Quadgrow - feed

After all recommendations here, I am into 2nd season of using Quadgrow for Tomato & cucumber crops ..... and when you see how much water they take up naturally in this weather, you realise how much you were getting it wrong.

For those that also use Quadgrow - do you continue to use the 2-part pack from Greenhouse sensations - or do you use some other concoction.

Just mixed my last 2 packs .... so time to ask the Q

I reads one post about feeding pots - but for me that goes against the concept of them taking what they needs form the water tanks.
So welcome advice if there is a more suitable (or better value mix)
