Feeding schedule help !?

Hello.
Ive been looking for a while and havent found no concrete answer.
I have a buddy thats growing in soil and we were argumenting on what the feeding schedule would be.
Lets say for flowering kush indoor in 10L pots soiless mix.
Using advanced nutrients sensi grow, sensi bloom, candy bud, big bud , bud ignitor.
My question is, on the schedule lets say they say feed 1300 ppm on 3rd week.
If i have to feed more then once that week should i give it the same solution or half dose the second time or plain water?
I confused in all this !

I am a soil grower so don't really know, but seems to me. I would think that a steady diet of the nutes would be better for the plant and its' grow cycle. The added advantage is that it is easier to increase or decrease your use by watching the plant and reading it needs. Look at the color of the leaves and they will tell you where they are at in their needs. Once you find the proper color in your strain it is only a matter of maintaining that coloring, remembering that it will take several days for the nutes to catch up to the appearance in the plant. You have to be flexible when growing, you might try a side by side one at full and one adjusted with each watering to see what works best for you.
Happy Growing
