adding pk in a DWC bubbler system

[mitch1075]

can anyone advise me on this, when would i add pk when growing a short flowering stage plant ( 50 days flowering),, in a DWC bubbler system????

Short answer: when it starts to flower, probably about four weeks from seed or so if it's an auto. Maybe two weeks after switching to 12/12 if it's a photoperiod.

As you probably know, you shift the fertilizer balance more towards P and K in the flowering stage. Are you using an established fertilizer, like a 2- or 3-bottle solution? If so, why not just go with the recommended weekly regimen?

If you're using a more typical garden fertilizer, then I guess you'd just gradually shift from the high-N version to the flowering version.

If you are of a scientific bent, you can work out the exact NPK levels of existing cannabis fertilizer regimens from the numbers on the bottle and the dilutions and ratios.

It would be easier to type this if I had not been bitten by the white widow an hour ago. 8-]

This is my nute schedule. You'll see at the bottom that I have a time line for 7 week strains. It's for Coco, but the time line is the same. I phase koolbloom in during the second week of 12/12.

It must have bit you pretty hard!
This is far from your typical response to nutrient questions!

Yeah typing under something like the Widow can be hard.
