Hello new grower here I have a 12 site autopot system we are on week 3 and I just turned on my system 3 days ago so it has been over 5 days since top feeding I am in a 50/50 coco clay pebble mix with an inch or so clay pebbles at the bottom I’m using gh flora series with diamond nectar bio root cal mag and armor si ph 5.8 ppm between 800-1100 and ec of 1.1-1.2 I just noticed I’m starting to have what I believe is algae and possibly mold starting to grow on the top layer of my pots can someone please help shed some light on this and any advise on what I should do my tent has a constant exhaust fan running with a box fan to circulate the air and a humidifier keeping the RH between 45-60% and my temps are between 72-78f my plants appear to be healthy but I’m not 100% sure. since I’ve turned the system on they have exploded with growth but I’m worried I have fungus or mold growing

Looks like algae to me. Light,damp= algae growth. Cutting squares of panda plastic with a slice in it to go around plant and lay on top of pots will help. No light kills algae. Three thing algae needs, light,damp area and nitrogen to eat.

It looks like you have algae forming from water when top feeding possibly, CO listed a good treatment ^

Is the white stuff algae as well? Should I scoop off the top layer and add fresh coco?

I would think a little spray of hydrogen peroxide would take that right out.

However, unless its just your lighting casting a yellow hue over everything its looks from the pictures to be too light green.
Do you add any silica?

white stuff is salt deposits but you can try adding some fresh on top and see if without the topfeed it stays clean

For the first round of nutes using the res I added armor si which is what they are being fed now but it’s my first round using it and I thought they looked too like green what can I do to bring them to that dark healthy green
