This was probably the last 'normal' week with ideal conditions.
Now it's soaring up to 38C and roasting hot - this is where it gets tough.
On reflection, this is still better than previous grows. If I had started earlier (I usually start late April outdoors - this year was late May start) then I would have caught a LOT of bad weather - lots of cold and lots of rainfall.
Just need to keep them cooler somehow.
Added two new nutrients to the kitchen sink - Jungle Juice and Top Max - just stuff lying around from last year. Given that I have bombarded them daily with all sorts of nutrients, I am not seeing anything remotely like nutrient burn, etc. They all look great.
