Is getting chilli focus an absolute must? I only have the one chilli plant (plus 8 or so tomatoe and 8 or so runner bean plants) to look after?
Not really but I found that tomato food is too rich and baby bio seems to kill more things in my hands. Chilli Focus does work really well though. However if it's a new plant and repotted it's likely to have enough in the soil anyway. Chilli plants evolved in areas without much nutrients and varied water.
What do you mean by "30cm may be a little too hot all day...." ??
Younger plants may not survive in blazing hot conditions because they don't have enough roots to absorb enough water. So keep an eye out on it.
If it does dry out - dunk in water and leave for 20 mins, take out and drain - then leave it for a couple of hours away from the sun. Mine have looked dead but revived before so try to revive it before condemning it!
