I didn't add CalMag when supplementing the tap with RO since I thought it would have sufficient levels in my tap water to supply them both. Now I have to head to the hydro shop and need to pick up something for the K def as well as CalMag (see PC, I'm finally bowing down to the Hound!).

What product did you use to clear up the K def? (I have symptoms of both MG and K issues) The store opens in 10 minutes so if you can let me know soon it will help me out...
MVP Reviewed by MVP on . Hydro Nute Problem with pics... Help Needed I've been trying to figure out what type of problem I have here. The bubbler hold 4 plants (2 master kush, 1 blueberry, 1 super skunk). Two of the four plants have the same issue (one MK and the super skunk), they other 2 seem okay, maybe slight P def. Leaf pics are from MK, they are the tallest. I also have 2 MKs in dirt in same room with no problems at all. Here are some details: -indoor -hydroponic -hydroton -DWC system type -Water is 1/2 RO and 1/2 tap -Water pH is 5.8 (+/- .1 to Rating: 5
