The problem in plants when I supplying CO2
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?

At what stage do leaves get darker ? This is confusing
I overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
