Short direct sun light hours, which supplements to help

[cfl...KING]

So I've always been an indoor grower when it comes to larger grows, from a few 100w cfl cab to 3-4k watt rooms an everything in between. I've encountered bugs an heat issues but never had this issue before. I have 4 plants in 7gallon pots outdoors on a porch. I knew based on sun angle changing light was going to end up being an issue. But no where near this bad. By 5pm they are no longer in direct sunlight an it's only getting worse. A couple of them are out of the sun by 3pm. I haven't grown in about 5 years an alot of nutes have changed. I was even considering Humboldt gravity but seen it was pulled of the market. They haven't even started flowering yet an only seeing about 10hours of direct sunlight. Which is only going to be less an less. They are beautiful plants almost 5ft tall, 3ft wide bushes with pretty tight nodes, they haven't started to stretch yet. (Ps my house is in the way of the sun not a tree or anything I can do anything about).

I planned on running all canna nutes thru bloom which is what I always ran indoors. But I don't want to dump a bunch of money into these plants to get some airy leafy nugs. Moving them isn't an option. I'm open to running PGRs or any nutes that will really help specificly for the lack of light.

Anything more than 5hrs of direct sunlight should be fine.

I don't have experience growing outdoors, but I believe 30 DLI is a good average. I got this info from bruce bugbee. It's not as accurate, but your cell phone may have a lux meter built-in. You can convert lux to get your dli. The problem is unless you are out there all day taking measurements you won't know the total. I think bruce said it can flower in less than 30 but you start to see significant loss in yield. I have been helping a neighbor grow outdoors and my meter is saying about 1500 lux which when converted is not where near 30 DLI. She has flowers but they are airy. She also doesn't get the concept that in its dark period it need to be dark. There is a porch light that is on a motion sensor that turns on. It's also been the worst year to grow outdoor this year. Too cloudy and rainy. Not sure if this helps or not. Best of luck to you.

If you are getting 10 hrs of direct Sunlight you don't have anything to worry about. A cannabis plant can live on 6 hrs of direct sunlight a day and still flower and make buds. Easy on the fertilizer when the lighting is short. Start with 1/3 of the fertilizer recommendation.

You might be over-nuting the plants.

If they're getting fewer hours of intense light, they're growing less and eating less.

No need to feed them extra.

If your getting 10 hour direct sunlight you have nothing to worry about (at least in that regard).
My "outback" plants get about 9 hours direct light and were 8' 8" on Aug. 31, and flowering for awhile.

Green Crack outdoor, @45N

So, I had made a couple/few posts in other "general" outdoor topics, but I thought it time to start my own thread. Anyway, Green Crack, Apr 21 = day 1 (can show). They went outdoors on May 21 for good. Today Jun 15, Day 56. In tires on ground 38" tall. In ten gallon containers, on the roof...
