This is my second grow; the first was sketchy but i did manage to make it through to harvest. I learned a lot.
This grow has been a lot smoother but for several weeks now I feel like my soil PH level is on the low side. Yesterday I noticed what I think are signs of a Potassium deficiency so the PH level is back to the forefront of things.
I am in 3 gallon fabric containers with Fox Farms Happy Frog. I water/feed about every 3-4 days using scales to keep tract of their weight and thus moisture content. I feed with 2-3 liters to 20-25% runoff.
This log shows the PH of my feed and the runoff since I transplanted to their final containers. It always comes out lower than the input levels and seems to like staying around 6 or a bit under regardless of the input PH level.
I did try to bump the PH level up using a bit of hyrdrated lime mixed in water to a PH of about 9. After this treatment I didn’t notice any real change in things.
I did a slurry test… after 15 minutes I got a PH of 5.6. Retested after 24 hrs and got 5.9.
Anyone have any thoughts or recommendations?
