I'll take a couple of guesses but thats really all they are....guesses.

1. Maybe need some CalMag.
2. fert building up in the medium. I've had this issue both in hydrotn AND higromite rocks but I use a drip system so...as I said.....guess. But the nute buildup in my medium REALLY played havoc with my plants.


MVP....what kind of ppm meter do you use?
Weedhound Reviewed by Weedhound 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
