Hey thanks for the tips,

I don't think the plant needs a fan because it's outside and theres a good breeze every once in a while. I noticed the black pot getting pretty hot so i put the black pot inside a metal pot (picture coming soon), it doesn't get quite as hot as the black one.

If the purpelish stems are in fact caused by sulfur deficiency, how do i go about correcting that? Is there sulfur fertilizer?

I've switched to watering the plant every other day now, it's very hot here right now, around 36 degrees celcius (95 fahrenheit?) every day and it hasnt rained in a while.

Cheers
Stefan
