Pictures attatched below. The plant is in soil and i feed once and water twice. I'm using RAW nutrient line.
What are your temps, high and low? Usually that purpling is caused by cooler temps which affect the uptake of phosphorus.

Night time temps are about 18-19c and day time temps about 23-24c. But i now think i may be having PH issues. I think I accidentally pressed the calibrate button on the ph and messed things up. I just recalibrated now. What is the best way to check the ph of the soil and amend
