First time grow - Pineapple Express x 2

So this is the week I found out all about PPFD, PAR and LUX, basically all the basic info one needs to understand how lighting works. So I brought down the 300W LED I have down to 18cm from the plants since that's the spot where I get 1000 PPFD. Since I don't have a quantum meter to measure this directly, I instead measured the LUX output of the LED light with a free app on my phone and then converted the LUX to PPFD using an online converter. Also bought real nutes, more specifically the GHE Flora Duo 500ml tri-pack. As a result I also switched up the feeding schedule, so now I'm feeding them every three days, and doing water only every three feeds. A bit late in the process, but hey, first grow! 😅 Finally, the first amber thricomes are showing, yay! 😍
