Hi All.
I was wondering if anyone could maybe walk me through the seedlings rule of thumb growing tips. I seem to really screw a seedling up one way or the other. How many hours of light do they get when you plant them after germination 14 ? 24? How tall are they before you use any nutes? Do I use water only when very young? At what point do I snip the tops and where?
I have tried them in soil and in hydro. I seem to damage them at some point when there young. I do just fine with clones but seedlings seems to be a very sensitive situation.
Thanks For any help,

Welcome to the forum Dave
18/6 or 20/4 is a common lighting regime.
You need a soil with no nutrients added to it.
None of this added feed that lasts 1 month or 3 months, it will kill your seedlings because every time you put water in the soil it will flood the soil with plant feed.
MJ needs no feed for 4 weeks, none at all, so many people make this simple mistake and wonder why they have struggling or dead seedlings.
Over watering is another killer, a seedling will only need watering once a week, maybe longer.
A seedling has a single root that will eventually grow other roots from it that will stem out from the single root, if you have a sodden soil then the root will have no need to grow in search of water.
While this happens the single root (they are called tap root) actually drowns because another essential error people make is not realising that roots need air to breathe, yup, roots breathe.
So between watering's the soil needs to dry out, MJ originates from arid climates and still needs to think it is in a dry environment.
Fluorescent lights are perfectly fine for young seedlings whilst they get established (grow a root system) then later on you will need to get better more powerful lighting.
3,500 lumens per Sq Ft is needed for seedlings then it goes up to 5,000 lumens.
