Yet another Molasses question. Stinky? Anybody?

[elway07]

I have used both "sweet" and molasses and found great results with molasses in regards to added weight etc.

When I use the molasses (1tbs per gallon) I have found a pattern with yellowing of the leaves and pretty quickly. Is this normal with molasses and if so is it harming the photosynthesis aspect? When I use "sweet" alone I am finding lesser results but the plants hold a nice deep green color.
:rastasmoke:Obviously, the end result of bigger heavier buds is what I am after, but I just want to make sure that I am going at this the right way or if the yellowing is abnormal.
Thanks in advance.

Well the leaves naturally yellow towards the end of the plants life cycle.

molasses should not cause yellowing leaves.

What you are doing by adding molasses is adding sugars or carbohydrates if you want to use the agronomic term.... however, molasses overall, is not really that sweet. That is why you have the sweetened molasses! I would strongly suggest instead of molasses to add Karo syrup or even stir sugar into hot water instead.

The yellowing is most likely due to the excess of potassium that is in the molasses. It is loaded with potassium. If you don't have your magnesium and calcium correct, it is easy to go to far with potassium (in this case molasses).

It is natural to have the leaves turn and discolor, but try to watch and see why.... is there interveinal yellowing on the old leaves (magnesium deficiency)....

Thanks guys,
I had just noticed that my plant would stay nice and green until it was time to introduce molasses. I know it turns yellow at the end of it's life cycle, but I am talking about a day or so after I introduce molasses. I bet it probably is the excess of potasium. that makes sense. if that is the case, will it hurt the plants bud production at all?

Also see if the molasses you are using is 'unsulfured'.
I am not sure about the yellowing. I haven't seen that problem.
Yellowing is usually associated with N deficiency- I am almost wondering whether the added carbon is making your plants grow a little faster than normal, making them consume N faster, or if you need to add a bit more to the soil.
I can't help much with this problem- Maybe rhizome will stop by and give a hint.

thanks Stinky. yes it is unsulphered as I had read from you before I ever started using it. I guess if I can't figure it out, I will just continue as I have seeing that the final product has never left me unsatisfied. far from it actually. I have added garden lime as I always do to the soil for a mag cal buffer and it always seems to work.
I will be adding molasses to one of my plants today seeing she is a month in flowering. I have been using sweet on her with no yellowing thus far. I guess I will see after today if the problem continues. I will take before and after photos and post the before photos today and then keep everyone posted so maybe we can get to the bottom of this...

also if it is a N def.. how can I correct that? I use Fox farms nutes. the grow nutes are 6-4-4 and my flower nutes are 2-8-4 I always wait a week or so into the 12/12 cycle to introduce the flower nutes. Is it possible to add a bit of grow nutes with the flower to give it more N or is there a better way? I don't want to overload on other elements.... Thanks guys

[rhizome]

try an experiment- foliar feed one or two leaves w/ the FFGB @ 1/4 strength- see if the yellowing recedes in 24 hours.

Wondering about increased microbial activity releasing a whole shitload of NH4 sans nitrosonomas - crashing N cycle?

Or, as Stinky pointed out, you could simply be growing quicker than N is becoming available.

Pics of the deficiency would be great, as there are a bunch of reasons for yellowing, w/ N def being only the most common. I also find myself wondering about Fe, Mb...

P overload is a strong contender- you might want to run the veg nute a little longer. I stick w/ veg nutes for the first 14 days of flower.

[elway07]

rhizome...
Thanks. I will also try keeping GB longer before introducing flower nutes in the future. I actually have a few that I just placed in flower about a week and a half ago and on this latest watering I had introduced the flower nutes. That did seem to cause a bit of yellowing on those. On my big girl she received the same treatment with no yellowing. [I] am also running 8 cfl's on the big girl needing my HPS for the others.. I will water with the molasses today and take the photos. If yellowing does occur, I will try foliar feeding as you suggested to see if your theory is correct. I will post some shots today and see if maybe you can help... Thanks so much for your response..
