Help please I think I burnt my girls!!!

These plants are growing in half ffof and light warrior with perlite. I just checked soil ph about 3 inches deep it is 6.0-6.5. Yesterday I fed them for the first time with 3ml of pureblend pro grow to one gallon of water,the plants are 2 1/2 weeks old and on there 6th set of leaves. They were fine early this morning than I just checked on them and two are showing this yellow rust colored speckling on the leaves and burnt tips on first true leaves. I don't get it they took off last night and looked great this morning. Please someone help I don't want to lose them.

FFOF is already hot, and you are feeding too soon, so yes, you will burn them. give them an extra drink, let them dry out, and wait to feed. 5th node to be safe.

I contacted hydronerds and the guy says add iron I think hes way off as it just occured since I fertilized it. Could this be calcium deficency from using distilled water?

So should I give them a flush right now even though I just watered yesterday or let them dry out and flush in 3 days when I water again?

Water like you normally would, just no nutes and it'll recover.

edit: so no, you don't need to go all crazy and flush.

Thanks a lot guys I just hope it doesnt kill them before the next watering ,they were looking so great....

The PH of the distilled water is 7.0,I don't have a r/o setup in my house. I just watered yesterday so I should wait till my next watering to water right?

Could some of this be caused by too much heat from my cfls being too close? I have a light over each plant with two 20 watt cfls on them and I put my hand down there and they were pretty warm,the lights were only 4 inches away so I lifted them up to 7 inches away now.
