Im stumped...

[randy954]

Ive recently started to notice certain plants are turning yellow, well alot of the leaves are turning yellow. Theyre the same strains all getting fed the same regiment from my drip system. Heres what im giving them currently

1 tsp/gal flora grow once per week
1tblsp/gal flora micro twice per week
1 tblsp/gal flora bloom twice per week
1 tsp/gal kool bloom once per week
1 tsp/gal protekt once per week
1 tblsp/gal cal mag twice per week
Most of my plants look very healthy but it seems like a group of plants are starting to yellow drastically. Ive flushed twice and ran ro water the past 2 feedings.

Im stumped and cant figure it out!! Any input would be great.

Getn that time

 

[randy954]

But why are only some of my plants doing it?

I thought this thread was guna be a penis joke by the title of it ..........anyways that's your plants fading and if your using a tank and drip system as I do myself some plants can and will get more food if you don't mix your nutes well and they settle/concentrate in your tank ......also remember just because there the same strain there all individual plants .......but I wouldn't worry much that's what happens this time of year it's fine .......my plants look rough at harvest but I also like a good fade ......GL

They look good to me. You dont need all those fan leaves. I take most of mine off because my canopy is so dense it wont let air through.

A healthy plant shouldn't have a lot of yellowing leaves and you have a LOT. It looks like you're not giving it much N from the list of stuff your feeding it.

I find it strange that people say things like "You don't need those leaves" when the leaves are the connection between your plant and the sun. There is a common thinking that leaves are supposed to just turn yellow and fall off during flower which makes no sense.

The plant is at the end of it's life cycle!! It's using nitrogen to produce buds. It's perfectly normal on almost all strains!!!

It makes perfect sense. The plants store energy in the leaves all year and now the plant is using up all her stored energy to try and push her flowers a little harder so they can hopefully catch some pollen and she can finish her life cycle. If the leaves are yellow and fall off with the slightest pluck then there finished and it's best to remove them because dead foliage is a great place for pests to move in.

So lets look at this logically. You both are saying it needs that nitrogen to produce buds and is resorting to taking that N from its own leaves to "produce buds" and "push her flowers a bit harder"

Rather than forcing the plant to use its own "reserves" to acquire this Nitrogen, why don't we listen to what she's telling us and give her some more N? That way her fan leaves can stay green and keep doing their job (photosynthesis) while still getting these nutrients that we all agree she needs.

How close are you to harvest? Leaves fade in late flower as the buds cannibalize the energy from them.

You don't need N like that in late flower, and if it's 2-3 or so weeks out, letting it fade is the better idea. It's common and natural.

 

[Kidbruv]

But why?

The plant seems to really want it if it's taking it via cannibalism.

Because that's just the way it works. Like, it's kind of cleaning itself out of the last of its stored energy because this is its final push. N is only used up into midflower to accomodate the stretch, then you drop it as low as possible. Like, 1 to 3 in organics, those are my parameters. You don't need to give it more nitrogen than it needs. Honestly, it alters the bud taste and it leaves it full of chlorophyll if you don't let her fade out.

Try and see what happens!! For one thing you shouldn't be introducing a whole bunch of nitrogen at this point of the game. That's why most bloom formulas hardly have any nitrogen in them. Some zero most people over do it at this point of the game.

Easy, man, I think he gets it now.

 

[Kidbruv]

I realize that a plant's nitrogen requirements are less during this stage, but it's still a balance and some of those plants from the OP look seriously starved.

Just late flower fading, Little Cannabro. Don't sweat it. It's the way it goes.

N Is used in chlorophyll production. Late In season clorphyll production stops and the chlorophyll built up in leaves begins to break down. Natural N uptake by the plant slows and then stops. So she doesnt want or need it. Part of the break down of chlorophyll is to do with the angle and spectrum of the sun in the fall. You continue to feed N you will get larfy buds that taste "green" and smell like hay.

Being a northern grower myself I have tested the theory of keeping a plant green til the end vs letting it fade out. And this was my findings...

The ones that stayed green had a much slower flowering time by almost 2 weeks.
They had smaller buds, and had much more problems with that "hay" smell.

The ones I let fade naturally had two to three times the bud mass, finished quicker, and kept the bud smell. Was over all just better weed.

When you have to deal with rain and frost and cold temps I much prefer to get them done as fast as possible. Who cares if they don't look as pretty

 

[Kidbruv]

Thanks for the responses. Very helpful to read some good reasoning and first-hand experience.

I've seen and admired plants from both you BC and you Gangagirl so I put a lot of weight onto what you both say.
