Update - Day 29

hmm, I went out before to water my plants and realised that my backyard soil sunflowers are getting a lot greener than the other two. I wonder whether the drainage hole has something to do with this.. because I'm pretty sure the hole for my backyard soil one is bigger than the others.

And yesterday it DID say "more nitrogen needed" for the plants with a lighter shade of green. but, do you get nitrogen through the hole?

I'm not really that good at science sooooo, yeah. I shall research that further.

hahahah (:
