Back into Growing

Hey guys it has been awhile , but I gave up growing peppers with all the problems(mainly Deer eating every thing).
 Now think I have a solution to the deer so want to get back into growing.
Long story short. I had a couple Datil and Ghost that were still hanging around but I think just surviving. I had a problem before with PH an not sure what to do.
The plants ave really small leaves, light green , no flowers, , but still alive.
I just checked the ph with one of the checkers from lowes, and it is around 7 on just about everything.
Any suggestions as what to add to bring up or lower lower ph????
Thanks

Off the top of my head..

1. You can use 'PH Down' (phosphoric acid) to bring down the PH of you feed water.

2. Adding well composted organic material can help correct PH.

3. Garden Sulphur can be mixed in with your soil and will lower PH.

Good luck

*Btw.. 7 is not too bad you only need to get it down to 5.5-6.5
