Last week I realized that topping off the rez with full strength nutrient water had upped my ppms to 2000, and Ph to almost 7
I mixed a fresh batch of 10ml and saw ppms in the 1700 range, so I watered it down to 1200, 8 ml/gal is just an estimate this week unfortunately.
I added 2.5 ml/gal big bud day 1 week 3 afternoon, Ppms should coming in at 1300
I finally got an accurate height measurement, and given the plant distance decided to turn the light power down to 60%, which should be around 120-130 watts, which is plenty for a 2x2
Did a water change week 3 day 1, used a transfer pump and it was fairly easy, just took a while
More pistils are starting to show up now
I've decided to start measuring ppm/ph as both creeped up too high last week. I cant vouch for how well ph perfect nutes work when changed weekly as directed, but they cant go 2 weeks without being measured and adjusted, and at full strength, Im sure they would burn plants.
Day 2: ppms held steady at 1350 overnight, ph is at 5.8-5.9
New growth was showing very early signs of light burn, (pale leaf tips up top, tips not pointing down) so I turned light to 50% power, mounted it straight to my top tent supports, and bent the tops that showed signs of stress.
Day 3: Ppm's still holding steady as water level goes down, so this may be the sweet spot for now.
Bud sites are stacking now
Selectively defoliated to get light deeper into the canopy
