Soil PH issues, need some advice.

Hello RIU!

I've been vegging a Dutch Kush fem for about two months now, about to flip the switch and I started noticing what looks to be Calcium, Magnesium, and Iron def, due to really low soil PH.

Started her in Espoma Seed starting mix in a one quart until transplant into a 5 gallon bucket of straight FF Happy Frog soil. Nutes are FF soil trio and Epsom salts. I didn't feed until week 6, after transplant and even then I used it at quarter strength according to the feeding schedule.

I determined my PH was low by testing runoff from my last watering. I put in plain gassed off tap water at 6.5PH that came out the bottom at around 4.8!! Yikes! I immediately flushed with about 10 gallons of the same water from above (with a heavy dose of Big Bloom in the last gallon). I don't really have cash in the budget right now to run down to the hydro store to grab cal-mag/ph up or down, or even to go grab some calcium chloride.

Any tips on how I can quickly address low soil PH, without hurting my girl. I've been using Distilled Vinegar and Baking soda to PH my nutrient solutions. Never need the vinegar for the FF line. Just a little bummed this may add a few weeks to the veg cycle. I don't want to flip the switch on an unhealthy girl. Any and all opinions are welcomed. Thanks all!
