Maybe it needs more light.How close is your cfl?In my experience with them you can get them pretty close.
Hi, your plant has very good color and looks healthy. Once you tie the plant down it stops or slows vertical growth and promotes branch growth. Pot size can have more to do with how tall a plant will grow and more light can add bulk to both plant and buds. Most autos will stop/slow vertical growth after week five (day 37-40) so if the plant is still tied down and you have the room I would untie it.
I'm going to take your advice and go ahead and untie it, but wouldn't that give me less yield as the other bud sites will stay low down and not get as much light as the cola?
PH fluctuating can look like nute burn also, burnt tips of leaves. If your PH stays between 5.8 and 7.0 and the swings are less than 1.0 the plant will handle it, most of the time. PH control is maybe the most important factor in getting the most from your plant. Try to keep it between 6.3 and 6.7 for soil but coco should be lower I think. The plant may not have been able to get at the iron and could have caused the yellowing. The plant looks very good but very small. Do you still have room to raise the light? If the plant wants to grow up or branch out that would help with yield but at this time in the grow that kind of growth has stopped. I think you will be alright to up the nutes.
