No worries and thanks for your kind words, but I'm just a noob at this too really. Did quite allot LST on Autos when I first started tho. There were two blue cheese, but one wasn't ready for LST. I ignores the voice in my head that said 'let it grow dude she's too young' and listened to the other voice that said 'Bondage is fun, tie her down.'
Well I tied all four limbs down, put the pot back down in the tent and somehow pulled down the main line connected to all four limbs and three just popped off. Couldn't help but laugh. My best advice is wait.
Wait till seed or clone is a good six nodes with a nice root system before you top. Allow the two main branches to grow again until it is around six nodes again be for pruning for four. Top a healthy established plant and you barely see a break in growth, versus prune early and literally watch naff all for a week.
I'll share an awesome tip I use throughout veg. It's a milder form of supercropping and I use it to slow down main stem/cola growth and to beef up the stems.
I pinch the stem between thumb and forefinger making sure my nails are not going to accidentally top the plant.
I very lightly squeeze the stem.
Now hard to explain what im looking for but ill give it a go. Imagine a human leg with two braces for support, they are parallel at the side of the leg. Now imagine the stem of a plant, inside it, running vertically up, are two braces either side.
When I lightly squeeze the stem I do it all the way around until I can feel my thumb is on one brace, (feels like a small ridge in the stem, slightly harder) and my forefinger on the other. Now I squeeze harder till I feel the stem pop, and thats it. It slows growth for a day, and after a while a knuckle forms and the stem thickens up.
Too many times I've supercropped and its gone to far or a branch breaks off, this has all the pros of cropped with as far as I can see no con.
