My plants is 1 inch tall in a rockwool. And the question is Should i start feeding them???

no. water or dirt?

water, hydro, rockwool, whatever u call it, i dont know???hydroponic

WHAT A GREAT SUPPORT, FRIENDS!!!! Come on i need to know when i need to switch from rain water to nutes?????? They are 1 to 1.5 inches.

I use regular water til I see a few nodes grow, then I gradually add nutes into the water. I use soil-less soil. Start with 1/4 nute formula and move up slowly to 1/2 then full strenght when they are ready. Dont rush, relax and learn from your plants. The always react to what you do, watch for positives and negitives. We're here to help.

Cheers,

I'm not a hydro grower, I stay with soil but to be honest they are in a fragile state at that age. You may want to wait a few weeks before introducing any nutes, but by all means do your homework, keep checking the thread. There are many many more experienced growers then myself, just passing on info i have received in the past. Best of luck to you man, hope your buds be strong and sweet!!!

Slow down, let her grow she do just fine with out the nutes for a few weeks. Wait until she gets a few nodes like woo says. Then go very slow with nutes.

FINALLY!!! Thanks. I will let them grow for now, but later they will have an army like schedule , and I'll make them strong like their dady!!

These things take time. If you rush things you will have many problems in your garden. Take time, think things through properly. Ask questions, We will reply. Sometimes, I wait for a few responses to make sure that I haven't been mis-informed (it happens). All will come in good time, you're in good hands.

just follow the feeding chart for the nutrients you have, you can look them up online...
