Day 46, plants are slowing down. They'll be one more push, but this will not be like the last week and a half so itsbtime to slow things down. I see some signs that i need to reduce the nutrients. Signs being slight tip burn on a very few the fans with a hook upwards indicating transpiration doesn't balance with light intensity, more noticeable and trustworthy signs are the darker shiney/waxy leaves inside the canopy. I'm not sure if my video uploaded or its quality while I write this, so I will comment on that later. Being only 3 weeks until harvest I've also cut the CO2. If looking close, the upper buds are starting to throw new pistils and elongate indicating that the co2 and heat may cause foxtailing if I push any further. I've reduced co2 from 850 to 650 and light from 1000ppfd, to 850ppfd and then this morning to 700ppfd. End of next week I will reduce even further to around 550ppfd before the last week at 400ppfd during the flush. All this lowers the temperature and slows transpiration. I've reduced the EC from 2 to 1.7EC and turned on my mister as well to maintain humidity to 55% . One less variable to worry about..humidity was fluctuating 47-53% last week. Higher humidity also slowing transpiration of water and nutrients. Hoping these changes have set the girls up to only get just the right amount to finish pretty.. Next week, tomorrow the nutrient mix will have full tilt instead of the bulkyB.
