ive got the GH 3 part and cal mag . i used gh 3 part for 20 yrs. when i had these probs with that, iwent to the powder to simplify to see if the results were different and i was mixing a bad recipe. theyre the same so ill go back to gh3 pt as you suggest. yes i had the rockwool cubes in the net pots. i got the system and had the clones cubed so i just poppped them in to veg to get clones with some rocks on top. is this retaining too much moisture?? ill get the karma and B1. BTW is my nute recipe i listed earlier seem in the ballpark???
