Nutrient dilemma

Ok im trying to put together a good feeding schedule for two female plants that I grew from seed there in Happy Frog soil about five gallon pots each they both stand about 5 feet tall. I have been using foxfarms Tiger Bloom and Big Bloom together in the same serving ive added just a drop of superthrive every few waterings with the TB and BB giving it 2 teaspoons of TB and 3 table spoons of BB everyother watering.
The plants just started flowering and completely healthy and strong they seem like heavy feeders because of the nutes ive givin them and it seems like it worked but not much also flowering is slow but maybe not. Im wondering if maybe they
getting slow start to flower or im not
feeding enough. Should I give nutes every watering or still with every other watering? Is anyone else having slow outdoor flowering as well? Maybe im just worrying too much they are sativas im pretty sure so I know they can go awhile.Just looking for some advice as far as feeding goes. I also use diamond nector everytime I give
nutes also so I know the plants are
using the nutes and there are no
signs of defiencies. In the past I
would give nutes every watering I
never usually have plant problems
im pretty good at solving issues im
just looking for some advice for a
simple nute schedule for what im
using I know FoxFarms has a schedule but im not sure I really need it. I also have some Cha Ching which I was gonna use last couple of weeks before final flush. I was also curious if I can mix cha ching with other nutes towards last few weeks of flowering and if not when should I cut out the TB and BB and begin giving Cha Ching? Id really appreciate any advice thanks..
