started the week with a problem. I was watering with 1 gallon 6.5ph water but getting 5.2ph run-off. This seemed problematic to me as i had understood that a PH of 6.5 at the root zone was essential for the plant to uptake nutrients. i fed the plant with 1 gallon 8ph water in an attempt to lower the PH. (this gallon was not accounted for in the watering log) I was later told not to worry about the run-off as the soil would take care of the ph. So, some of the leaves seem to be showing signs of fluctuating ph, understandably. The growth this week haqs been nearly none, however, in the past couple of days i do seem to see a very slight fattening of the bud sites, but its very small. My plan is to water with 6.5 water till the end and to ignore the run-off ph, I guess i should mention that this is a "Just Add Water" bucket i bought off the internet. I have no idea of what nutrtients are in the bucket organic or synthetic ( but i did see those little time released green dot fertilizer balls
