Newbie 300w LED closet grow

MariaJuanita710 Decided to grow after getting discouraged the last 2-3 times I grew. I was improving each time time but not as excellent as I wanted it to be. Since all the quarantine going on, I have been blessed to be home a lot more. I thought to myself I might as well try growing again since I still had all my old LED lights and seeds as well. Snoop Dogg OG is from a dispo bag, and the other is just some random bagseed I've been holding on to since it was a nice strain. I'm using the corner of my closet without a grow tent since I would rather use grow tent money for other things since stealth is not really an issue. Planning on using solo cups for maybe 2 weeks veg or so, then transplant to 2 or 3 gallon fabric pots. Using RO bottled water until I get pH/PPM meter later this week. I've got a small fan going to circulate the air. Just put everything in a box for right now, trying to decide best method to reflect light back for when they really get going. I like to do things on a budget so I've got a sunvisor taped to 2 separate pieces of cardboard that stand up pretty well. I will be using Fox Farm trio liquid nutes in about a week diluted from recommended schedule. Any tips, comments, or suggestions are greatly appreciated! I'm excited to grow since it really is a passion of mine to watch it grow from a tiny seed to an end product that helps me. Cheers!

MariaJuanita710 Surprise, surprise! I eneded last week with a feeding that I know I did not need. I gave a diluted dose of Big Bloom (maybe like 1 oz or 2 of nute/water mixture) to both plants on like the 5th day after sprouting. BIG MISTAKE! I was too excited and couldn't contain myself. I have been writing everything down in some grow journal so that it's easy to see what I did without having to remember. Both plants now looks like they haven't grown much since then. They did start looking yellow, at one point the Snoop Dogg OG looked like it was overwatered (drooping leaves). I flushed it today with plain water ( 6 PPM / 6.h pH), about 6 oz each plant. I did get some runoff and tested that as well. I tested runoff after much of it had drained from solo cup already. Soil runoff was ( Lando: 800 PPM / 8.2 pH) and for (Snoop: 438 ppm / 8.4 PH). I'm not too concerned with the runoff right now since I know that I fed way too early. I'm hoping that once I flush, they'll spring back in a few days. Humidity and Temp are 7 day averages as well. Now is a great time to start some self control and let these (hopefully) ladies tell me what they need, not the other way around!
