Hi there if you’re going to be at home then you can monitor your crop and how they are holding up. I can see you’re using the GO line of nutrients I’ve used them and think highly of them especially the kelp product Bio Weed using this in combination with your Dimond Back you’re plant will be able to handle the heat much more effectively. Start feeding it light feeds whilst it’s cooler. Then do a heavy feed with good run off to saturate the pot on the morning of a day you expect to be hot. Be careful not to overwater though as this in turn will have negative effects when it’s hot. If you would like a tip get a airstone and pump and always bubble your water 24 hours before adding your nutrients. Good job so far!
