Need advice new grower

My plant is around 5/6 days old from germanting it's about 3.5 to 4 inches big the stem is skinny and got 2 petals and first 2 cannabis leaves but the about 2 cm big there in a jiffy puck and got clay pebbles around it I'm using a hydropolic system and my lights about 6 inches away from my plant I want to no should I turn my system on and can I start feeding them I leave my lights on 24/0 I'm using a 125 watt light aswell and it's just one plant and help or advice I will be posting pics up later

Why any organic material in a hydro?

Way do you mean

What do you mean

Pic? is the light a cfl? maybe drop it or don't raise it anymore...just dont let her stretch for the light too much. What kind of system is it? You should have pure pH'd water running through it now keeping it most. Do you have a timer? run the feeder for 15 mins every hour, this will keep it most and not over water. Then adjust from there maybe give it a two hour break if it shows signs of over watering. I'd recommend wait for second leaves development before implementing any nutes as to not burn it too early. A cal mag + would be ok being without soil, but very light and if you want to add grow, you can but go with 1/8 the recommend dosage. next week, 1/4.

im sure you did some research but some major things to watch out for is Ph, PPM, and lighting. I ph my water everyday, only takes a second. Ive heard that your not supposed to nute until weed 2 but I start it very very light on the 7th day. since your using cfls put that bitch as close to the plant as you can get it without burning it. I put my 125w like 2 inches from the tops. if you don't already get a small desk fan and have it blow through the light and the tops of plants. very light, it will strengthen the plant. and I always recommend the 18/6. the plants like to rest a little bit. ive heard that the roots will expand during dark period Idk the truth behind it but plants seem to do better with a dark period. if youre using RO I recommend cal-mag.

That sounds a little tall for 6 days old. I'm betting its stretched. That's something you want to avoid. Get light close but control the temperature of the area with good air circulation

the jiffy puck will rot and be bad for the setup, i think thats what harley means.

put system on they need water and air and very very very liittle nuts do to you dont have any in the water and there young
