Nice plants and fruits and good advice from many people on this thread
I grow a lot of chillies and often see people recommending Chilli Focus. I know there are plenty of positive reviews, although these reviews are usually only anecdotal. It's rare to see somebody say they fed half their plants chilli focus, half their plants tomato feed, then monitored the results. And if they did, most people don't grow enough plants to make any meaningful comparison when taking into account all the other factors.
Personally, I'd be interested to know more of the science behind the Chilli Focus formulation to justify the claims, as it's certainly not obvious from the formulations. I've done a comparison of the NPK+ formulations of Chilli Focus and several widely available tomato feeds, and Chilli Focus is typically 4 times the cost, and roughly half the concentration in terms of NPK+, so in effect it's roughly 8 times the cost. Obviously if you feel it is a better product, then it might be money well spent, but I'm not convinced.
Chilli growers often think their plants need more Magnesium, but Chili Focus doesn't even list the amount of Magnesium in it's formulation.
Of the commonly available tomato feeds, my personal suggestion is Westland Gro-Sure: NPK+ of 6-3-10 plus Magnesium and Seaweed. Magnesium at 0.02% is higher than other tomato feeds I've seen.
