Black cherry pie x18 in a 1.2 x 2.4

Week three and the plants are doing better, still some signs of nutrient burn but the new growth is coming though lovely. Temperature has dropped this week outside and even with an extra heater I can only achieve 23c. I’ve re topped a few plants to try and maintain an even height and let the smaller ones catch up a bit. Apart from that all I have done is take some burnt leafs off and watered with de chlorinated water at 6.5 ph, the “all mix” pragron soil is very hot compared to the light mix. I’ll probably stick to using light mix once all the all mix has gone
