Gorilla Glue and Blueberry autos in Fox Farms Ocean Forest in 3 gal pots, week 7 from germination. 24/0, temps 73 +/-2, humidity 48-58%
Watered with tap water, pH 7.5 up till just recently. No nutrients or amendments beyond a small amount (<2 cups for 3 gallons of soil) of Black Kow added to the soil when filling the pots and about a tbsp of DynoMyco added and watered in around week 2.
Noticed leaves beginning to fold upward along the central rib, and the ribbing becoming more pronounced over all. Newest growth has tips beginning to twist. I initially thought I had my lights too close (2 600TS's at 18", so I backed them off.) Today I notice the Blueberry is showing spots on the leaves. Lower leaves on both plants fared badly early on and I wrote that off as burn from the hot FFOF as they seemed happy otherwise at the time.
Issues persisted so I used a 3 in 1 tester to measure soil pH, which I didn't intially believe as it was reading 7.xx, when I've heard FFOF runs acidic. To my horror, over the next couple days the pH continued to rise, closing in on 8 per the 3 in 1.
Edit- so seems like the tap water may be the culprit due to calcium.
Any sage wisdom to offer a humble newb on his 2nd grow? Does this look like it could all (leaf formations and spotting) be chocked up to the pH going too high and starting to lock out? What's the best way get the soil pH down? Watering with water distilled or filtered down to <5ppm and pH'd to 5.5ish for a few rounds? Thanks in advance for any advice.
