when do most of you start your plants on the basic a and b?

I know everyone is different and last time round i didnt use any nutes untill they had been vegging for about 3 weeks. The grow was successful and i never had any plant issues at all. I was just wondering if people start there ladies off on basic nutes much earlier than i did and if they feel it gives better results than waiting as long as i do??? Always looking to improve!

You can feed at every stage of the plant's life, it's the dosage that is key.

when they are clones in rockwool or soil i feed them 150ppm of thrive alive b-1 red. it's just a basic 1-1-1 nutrient. this is considered the clipping stage in my book. then when there are roots coming out of the rockwool starter cube or the plants in soil have new growth showing then i will start my 2 part nutes at 300ppm.

seedlings usually take a little longer.

Same here, I feed my seedlings abt 100ppm for the first two weeks and never had problems.
