The NPK are a little high,,It would depend on the media you use to grow in. Soil, what soil?,,,but, light use (kind of under fertilizing) may make that work out. Still, it's geared to something else, not Cannabis.

I think it's some of those tomato soil bags mixed with composted cow manure , I wanna use it because my plants are growing so slow, about 5 weeks from sprouting and their stems are thin, however they have 7-8 nodes except this one , it's a og kush

Using an EC/PPM tester, you could mix in water for use in soil or hydro, but those numbers seem a little high for starters. Only using the tester can you dilute to a known amount and work up from there. You also have to know what is already diluted in your soil, so PPM/EC tests of runoff along with PH tests will help a lot.

Your plant look fine. No signs of deficiency at all. More food does not equate to faster growth. Not sure how many times you need to be told this. You are going to end up killing them with concern. Just water them for awhile and watch them grow.

You're welcome. And I would go ahead and get them under the MH right now. 18-20 inches above them would be about right. Give them another week of veg then flip to 12/12.
