When to start feeding Nutes?

When is a good time to start feeding my clones Nutes???

They are just over 3 weeks from when they were cut. They are Heavily rooted and growing great!

Pictures....

I would go ahead but ease them into dont just bam em'

Like 1/4 strength or so?

yeah of if like you know you use a set amount of water/nute each time reduce the nute by half ...like I do 1/2 gallon of filtered water to 1/2 teaspoon of grow big if I were beginning I would do 1/2 gallon of water to 1/4 for the first couple of times then move to full value then watch them change before your eyes!!!

go with 1/4 strength for now once every third watering for 2 times; then go with 1/2 strength for same then 3/4, then...until you are at full strength

yeah quarter strength. i would recommend feeding every other time you water. See how your plants are reacting and then step it up to 1/2 and so on as long as they aren't getting burned.

Just picked up some fox farm Grow big
