I'm pretty sure Micro is made by GH.....PC can you post a link to the product and I can check and see.... I do know Latewood's formula is for 3 part GH nutes, not the Botanicare which is pretty much an all in one product (except for your Calcium, Magnesium, etc which is all in your Cal Mag.....and all your cool trace minerals too) That's why I'm strongly suspecting that with RO water if MVP uses CalMAg his problems will disappear (hint hint )

The two minds I try to follow the most are my hydro guy and Rhizome. Interestingly, they have opposite views on the use of CalMAg during bloom. My hydro guy likes CM for the entire grow (which is the way I do it and always have) and Rhizome.....reading from the MAKERS of the product (Botanicare) says that CalMAg should be dropped completely from your plants menu during late flowering (I have never done this.)
As a compromise I ended up using a higher amount of CalMAg than Botanicare says and not as much as my hydro guy recommends BUT I still use it ALL THE WAY through my grow until flush time.

MVP I'm not familiar with the DutchMaster root conditioner. Do you have a link I can look at?
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
