ChemCookies - First Grow

Pictures are from the start of week 5 bloom cycle. The pine smell is getting stronger with each day. I lolly popped them a bit more. Pulled the CO2 down to 1000ppm. Adjusted water temp down 1°F to 66-67°. The total Nutrient volume is only 18 gal (68L) now as the root balls are taking up approx 6 gal. (22L) of volume. Airflow to the root system is 26L/min via two 8" circular airstones. The Apples & Bananas is 8" taller than the GMO Cookies. Ooooops. This has caused me to angle my light 45° to allow for an av erage LUX of 48,000 to 74,000. Obviously these two grown together is not an ideal combo. This is my first grow, so my ignorance as to how big that strain will get coupled with the lack of proper management has led to interesting results. Night temps outside are in the low 50's so utilizing that cool & dry fresh air has been great and hopefully gets those girls thinking winter is almost here. As usual, I let the solution swing around without micromanaging the pH unless it's outside the range of 5.5-6.5. This week it was almost steady at 6.1pH. No adjustment was needed. I noticed the TDS (700) was slowly climbing. I assume this is a nute imbalance. It was water swap time anyway. Nute add-back is once every two days, consisting of 4 gallons. Streptomyces K61 seems to bring the pH up by 0.2 to 0.3 once added to the solution and mixed in for 2 hours. Humidity is higher than I would like. I should get a dehumidifier. The airflow into the root system pumps a lot of humid air into the tent through the lid and cup.
