Need help with general hydro growing schedule

Hey guys. this is my 3rd grow, im running a 400w MH/HPS combo. I'm gonna have about 5 plants growing (bought my seeds from gypsy nirvana-White widdow, White rhino, cheesus, iced grapefruit and some haze hybrid.) All these seeds flower for about 9-11 weeks. I'm using general hydro 3 part for my nutrients(grow, micro and bloom.) Now there is a couple of areas i would love help with.

1.Does any one have a feeding schedule that has worked well for GH. in the past i feel i've often over nuted my plants a little. i need to go a little lighter this time for sure.

2. I also have big bloom liquid. How should i work this into the feeding schedule. I would guess sometime during flowering i add this in. but how much and when?

3. ive read that the order which you mix the nutes in matters. (micro,grow,flower) is this true and if so what order would bloom be?

Thanks fellow dadis-es.

1. Just follow the instructions on the bottle. Unless you're using their expert line, the feeding schedule on the bottle is pretty good and wont give your plants a hard time.

2. Who is big bloom made by? What is the NPK value? It doesn't really matter I guess, I wouldn't add it regardless.

3. Add to your res in the order of M, G, B. Mix in between each addition. You don't have to be anal about it but they just don't want people premixing nutes in their concentrated form.

Lucas formula is very simple and generally safe for plants, 8ml Micro 16ml Bloom per gallon. If you wanted lighter just keep it at a ratio of 1:2 ex. 5ml Micro/10ml Bloom

Good page on nute profiles.

sorry i meant to say liquid koolbloom by GH. not big bloom.

The bottle schedule has seemed vague in the past. there are more slots(weeks) for veg-ing then flowering.

I'll PM you my feeding schedule.
