What physical differences between pre flower and full flower besides more calaxes and pistles.? Having trouble telling exactly when they go into full flower.

I would say that once you see significant pistle growth (in clumps the size of a dime or bigger) on 80% of the branches then she has reached full flower stage. It seems like that is about the same time that the significant stretch stops as well. Typically 2-4weeks after the flip to 12/12 in my experience

also when growing from seed, the earlier you begin the flowering process the longer it will take to see flowers. there has to be sufficient growth before flowering can be sustained. the term "pre-flower" is used to describe the single calyx and pair of pistils that grows at the internode, when a female plant become sexually mature. this single calyx/pistill's never becomes a growth site though.

would this date, about 3 weeks after flip to12/12, correspond to the change in feeding from Transition to Bloom?


GH Flora series (grow, micro, bloom)

VEG: 3, 2, 1
- - [12/12 light]
Transition: 2, 2, 2
- - [3 weeks of 12/12]
Flower: 1, 2, 3

thanks

420freind, not for me. When I flip to 12/12 I give one feeding of the transition strength, the next feeding I go to flower. I am in soil hydro may be different.

it has a lot to do with knowing your strain. my southern lights stops stretching at 7-10 days. so in this instance mr1's method would work perfectly. but a strain that stretches for 14+ day's you might want to run the transition nutes a week longer. you don't want to cut off the plant's supply of N when she's trying to rapidly create flower sites.

Right on Shortbus.

excellent information.

thank you!

in my current situation (bag-seeds) I don't know so I'll stay in transition nute and just watch for a slowdown in growth and then swap to full bloom
After this grow I will be running 2-?? generations of White Siberian so I will research first and then note the pattern on the first run.
