Room is about 83-84 with the lights on at 65-70% RH. Now mid 50% rh
canna coco as medium.

Using Canna 5-8mL of A/B with Botanicare Cal Mag at 3mL/gal. For first 4wks fed VegBloom RO Soft. Feeding around 800ppm.
Fed at 1000ppm, lowered humidity, temp went up to 88 with CO2 burner on at 1500ppm co2... thats when the discoloration & curl started.

Seriously went weird when the CO2 was added. Added it at wk 6.5. These are 11 wk tables

Just started doing this when adding CO2 a few days ago. They were perfect before adding the CO2. Added it via burner.

Doing a pheno hunt with several different strains.
