This week ended up pretty sunny. At 16 days from seed, she was already half a centimenter wider than the Green Crack plant was that I had from the Rainbow Mix, and that thing is a bushy monster now (update for Day 21: now over 5cm wider than the GC was). It's nice to see this because I'm trying to only compare myself to myself for now.
Tragedy struck on Day 16. I'm blessed with ignorance about what thrip damage looks like because I've only ever had fungus gnats in my houseplants, so I didn't recognize that some of the older plants had thrip damage on the leaves. I honestly thought from the rain or something because it rained in on them a bit the week before. Luckily, it was pretty minor, and I managed to manually remove what ones I could see. But I still went to my local growshop the next day where they hooked me up with something to spray on the leaves and soil (https://www.greenlight-shop.de/Neudorff-Spruzit-Schaedlingsfrei-250-ml). I sprayed everyone down after sundown and left them out overnight. Nobody died!
