Hey guys, Im so glad I found this place. I have been getting mixed information online and really just need someone with experience to tell me a solid yes or no regarding transplanting my seedlings. I planted them in a seed tray for vegetables because it’s what I thought would have made the most sense at the time. Now I know a red solo cup would have worked just as well - better even. seedlings were planted about 12-24 hours apart due to the tap roots popping and growing to length at different times. They planted on April 12th, 13th, and 14th. I’ve noticed that the seedlings planted on the 13th and 14th have essentially caught up to plant 1 and have all stopped showing signs of growing. Their stems are also turning red which one article said was a sign they’ve outgrown their “pot.” Are my babies OK? Or do I need to transplant them to a solo cup? Some say 6 days in a veg tray, others say wait for 3-4 true leaves (no signs of new true leaves for a few days now). I’m using a soilless mix which I’ll add photos of below. This is my first time trying to grow anything. I don’t expect a perfect 5 oz plant but I’d like for them all to at least make it to harvest. I haven’t been testing pH or attempting to keep humidity at a certain level as I don’t have the set up yet (maybe next year). Is it too late to start adjusting pH? Should I transplant these babies to a solo cup for more nutrients? There’s so much out there and so many opinions I don’t know which to follow. Any help is welcomed. Thank you!
