@Budzbuddha Wish I seen your "FFOF made simple" thread before starting my grow....
I grew in soil 20+ years ago, but I'm on my first run since. Growing 2 Roc Bud Inc. freebies, unknown strains. I planted the seeds in 3 gal fabric pots with FFOF, but I scooped out the top center (around the size of a softball) and filled that with seed starter mix. Growers Choice e-680 LED currently dimmed to 60%. I'm using RO water (but may switch to tap) to which I add 5ml per gallon each of CalMag and Silica Blast, ph'd to 6.5. My 2 plants are 11 days old since the sprouts broke the surface.
This morning, before the lights went out, I noticed for the first time that leaf stems are turning purple. And this afternoon, when the lights came back on, I could tell the purple color has started progressing up into the main leaf vein. So my question: is this problematic, and if so, what am I doing wrong? I'm not seeing any curling, drooping, spotting, etc. Pic from 20 minutes ago. I commented you in because in your thread you mentioned you aren't getting purple stems anymore, so would appreciate knowing the cause, if it isn't just genetics.
First post here I believe, so thank you!
