i can't say i'm familiar with dynagro, is it for soil? the reason i ask is because if you go with only perlite/verm. then you will be doing a hydro grow. you will need hydro nutes.

the pH will be completely different as well. soil runs between 6.3-6.8 with ~6.3 being ideal. hydro is between 5.3-5.8 (i think, i don't grow hydroponically yet). each strain has their own preference.

i use miracle grow soil currently and haven't had any problems that can be accounted to it. you just need to be careful when feeding as the soil has nutes in it already.

you shouldn't be using nutes on your plants until they have between 4-5 nodes. ESPECIALLY if you are using mg soil.

good growing.
