Purple stem problem

[TurboNugs]

Cut back on the molasses. At most, I give 1 tsp per gallon per week in flower. much less in veg. (1 tsp per gallon, twice a month or so)


Keep ingoing water ph stable. You can't get an accurate runoff ph with the color-coded ph test kits. The water tinting skews results, and the buffers in the soil help keep runoff ph in line.


Keep ingoing water between 6.3 and 6.8 ph.
Why are you spraying them? Why not it's just water


Since you are already giving an overdose of molasses, likely too much mg already.

If no damage, death or malformations, the purple stripes could easily be genetic.

thinking this also

Here's a link to a chart on tomatoes. I know that seems strange but I doubt if your plant is much different. In the past, people have said that purple on a plant is a result of phosphorus deficiency. If you scroll down this webpage to the chart where it says "Table 1," the first thing listed is "purple leaves." It says a lack of phosphorus is the cause. Your fert is a little short on this nute so you might consider increasing the dose or switching ferts. You'd think the product would be good for the plant, with the money you spend on it, but perhaps you have a strain that need more phosphorus or there's a problem going on that prevents the nute from being used. It's hard to tell. I'm guessing this is the problem, but I'm not an expert. Just found this on the web regarding your problem.

Thanks polishpollack good info!!:thumbsup:

I hear that a lot, but am not a believer. It usually isn't the leaves not getting/using the phosphorous, (they're still green) it's the stems and petioles, which is a major structural and functional distinction.

I use 1/4 tsp of phDown per gallon of water to correct my ph. phDown is phosphoric acid. This gives me a huge bump in phosphorous every time I water, and every time I fertilize. But, I still get those red racing stripes and purplish petioles too. Could be from cooler nights, warmer days, too much potassium, (or not enough?) light spectrum issues, lights too close (dark red (purple) is a hue some plants use as a 'sunblock') micronutrient differences or deficiencies, roots too dry, roots too moist or combinations of these and more. From what I've seen, nobody knows exactly. Lots of hypothesis, but nothing proven through biology, nor backed-up through testing by others.

No big deal, to me. Especially if that's the worst thing you can find 'different' about your crop is the purple. :thumbsup:

I'm gonna try monitoring the pH going in better with and with-out nutes. Also ease up alot on the molasses. I picked up some Cal-Mag, Clearex , Sweet and Hydroplex all from Botanicare nutes today. I got pH UP and pH DOWN to..so im ready .

Thanks for all the information/advice Rusty Trichome.

Ohhh and I have my MMJ license guys:thumbsup:
