When to switch to Bloom nutes

Right now I'm using Micro/Grow

Grow NPK : 10:5:14

Bloom NPK : 5:15:14

Grow setup:
Bubbleponics

Rez:
6 gal, 6 net pots

Plants:
2

Size:
9 inches

Age:
5ish weeks

In a max of 2 weeks I'm planning to switch over to the flowering stage, when I do so is that when I start to apply bloom or should I wait? I'm switching out nutes every 7-10 days.

I change to bloom nutrients at the end of the first week of 12/12. The first week or two is considered transition and the plants really grow a lot of roots and foliage during this stretching period. I have changed the nutrients when I changed the lights, I have changed at the end of week two into 12/12, and I have changed at the end of week one of 12/12. I have found that after one week of 12/12 and still using veg nutes, the plants have more than enough nitrogen for the rest of the stretch and show no signs of deficiency. I have done this with ebb n flow, DWC, a top feed hydro system, an ebb and grow bucket system, and with soilless medium.

Awesome, thanks for the info neon!

ive been staying on veg nutes for three weeks in. the reason, is that my veg is like 8 on n, and bloom is like 4. so far, i have noticed it seems to slow down the fadeing process a bit. i also add, 0-10-10, so the only reason use the veg, is for the n. flora nova nutes. next grow, i may go back to fox farm. at the end of six weeks tonight, one group is starting to fade. i may dos it with mg.

interesting!
