Auto harvest 5 plants from seed

Ok so this week i found out I was only gaveing the plants 0.4 nutrients each and not the 4mil as was planned so when I found out I gave them all 2mil and will be upping it to 4mil tomorrow I was using an old baby syringe that was from 0.1 to 0.9 I never noticed i Have the right one now. Few things I found out this week was my big plants was getting wind burn so I moved the plants around and one of the smaller ones mite have been just starting to get root rot or heat burn not sure so I moved it closer to the fan to dry out the soil a bit faster seems to be working all in all there doing good and growing fast some nice Frosting starting to form from the buds and trichomes starting to show hopefully they take to the 4mil nutrients good
