When can I start Fertilizing

My seedlings are about 1 week old I was wondering when is the best time to start fertilizing or misting the leaves with fertilizer I was gonna start in about a weeks time help !!

Once the plants have lost their cotyledons and true leaves emerge it is time to fertilize. Go lightly on the fertilizer for the first few feedings.

The plants initially feed off the cotyledons or false leaves; to establish first leaf and some root. At the second set of leaves is generally when they start eating through the roots and need a boost.

Always make fertiliser 1/4 strength at first; you can always add more but it is hard to undo a nute burn.nigel

Synchronicity Buzzmobile; lol, nigel

this is the seedling now should I start wih 1/4 strength fertilizer? I am using a liquid fertilizer with Notrogen 5% phospherus 3% and Potassium 8% is this good? with some trace elements like iron is this ok?

good day, myself i would wait till i had a couple sets of leaves if the soil is not fortified you WILL need to feed sooner but a plant that small you will be on a touch and go as far as nute burn. when i grew from seed in reg soil i would wait until they were 6 inches before i fed them it gives the plant time to make good roots and allows the plant to get larger. it doesnt take much to fry a seedling. good luck,

So ill wait a couple of weeks and start then also is the fertilizer I am using good? 5.3.8

i would think that will work, what kind are you using i use ionic grow 3 1 5. with the flood of this stuff out there i have stayed with what i have used for a long time and before michigan was medical i could drive to lansing and buy it off the shelf. its bad when the only grow shop was 60 miles away, now i have one less than a mile from my house

This is kind of a question to anyone watching? Last time i fed in my FFOFS...i gave half strength nutes and still got nute burn. This time around when i feed will my plants be able to handle half strength or should i go 1/4 strength? I am pretty sure the reason she got burnt was i gave her half strength nutes right after a full sledgehammer flush...15 gallons of water through each 5 gallons of soil. Any advice would be appreciate..and to the OP looks like you got some good advice congrats on the sprout!
