5th week and they look sick

From what I've been researching I think I gave them to much ferts.

First pick is week 4, second pic is week 5 (Today).

And I tried to read on flushing. Does that mean just to feed water only for a few weeks?

Are they gonna die?

on their 3rd week I gave them ferts. 1/2 the recommended amount on the box (Miricle Grow All Purpose) 1x that week.

4th week gave them the full recommended amount on the box. 1x

and now they look like this. Also all the leave tips are Dry

water them with ph6.5 water 1 gallon each and get them under some light dont water again till they dry out they will be ok

could it be too hot?

Do what butter 111 said you shouls be fine.. but dont let them dry out...and keep them under 24/7 light about 21/2 feet away from the top of the babys forehead. and you should be ok they look abit stunned but not dead so listen to better!

I thought it might be to hot. But no, it holds around 80f in there. Is it not nute burn?

and Dose Butter mean one gallon of water each plant in one day to "flush" it, or once I go through a gallon of water then add nutes again?

butter is right man. get that crap out of the soil.
