the paper around the stem. Once your plant has a large enough canopy to block the light itself you can remove the cover.
I used to top soil with hydroton to prevent algae and avoid having to till the soil but now I'm too cheap! lol
Don't sweat the algae, cannabis grows too fast to really be affected but it does block oxygen from the roots, so take action bruddah! (Or sister, I guess)

well it could also be something leaching to the surface. i read somewhere about bloodmeal doing something like that. are they inside? i know how dry it is there, you may want to try a humidifier to see if you can keep them from drying so fast. the perlite should help it hold water too. is that soil from sedona? got a lot of red to it.

Yeah it's from Sedona.
