Nutrients

I am growing indoors and currently my plant, since I am only growing 1, has been growing 16 days since sprouting and is about 6 inches tall give or take. I am growing it in some miracle gro soil with 6 months worth of food in the dirt already so just curious as to if I need to add nutrients at all because I would prefer to grow without if possible. Any advice as to when I should start feeding them nutrients if I have to would be awesome. I am currently running two 40w daylight cfl's for vegging and once I receive my additional clamp lights I will be adding two 40w soft white cfl's as well. I also have one small fan blowing very indirectly near the plant so that it gets just enough breeze to barely move the leaves around as well. Thanks ahead of time for any advice!! I am new to the growing game and just trying to learn as much as I can ahead of time so I am ready. The seed I am growing is of unknown strain since my dad and I found it in some really dank stuff we had a couple months ago.

I'm pretty new also but I will try to help. I was told by an experienced grower that nutes arent needed with MG soil. He said it wouldnt hurt to just add some weak nutes but you will be fine without it. I'm also growing in MG. mine is organic choice though. Good luck!

That is what I figured using the MG soil, but wanted to ask just to make sure. Plant is plenty healthy enough as long as I can keep from overwatering it. Going to take a picture of it tonight and put it on here so can see if it is where it should be for its age.

generally people do not want to use MG soil with cannabis as its ratios are slightly off and you lose all control over feeding. You also cannot flush the plant because watering it more causes more nutrients to be released into the soil further compoundign the problem. Use regular soil mixed with compost or a million other soil recipes. Good soil like roots of fox farm OF is not that expensive and the results are much better. If you want to go cheap,go cheap with the nutes or just buy tomato food ,don’t cheap out on the soil.

This is what the plant looks like after sprouting on the 3rd of October. Will do much better once I add my two other cfl's in a few days. Seems to dry up fairly fast though and not sure if I should keep watering it because I can stick my finger in a few inches and its dry so I water it good and 24 hours later it feels damn near just as dry. Is this normal or is it just drinking alot and should I keep watering it until it slows down some?

Water by weight of pot.
