What is my problem?

[bigjb]

Can y'all take a look at this and help me out? I've got two strains (Super Silver Haze and African Queen X Jack Herrer). in an 8 pot waterfarm system. This is my second go 'round wit these strains and I've done 5 previous harvests in this system with other strains over the last two years. My temps have been a little cold. (65-75) and my PH of the solution is running from 6.2 - 6.5. I thought it was a Nitrogen deficiency, and I upped my nutrient strength and foliar fed a 70% diluted solution as well and now a week later, I don't see any change. I did go from hydroton to coco coir medium this time around, but I used the same coco coir in one pot last time, and the plant loved it. I'm thinking I need to get my PH down some more, but I ran out of PH down, and I live in a non mmj state, so running to the hydro store isn't an option. Any suggestions?

Baking soda for up, lemon juice or vinegar for down. I have used the baking soda method but not lemon juice or vinegar.

Food products do not work well to raise or reduce pH. mI woul;d recommend doing as Mono recommended and get some pH down from some place online like Amazon.

aspirin will work a day or 2 til you can get some regular ph down.

Thanks, I ordered some ph down a couple of days ago, but I didn't pay for the expedited shipping, so I won't have it for a couple more days. I'll try the others in the short term.
