Hi yall, I am having a few issues with my plants. The first is I am seeing this white mold or mildew like substance on my rockwool cubes. Can anyone tell me if it is something I should be concerned about and if so what treatment I should use. I have a bottle of plant therapy and root cleaner but I haven't used them yet.
The second issue as you can see is my plants don't seem to be thriving. The purple stems is my main concern. Maybe a Mg deficiency. I believe I may have had a ph lockout. My ph runoff was 6.9 from the rockwool cubes. I have flushed them with a 1.3 ec 5.8 ph'd nutrient solution. So hopefully that will correct itself in a few days.
I am using ro water with jacks 321 with recharge as beneficials. Growing under 240w samsung leds 3000k
Thank you guys for the help. Cheers
