Plant keep growing great.
As you can see at the leaves there are some of the tips of the leaves with bad color, thats because teh EC reached up to 1,8 so I added ph leveled plain water with 0,4 ec to lower the ec to 1,5 and the plant is responding really well, growing faster and with a healthy root system.
The temperature was high also (near 30 degrees celsius) so i moved the lamp upper and i will setup an 100mm fan for extraction. The led panel is really really hot
