Got abit hot this week but plants grew ok . The main plant has fully rooted out the 5 gallon pot and is taking up bout 3 litres aday. Might try 2 litres every 12 hours with it and the smaller plants are swelling alot. The main plant has 26 main branches all in light and some look like a small plants their self.
1.8 EC is kind of the max I usually go when feeding in flower stage, some others like to feed less, around 1.5 EC; If your plant is happy and not showing signs of overfeeding, then go ahead
