The flowers as far as size goes are looking to be a week or so behind. I think my uncle should pull a half hour of PAD light (on time) and add a half four of SID. Sal what do you think?
Depending on the spectrum of the Orange incandescent light replacing a Red Incandescent light, you may either be getting a bit of Blue light contamination which will proportionately reveg the plants morphology as the Blue level increases, or you may be getting more or a PAD Time Factor increase (decrease in overal equivalency SID time) due to the added non-Far Red light in the Orange lights spectrum (likely to some extent).

Since your system is HPS wattage dominant for yeild, it sounds like you lean more towards swapping SID time for PAD time, as opposed to swapping PAD time for HPS time. So yes, that would be a way to increase your overall SID equivalency time.

Swapping one way or the other depends on what kind of trade you're looking for, such as overall bulk vs. grams per KWH or trichome/THC production. The total SID time experience by the plant determines WHAT genes are executed, but the total PAD, SID and HPS/SAL (Standard Artificial Light) times and wattages determine HOW and HOW MUCH those gene commands get carried out.

With what you are calling "Banana Leaves", it looks like some vegging genes are getting executed and the Orange spectrum does make the plant think the night time is a bit shorter, but Blue signals would be producing veg genetic signals as slight PAL (Day) time contamination during what would otherwise be flowering signal PAD (Night) time.

I'd have to have a Spectral Power Distribution (SPD) graph of that particular Orange Incandescent lamp in order to tell you for sure what is happenning, but an increase in the plants percieved Night hours would a minor adjustment, and I think that some Blue light contamination in those Orange Incandescents is a likely problem.

Since there are no standardized systems for defining "color" or "party" bulb spectrums, it's very hard to recommend lamps by mere color designation rather than their actual spectral outputs and if they have "light leaks" past their filtration coverrings.

The Orange/Yellow bulbs that are clear enough to see the filament in detail, tend to have a slight Blue leak past the filtration coverring, and the effects of this are relative the intensity of the Blue light leakage. A slight Blue light leak has a slight effect, while a more intense Blue light leak has a more intense effect.

The relationship of the primary and secondary signals from a light spectrum, represented in the plants genetic responces, is what Rauber refers to as Genetic Bandwidth (GB) or Gene Time Bandwidth (GTB), and it can be viewed as positive or negative depending on the results, but Rauber prefers to eliminate GB as much as possible to optimized targetted genetic execution, such as Trichome/THC development.

If you have some veg gene signals thrown in with your flowering gene signals it may produce larger leafier buds, which could be considered good if you are just considering final bulk of your yield. If you wanted more trichomes and less leafy buds then it might be considered bad. It's a matter of preference.

The Bandwidth thing can work both ways to, more bandwidth could mean more leafy yield with trichomes or trichomes with earlier harvest, depending on which side (earlier/later) of the trichome genes the bandwidth falls more. Rauber prefers to target one specific gene zone target for execution without hitting neighboring genes (earlier/later) in order to avoid secondary execution results (such as leafier buds or yeild losses due to an earlier end to flowering).

BG exists in nature, and a little doesn't seem to hurt anything, but in excess I personally consider it a bad thing, since it ends up producing more intermediate/indeterminate results.

I hope that's not too much more information than you needed. Genetic Bandwidth reduction is one of the final things addressed in Raubers work, but it is an interesting concept to consider (sort of a higher level of fine tuning).

Take Care, Sal.
