2nd Time Around

I started 1 gelat.og and 1 blueberry a week ahead of the other 2. All the seeds were soaked in ph'd water for 24 hours and then placed in a paper towel within a humidity dome on top of a germination heating pad. They all popped and had a small tap root with 2 days of placing in towel. So far they have been growing pretty well. I placed them into bigger rockwool cubes in hopes of being able to keep them in the propagation tray awhile longer seeing as I need to finish up my 1st run EVER!! I popped 2 bag seeds...1 turned out to be male and 1FEMALE!! Im so excited and can't wait to see what happens but thats not what we're here to discuss today. I plan on giving the 2 larger seedlings their first light feeding today (Monday 4-5). Let me know if you guys think im a little early or right on time with the 1st feeding. The seedlings are going into a 4 site RDWC system I made.
