Hey guys, I need your help my purple cheese autoflower is 2 weeks and her leaves are yellowing. She is growing in Happy Frog soil, in a 4 gallon pot, under a 150 watt sun system hps. She's in a Secret Jardin DR60 tent. I watered her yesterday and her Ph was 5.8 went back to check the PH is was 6.5. the water I watered the plant with Ph was 6.7. I haven't introduced nutes, also the plant is a little top heavy. The leaves are weighing the plant making it lean over. although it it yellowing it is still growing. I currently dont know my temps but I keep my tent open.
