Oh, I get it!! I will study more about nutrition… still is a hazed area to me…
But you guys did makes me pay attention on the lights… I’m testing a led panel made by a friend and its have an UV chip led with 10w… I thinking its too much if we put it in comparison with the Quantum Boards, the UV leds proportion is minor than mine.
The other plant is under a similar panel but instead an UV chip it have an “fullspectrum” chip led… and that plant dont looks diceased.
I will pay attention on the next days… I will install an on/off button to that UV led an led it off for some days until this plant gets more mature…
This week will arrive 3 quantum boards from china and the grow will be more safe… in terms of know what we using on … but this leds did makes my start possible… so, thats it… thanks everyone for take a time to help this poor pothead…
