I wouldn't be using that on seedlings, not that I grow too many seeds. I'm mostly a clone grower.

In post 16, I said you don't really need to feed a plant in veg, with good compost, you pot the plant up as the roots fill the pot.

I only plain water for seedlings. The medium is good for at least 4 weeks of veg. It says 6 weeks on the bag, but I take that with a pinch of salt. I only feed from when I flip the lights.

By Roots Boost, do you mean this?As long as your plants look good it doesn't matter
Everyone's grow conditions are different.
I use roughly the same amount as you, maybe up to 1.3 ec mid flowering.
Ive read Roots Boost granules also has slow release NPK but I can't find where I read that at the moment lol

Does it really work?
Plants roots grow when they look for food and water.

I use that, way cheaper than any of the "Cannabis" brands and does just as good. I put a 5ml spoonful in the root hole when I first plant the seedling. I have a packet here and it doesn't have any mention of an NPK ratio on the bag. AFAIK, in order to be sold in the UK it would have to display an NPK ratio on the packet, I may be wrong though.

Not saying it does not work but the job of the roots, is to find water and food, if your soil is full of food and water, the root mass will grow slow because the plant has everything it needs, the plant will grow large while the root mass stays small. (in soil its hard work for the roots to grow)

It is Mycorrhizal Fungi, it works really well IMHO. You have to use it from day one, from what I have read it can take up to 4 weeks to get going.

I use it from day one. My soil has nutrients, enough for up to six weeks of vegetative growth. If I plant a small seedling in a 17L pot (3.8 Imp Gallon/4.5 US Gallon), I can have roots at the bottom of the pot in a week.

I don't work it out so scientifically. I always figure that the companies behind any of these products want you to use the maximum possible dose, they sell more product that way. After a bit of trial and error I decided that a 5ml spoonful was about the right measure for a seedling.

Here my plant, just under 4 weeks from seed in a 2.5ltr pot, root mass is larger than the plant

What lighting are you using to get that kind of growth in 4 weeks? It looks good BTW.

A few Philips 12.5w LED bulbs

Took this picture about a year ago
Used to veg my weed under t5 and these leds bulbs are more effective, could be 70% more effective.
These leds are 50% more effective than hps (mirgo said there 1.78 )
There very cheap to buy and easy to setup, they don't give off much heat.
Used enjoy growing lots of different vegetables in my garden, so I treat my weed the same, good quality soil, large pots, soil mix that doesn't hold the water for long etc.
