That's actually an interesting question. A grow a lot of veggies and lot's of leafy plants do it when they "go to seed". Like leaf lettuce for example. It grows nice and short and bushy but when it gets mature it will throw up a big spike stalk with a few leaves and the flowers.
You say you use it the entire grow.How do you use it?Mix it in the soil,teas,top dress??As per directions on the bag?I use the garden tone 3-4-4 as my flowering nute or after stretch,for veg time I just feed with a little MG 30-10-10.Always with a little Epsom and Blackstrap.
Per bag instructions, mixed into lime adjusted peat, perlite, and a bit of EWC.
Im going to take a wild guess that you don't understand what role P plays in Plant nutrition .
Yet, when candy kush was placed in a wetland with tight surrounding native plants last summer...they stretched to high heaven. I must have topped those a dozen times to keep at a 5' ht. Even the ones outdoors without any surrounding plants had the same results. We had a warm and dry Summer/Fall, so perhaps temps cause the stretch.
What's this supposed to mean? Phospate does add to the stretch of plants, it's been studied and documented numerous times. People on pot forums seem to think it's nitrogen that adds to the stretch when that is completely false.
I'm going to take a wild guess that you don't understand how over-rated and over used P is. The P contained in a 3-1-2 is more than enough for any kind of plant much less cannabis.
I've grown Indicas and Sativas next to each other in my closet. Strain is huge in the stretch, at least with my indoor experience. But, I've noticed that the Sativa I've grown (same strain) has grown/stretched differently in each grow. I think nighttime temps have a lot to do with the actual, total stretch. Warm nights lead to more stretch. Cool nights lead to less stretch.
Lemme take some pics of internode spacing today...sativa nodes spaced half the distance of indica. Both were cuttings started at the same time, both topped once and vegging in a cool basement at the moment. All in same medium/under same lighting. Even the Malawi from seed isn't stretching nearly as much as the candy kush...which to me seems backwards.
Here is a picture of my current grow. Sativa is on the right and the Indica is on the left. I've topped this Sativa, twice, and the Indica once. Right now, after 4 weeks of flowering, the Sativa (at the top towers) is 55" and the Indica is 22". They have been grown together since day 1.
