why are my leaves falling

Learn'in time kiddies~

That's no P def! That's too MUCH P!!! I suspect he has a pH problem also.....All in going should be pH'ed to 6.5 starting now - not a "cure" but will help!

With a NPK of 16-16-16 - the P&K are high! For many, the NPK ratio of 3 parts N ~ 1 part P ~ 2 parts K is the go to ratio.

So, looking at that. The common MG blue powder is 24-8-16....That is a ratio of 3-1-2 and CAN be used for cannabis.
TO use MG. I would run it at 1/4 strength (6-2-4) and use a Kelp extract for the minerals, B vit's and hormones. I would run a Ca/Mg product with that......It will work ok that way BUT you can't leave out any of the formula.....I would give a light leaching to the soil every 2 weeks - say a cpl of cups of run off....At the next watering I would water with a nice Bio tea to keep the soil soft and alive..I would make sure that all in going was 6.5 - 7.0 ! IF the plant seemed to need "more"? I might go up to a 1/2 strength feeding, once every 2 weeks instead of a 1/4 strength one - all other "feedings would be the 1/4 strength.......I would do every other day waterings and use the "feed - water - feed - water" method......You would have to adjust the "amount" of liquid you water to match an every other day sched..

THAT, is how "I" would run MG

I said lockout, meaning p def due to too much P.

 

[Olive Drab Green]

16-16-16? Then phosphorus def is more than likely being caused by lockout. Or it is mag deficient as well.

See? It's not taking anymore in because there's too much.

That is a very interesting book you have there Dog! Looks like a NICE "learning tool" for those new to any house plant!

You should link a sales point for that!

I want one Just to see what it has to say......

Maybe some but, I believe it's being cock blocked by a low soil pH situation - common with MG use.......I would do a light leach w/water and a Ca/Mg, pHed to 7.0......That would help no matter who's right about the P......Still the pH problem shows...

Ahhh, I see.

 

[Olive Drab Green]

I wasn't disagreeing with you. I was just showing that I was at least thinking in the right direction, albeit a little short of the cause.

Damn - I wanted that issue! Have to find out if you can get back issues....

Yes nice, thank you .

Hi guys, i just want to share my plant treatment process, I've transplanted it into a bigger pot, and i stopped using the previous nutrients liquid untill i found a very good nutrients liquid with 7,5-10-10, and the plant seems liking it.

The leaves dropping has been stopped and the color of the leaves are starting to turn green again instead of yellow, i just add 4 drops from the liquid into a 0,5 liter of normal water.

I trimmed the damaged leaves and i smoked it : ). Does the dropped leaves will grow again?

Unfortunately, those leaves will not recover, but your plant is recovering according to what I'm reading from you.

Oops, so the leaves will not recover ok lets wait for the new leaves to grow.

Regarding the flowering schedule should i change it to 24 hours lighting as per the leaves are still small and in growing process ?

I started the schedule of flowering stage just last week.

 

[Olive Drab Green]

Flowering is always 12/12 or less. 24/0 will cause you to veg it longer or reveg it.

 

[Olive Drab Green]

You probably could reveg, but it's probably not necessary.

 

[Olive Drab Green]

Pics today?

 

[Roy1212]

Even if there are small leaves? Are they going to grow in the flowering stage 12/12?


Sure I'll take pics and I'll post it in a minute.

The buds will grow sugar leaves, so any leaves you are missing, chalk it up to defoliation.

So it's ok then i will continue 12/12 schedule with the same amount of nutrients, and I'll see how it goes.
Thanks dude

I'' add my opinion here though I'm no expert on this kind of things.

Couple of main reasons why green leaves would drop
1. Shock
2. Over watering
3. Under watering

I think the issue is more likely poor plant transpiration and here's why.

Though It seems your watering schedule seems normal (not over watering), without air circulation, you restrict your plant to transpire H20 during photosynthesis which is critical for a plant.

Why air circulation is important? The importance of your fan (and the myth of making stem stronger bs) is to provide air circulation. But why air circulation is important?

When plant transpire they create a layer of 'thin air' around the leaves that is full of moisture. Think about it for a second. Even if your RH reading is normal, without air circulation, the air around the leaves has very high RH. This is a protective mechanism of the plant out in the wild to prevent rapid water loss.

If you dont move this thin layer of air around the leaves, come to a point that its preventing the plant to release the necessary amount of H2O and all your watering is just accumulating at your most mature leaves and could cause premature drop or really brittle leaf stalk.....just like over watering.

This is the reason why we need a fan inside our grow area and not because it would make your stem stronger.

But again, it's just my opinion.
