Jack 47, 2nd run, UK Grow

This week did not go as expected. The plants are way smaller compared with my last run of this strain. I think the biggest struggle at the moment is maintaining the temperature. The light was a bit low as well, don't know if it had an influence on the slow grow DAY 10 - Water PH-5.75 Solution Temp-21 PPM- 632 Watering Volume - 2L DAY 15 - Nutes PH - 5.75 Solution Temp - 223 PPM-721 Watering Volume - 1.5L
