Naw man, just take it by the schedule. I've never had a problem. btw I wasn't trying to be brash but people on here don't bother answering questions unless their phrased right.
I started with the GH general (3 part) now I use the one part Flora Nova series. I like it. Buds taste more organic. But follow the guidelines and if your feelig frisky up it a little bit at a time until the plants show sign of overfertilization but take it slow. and if its your first grow I would stick to the instructions untill you get a feel for them. Good luck bro...
