I am having trouble getting the soil ph down…it is staying around 7.5 to 8. I have been adding and adjusting the ph down to 3 now and still no progress and the soil will not change…the plant is showing a bunch of stress and the leaves are taking it hard. Any suggestions on how to get this in the right direction and save this plant ? It was started in early October and I want to get her healthy before I switch to flower. It had went from having 11 inch 13 fans to a miniaturized version now that is struggling but a pretty tough plant ! Plant is and has been for a long time 16.5 inches with four tops and six side branches with numerous growth tips forming up the branches. Would love to get it to branch out a bit more and get it to flower already as it is time ! Two clones have also been taken off with the hopes of them surviving yet to be seen
Strain; Would be a bag seed…indica/hybrid
Age from Sprout: October 7 was sprouted
Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: Potted in a 5 gallon air pot with a mixture of black sand/pro mix bx mycorrhizae/perlite. Was started off in a solo cup and transplanted into a 2.5 gallon pot…then to a 5.
How often do you water and how do you determine when to do so? Watered every week and let dry out till the top is dry down two inches. Problem is the plant is not using the moisture quick enough and the dirt is not the problem as it is porous enough and has a lot of perlite. Soil probe is used as well as a soil test kit.
PH of water and runoff or solution in reservoir: Using RO the entire time anywhere from 6.6 to 6.8. Started adjusting the level down with lemon juice and vinegar when the soil probe had shown alkalinity rising. First timer so thinking I can just keep adding ph down to fix the problem and no I have not flushed the pot. Started out being an unbelievable plant and is slowly withering. Was adding a 50 % felt mix of 15-5-5 and thought it would be enough to keep the ph in check.
