Elo! nice work so far, they're always so cute at this age
I've got some questions, just want to know so I can help you out, I'll follow this grow till the end.
What type of soil are you using?
Do you plan to get more lights as the grow progresses?
What are you going to transplant into?
I would suggest finding an alternative to the MG all purpose nutes. If you only have access to MG nutes, you should use the tomato food (18-18-21) as it's much more balanced.
If you can, just get a hold of some quality nutes over the web, I promise you it will be worth it.
