when i start seeing roots from the siol of the clones are they there own little plants now?
Yeah once they develop roots they are rooted and are there own little plant. Around 2 weeks after they root you'll start to see growth.
If so how big to expect them to get ? Should i/or could i start the flowering now or what a few weeks
Thats up to you. Once the growth starts they will grow as much as you allow them to. You can start flowering as soon as they root if you want to, you'll have smaller plants. If you want bigger plants let them grow in a veg cycle for a while.
are my clones as old as there mother or should i look at them as if they are seedlings?
From when they are cut until 1 week after they root I keep mine under a single CFL. While the roots develop the clone doesnt need alot of light. After you clone a few times you'll see that once the plant roots and is ready to start new growth it will kind of perk up, almost like its asking for some real light.
As far as nutes go I let them root and wait for 2 weeks before i give them a 1/2 strength feeding. After that I feed them like an adult plant.
Hope that helps ya, good luck on your grow
