70x70 BCN critical, 200w lumii black

I found out by measuring the water going from the pot that I probably over fertilize the plant. My mistake Was to use some cheap guano from local shop to the pot directly and also full plan with shogun fertilizers. I find out it before leaves start necrosis and now the plant is on diet with 1,4 ec and i control the outcoming water every day to be sure that situation In pot is better. Colas still growing but it slows a bit and will do some impact on my yealds at the end for sure. I will learn from my mistakes ! You can seen on pictures some improves on vent system, keep growing guys! Keep improving 👌🏻🤩
