Day 50 first day of flower plant will definitely double in size on the great white shark 🦈 it so beautiful. Northern light in the back room corner may have a disease not doing well growth has be slow on pistils and leaf growth. Shower plant is just coming along. Day 51 great white shark is showing signs of flower and the room I'm having trouble at night with humidity I have dehumidifier but don't seem to work correctly. Day 52 Refilled resivors all at 540ppm 6.3 great white shark and the Blueberry are growing very fast since the flip. Northern is still slow and looking sick I'm sure it has a disease. Day 53 plants growing great finally got humidity at night to be around 45% plants are really drinking alot. Day 54 refilled resivors 500ppm to 600ppm ph'd 6.4 Day 55 refilled resivor on great white shark this plant drinking alot much more then the auto's. So be aware photos are drinkers. Day 56 plants are doing well was told to flush the northern lights so we will try sounds like this plant has pest or nutrient issues or maybe this plant doesn't want lots of nutrients we will see.
