Here is Day 37 of Flower. Today's date: April 20, 2021
Grow: 4 Gorilla Glue and 4 Blue Haze in a 5X5X7
Last Top Dressing was 2 weeks ago
Still adding a small amount of molasses, Cal Mag and a 0-10-10 at 1/8 to 1/4 strength depending on the strain at a pH of 6.5-7.5
I keep having pH problems. Every feeding I check the pH of the water to ensure what goes in the dirt is pH at 6.5-7.5; however, 4-5 days later, the soil pH keeps dropping to 4.5-5.8. This has now happened 2 weeks in a row. I assume the microbes in the soil breaking down the organics is causing this. I start my slow flush (10-14 days) this weekend to prepare for harvest. I'll be surprised if it continues to keep dropping during that; however, since I'm aware of it, keeping it under control by applying a small amount of RO water (1/4-1/2 gallon) set with its pH a little high (7.6-8.1). I'm finding the small amount of water with a slightly high pH works better than a small flush (1-1.5 gallons of water) that is set to the pH I actually want.
