No, your pH is way too low and you are locked out. Flush with pH 7 to bring it up to the 6.5-6.8 range and give a final flush with a complete fert. I see primarily the symptoms of Ca lockout but that isn't the only thing you have going on there.
stinkyattic Reviewed by stinkyattic on . Magnesium Difficency? What ya think? It's not really effecting alot of the plants, but the leaves that are effected are in the middle of the plant, not at the top which has me a bit confused. I have recently added a bunch of fans so I thought the few that were effected was possibly wind burn, but a few more have shown up with a few odd signs... Had a friend say it looked like mold, I personally don't think that's the case at all. Using SuperNatural Bloom pH 5.7-6.0 Medium SunShine#4 Rating: 5
