I the process of growing marijuana ,Please give me some advice !

This is my growing process, hope people with experience of the plant can give me more advice.

first of all, Its germination I use a small disposable paper cup, with exquisite soil .

Then after germination long out of the first pair leaves began to use MH lamplight illuminate , 18 hours daytime,6 hours night.Growth after 7 days to move to 5 gallons of flowerpot .Soil use Klasmann - Deilmann(Coarse grained soil ) and vermiculite and pearlite (3:1:1). and a small amount of general basal (NPK14 14 14).

To grow again after 15 days ,I started pouring liquid fertilizer (NPK30 10 10).When the soil is dry to do the next pouring .

So continue to grow after a month to start with HPS illuminate,12 hours daytime,12 hours night .

After knot flower ,still use 18 hours daytime,6 hours night.use the NPK10 30 20 until maturity .

This is my growing process, if there is something wrong , please tell me.
I can improve in the future!
thx!

hey mate you don't need to post the same exact question in every subcategory , it's confusing

Seems like your have it figured out but remember it's always easier said then done good luck man on your grow.

what do you mean after knot flower still use 18/6. Are you saying that you give them 18 hours of light a day whilst in flower?

Seems I have the same question, what do you mean by that?

Yes, 18 hours of sunlight a day

^^^Close, but not quite right. In the first stage, which is the vegetation stage, you will have lights on 18/6 for your system. That's what you wrote and that's correct.

You were also correct that to move from the vegetation stage to the flowering stage you need to shift your lights to 12/12. All good there.

But for flowering you have to KEEP the lights at 12/12 until the end. You do NOT go back to 18/6. If you do, your plant will stop flowering and go back to the vegetation state, and you will not harvest anything.

So for your system it will be MH and 18/6 for 6-8 weeks. Then HPS and 12/12 for the next 8 weeks. That's it.
