If my plants were six weeks into flower here is where I would be #wise

RO Water.........15ppm
CalMag....300ppm
Pro Bloom 350
Hydroplex.350 (these are both blooming nutes and together equal 700ppm)
Liquid K 7ml/gallon
Sweet 7ml/gallon

and my numbers would be about 1350 total. Your entire ppms are too low iimo.....especially for six weeks in.
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
