I'll be switching from referencing the calendar dates to days from seed now.
Day 21- 4-6oz ea of HALF strength veg
Started running full spectrum approximately 25,000 lux at canopy
Day 22- determined that they're showing mild signs of nutrient deficiency because they're in a soilless medium and I've been only moldy feeding. I noticed light spots on the leaves and tip burn. Coupled with dark foliage and short growth, I decided to add calmag to their water today. 1/2 strength. 6oz ea.
Day 23- 2 pH meters are reading at/above 7 but under 8. 4oz ea plain water
Day 24- 8oz ea HALF strength veg and I introduced a natural co2 emitting bag of weird crap from Amazon.
Day 25- light water
Day 26- 8oz water each NOTICED FIRST FLOWER and began LST again.
Removed one fan leaf each and a couple fingers
Day 27- 16oz each FULL strength veg
Day 28- no h20
I can tell air quality for me has decreased since adding the co2. I don't have a meter but I when I pull my head out and zip it closed, the air outside the tent is waaaaayyy easier to breathe. And I'm seeing good growth since I got it.
I've been being really shy on fertilizer but decided to kick it up a notch to full strength as long as they react well. Maybe I'll go half or ¾ now and then.
