PLEASE HELP! 1 month 3 day old , plant problems!!!

I don't know what is wrong with my plant. You can go by the pics , please help!
Its' 1 month 3 days old , still in veg. Will gladly appreciate all the help I can get on what to do!

The majority of the plant looks fine. It could be a phosphorous defficiency. I would think about pruning away some of the fan leaves while it is in veg to let it breathe easier and to encourage some of the other branches with grow tips to stretch for the canopy. This will increase your yield.

check your PH and make sure it's 6.5-7.0. If you are using a non-soil medium, adjust appropriately. If you have never flushed, consider doing so and get ready for flowering.

i put some miracle-grow in it because i thought it looked hungry and was lacking nutes ...
When should i start flowering?
