No, the cotyledons are the first round fake looking leaves. Then you have the single bladed marijuana leave. Every single seed I have grown has them so I know this isn't out of the ordinary. THe next set of leaves goes to three blades and then set after that begins its full five blades. Thats the same way it goes every time for me. Keep in mind, I'm talking about from SEED.
That's correct. The round "leaves" are not leaves, they are food storage organs aka endosperm. That is not considered a node regarding my method. As you stated, the rest of growth is the progression from a juvenile stage to adult stage.
No. Try to understand what the plant's actual anatomy is regarding plant parts and their functions and how plant hormones control all plant functions and processes. There are dormant buds that reside within the axis where the leaf petiole attaches to the "trunk". These are capable of output. If underground, they become roots, if above ground, leafsets with petioles.
Thanks! Good to know. Thank you for helping me to further understand how the plant works!
Sounds like you didn't give them enough light. Seedlings are fragile but stand on their own under normal circumstances.
My feeling for the development of strong stems is plenty of light and adequate P. What is "adequate" you say? Something like a 10-10-10 or perhaps a 9-3-6.
Phototropism, or the plant's response to a point of light by elongating/expanding the cells on the shady side to tilt the plant material into the light source. Hope you don't mind me getting anal.
My theory to using fans to supposedly strengthen stems is based on plant damage like you alluded to with the muscle thingie. Kicker is to create stem fissures which will callous over you need to have hurricane force winds before anything will happen, and even then any positive benefits is debatable. (One thing that is not debatable is that cannabis forum paradigms die hard.) Chances are you'll just end up with a broken plant that you either have to stint or shit-can. Trust me, I live on a hillside that gets 20-40 mph winds quite often. All it does is tear stuff up.Similar concept to the fan wobble.. IIRC UB doesn't actually consider fan strengthening effective.. Personally I'm torn on that one since I get the feeling that cell growth likely can't keep up with other cell destruction if they never get a chance to rest (kind of like how your muscles actually grow after workouts and during sleep, the workout itself actually destroys muscle fibers).. But regardless, that will help protect you from stem rot, just don't over do it, what doesn't make them stronger only kills them..
