Am I screwin myself here

I have been puttin a little miracle grow 8-7-6 in my rez but my plants arent growin very fast. They shot up a couple inches at first out of the RW cubes. Im thinkin this miracle grow is for dirt growin and thats part of my problem besides possibly ph. Does that sound right? Im usin dirt shit? I should have grabbed that Floranova at the hydro shop yesterday. Ive been tryin to piece this grow together.

yep, you can't use mg in hydro; it falls out too quickly.

you need a formula that's made for hydro.

dam ok thanks

When you get it - make sure you get both veg and bloom so you're ready for both stages.
