hey kent...

it will be ok.. You will get some burnig on your leaves.. but you will recover... Don't get to upset at your friend.. it is never worth getting upset ... the grow is suppose to bring you happyness.. make sure it does..

Please post pictures....

I water with a solution that has a pH of at least 8.0... When I have grown in MG soil, which has a pH of 5.0 -5.5 I always water with 8.0 (for teh first 4 weeks) and the plants turn out OK..

Your biggest problem will not bethe LOW pH but rather the massive fluxuation.. plants don't like the sudden shift...

please keep us posted and LOVE thy FRIEND...
