looking good mate, node spacing is very tight but thats cfls for you, you could raise them slightly but that reduces light getting to the plants but it will make them stretch,
also what light schedule are you using, i know its to late to change now but cant remember what you said without flipping back a few pages, i know 24-0 and 20-4 give very little stretch, 18-6 and 17-7 give the most stretch for the plants, when the lights are off the plant uses its stored energy to grow roots, repair damage and in the dark the plant stretches to find the light again, its exactly why the plants stretch so much when we flip them 12-12, clearly the dark period plays a part in the plants height else they would not stretch at all during 12-12 they would just flower and grow as normal,
ive tried 20-4 and 24-0 and was pleased with the results, my autos did very poor under them schedules though, was lucky if i got 1/4oz per auto, i then grew under 12-12 with the same strain and got 2oz off an auto with 4 x 1ft bus, pics in my journal somewhere, so now im using 17-7, all my plants seem to be doing much better, they seem to be growing taller than when grown under 20-4 but node spacing is still very good, so ill see how my autos do under 17-7 this time and compare it with 12-12.
but cfls do make node spacing very tight, i used cfls from start to finish in my first journal, i found they work well if you got enough of them, i was using 23 and 30watt cfls and around 200 to 300 watt in total, i got pretty decent results and around 2oz if i remember right off one of the plants, so cfls do work and work well, but penetration isnt good so i flipped to hps when i was using around 400watts of cfls, but starting plants under dual spec hps makes them stretch more than i like so i still start clones and seedlings under cfls for a couple of weeks then go under hps for rest of grow,
your plants look nice and healthy so your doing good, autos can yield very little or they can yield well, i think light schedule plays a big part in autos as well as regular plants, im growing strains ive grown before and i know their doing much better under 17-7 then they did under 20-4, i got bigger leaves, bigger plants, but this could all depend on strains as well, so each to their own i guess, but i know i got poor results out of my kc45 autos under 20-4 and 24-0, but under 12-12 my plants where 2ft taller at harvest, they took 3 to 4 weeks longer to grow but the yield made up for the extra time, im not saying 12-12 is the best for autos but so far thats given me the best results so far, ive got kc45 autos growing again this time round so i can see how they do under 17-7,
