Hi mate thanks for your time. I have been adding notes for 2 weeks as they were super weak to start with and growing in light mix mixed with coco. I had to do it this way as our soil order was mega delayed. They were doing fine some of them are quite small and grow mega slow where others have a good progress. I'm using ts1000 and blasted2 x 250w ( our of 600w ) orange and blue. 18inch and 2o inch away.low WATTAGE as could not handle the temperature issues. Ordered mars hydro 1200 DAY Humidity 35 Temp 30-32 Night TEMP 26 H: 56 Feed with canna products. So NPK Individually plus canna vege, silica, rhizotonic. Water ph 6.5. Might it he the soil ? Thanks a million ! X
