I actually..just foilar fed them last night.. With this stuff Called Revive from Advanced Nutrients. And a drop of Superthrive. The soil is still wet from when I watered 3 days ago. So I am waiting until it drys up alot more before I flush them.Maybe you should try some foliar feeding until you get the PH problem in your soil resolved. You can get something like Fish Emulsion and mix it with some water, put it in a spray bottle, and just wet the leaves down. This is the stuff I use, very mild, but will sustain your plants until you're ready to feed them again.
