Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?
I think you are just a bit overdoing it on your feeds and lighting.
Of course keep your pH in check. Check out my other answer to your question. Hope it helps
