My pH is wonky... I could use some help...

So, back for another post today. I had to take my t5 bay back to the shop, one of the six bulbs did not work, actually the ballast did not work. But, the new new one is up and shining bright.

I had some really bad yellowing and curling show up in almost all the plants, almost overnight. I thought I had burned them with nutrients. But, after a pH test found that my mix was at 5, maybe even a little closer to 4. I had not tested it yet into the grow. I added 1 tablespoon of baking soda to one gallon of h2o and flushed all the plants. I tested the pH again a few hours later, it was pushing up away from the 4 to 5 range, into the solid 5 range. I know it will take some time. I will be testing the pH a lot over the weekend, until I get a nice stable 6.5 to 7.

In would love some input on managing pH. I am working with an all organic garden, using a no soil mix consisting of sphagnum, peralite, guano, worm castings, azomite, micoreza. The mothers, which I am working on vegging to get clippings at this point, are in 3.5 gallon buckets. I also have some in 2 gal grow bags. I used the baking soda as kind of an emergency fix... What is the best solution for managing pH in the long term in a soilless mix? :leaf::leaf::leaf:

baking soda works fine.but realize its a HELLUVA lot easier to get ph down than up.it takes more chemicals to raise ph.sounds like your plants locked out get your ph good and you will be fine.dolomite lime works good too like bw said
