Couple questions..

Heres a few different pics from one of my plants... also some new growth is coming out dead.... and blackish... its about 12 days into flower
any help is appriciated.

Pic 4 is a different plant and the whole thing has like a powdery white residue all over it..
Any idea what it could be?

pic 5 is a clone I had a thread about my clones with lower leaves turning yellow then dieing. My clones are in foxfarm ocean forest soil so I was thinking maybe its from the nutrients in the soil.. I know its no big deal but any input will be taken into consideration
Thanks DOE

What are you feeding it. PH?
It could be a number of things. Without this info, we can't tell. It could be your ph is off. It could be a nutrient deficiency. It could be over watering.But I doubt that.

Im have only fed it one cap of Foxfarm big bloom and a cap of seaweed extract.. to a gallon of water I didnt feed throughout veg.. the PH of the feeding was really low and I didnt have any PH up to fix it.. it was around 5.5-5.8.
Id say its possible it could be overwatering.. but not anymore... and everyday i see leaves worse and worse.. and its not just one thing its several different things. new growth is coming out dead... leaves are yellowing with brown splotches and a few leaves are curling under..

Oh BTW I tested the ph of the soil and its about 6.2-6.6 or so..

If the new growth is growing bad. It is probably a nute deficency.
Or the ph. But the ph sounds ok. Maybe the low ph is locking out some nutes. You should be feeding them a veg nutrient that is high in NItrogen.
And try and get the ph up to 6.5-7.0 especially for veg.:thumbsup:

hmm.. Hey john.. can you give us a wide shot of the entire plant,,

actually a bunch of pisture of the plant that is flowering.. that is the pant that sounds worst off and needs immdiate attention..



thanks
: )

yeah no problem and btw jdog the plant is flowering not vegging

Here are some wide pics and a pic of some new spots.. that I think just came up recently..


For the most part I think they look really healthy Its just got a few FUCKED up leaves hear and there. I just dont want it to get any worse.

Could all this have to do with the split down the middle?
For those of you who dont know this plant got cracked right down the middle of 2 nodes. And it hasnt really grown back together after taping it up

You need to remove the dirt from between the split -- it's going to be very difficult for it to merge when there's soil in the way.

For some reason I feel that may be doing the turgor pressure a great deal of pain.

I followed the other thread, as did Garden Knowm. You should try cleaning the wound up very good, and if the split is still moist it should merge. If not, try roughing it up just slightly; then spraying the area with a water/SuperThrive mixture; then tape the two halves together and leave it be.

It could be interference with the nutrient uptake, so essentially a lock-out of an unusual kind.

But still, there seems to be something else..

There isnt any dirt in there anymore and it is dry as hell I dont have any superthrive right now. and Ill go ruff it up a little and tape it back up right now

Careful with it, then. It's sensitive, so be very selective of the areas you decide to open up. And by open up I mean just barely shave off the dried parts on the corresponding halves until the 'sap' comes up.

Remember, both halves that meet must be moist with the blood and viscera of the plant, and then moistened with water before being taped. This time, make sure it's tight, but not so tight that it restricts the stem's nutrient/water uptake efficiency.


..Sorry, there was no gentle way of putting that first part. I couldn't help myself.

lol that was exactly what i did too i got a pair of scissors and put it in the two halves and shaved a lil off then I sprayed it then taped it up

LoL

I was kind of visualizing a sterilized exacto knife, but that works I suppose.

lol
woops

she will be fine if not all 16 of her babies will but the majority of them will be out doors I wanna see how this strain does out doors and how big she gets :)
this plant was actually grown out doors for the majority of her life. I should be taking the children to their new home sometime this weekend or next

Does anyone know what kinda defficiancy causes a white powdery substance all over my leaves?

Can you wipe it off like is it mold?:smokin:

A white powdery substance?

I don't know of any deficiency that'd deposit matter on the leaf's surface -- no, it's not a deficiency.

Are you spraying anything on the leaves -- foliar feeding with any diluted nutrients, maybe your water's hard?

Although, as Krogith suggested, it sounds oddly like a mold.

No I dont foilar feed But I have.. and you can sorta wipe it off but its stained onto the leaf under the powder..
Note:if you look in the 4th pic of the 1st post you can sorta see it..

Ah, let's try to figure this one out..

When did you last foliar feed; and what did you add to it, if anything? Water with a higher EC can burn/bleach spots on leaves under lighting. This can be attributed to 'chemical' burn under particularly hot lamps, or even just the prism of light the water creates and concentrates on the sections of leaves the water's beaded on, and that doesn't require any nutrients in the water.

The powder, I think, might be lime deposits from either hard water; or nutrient deposits from when the water evaporated, leaving whatever you might have added behind.

What kind of lighting are you using?

Im using a 400W HPS I foilar fed about 3 times a few times with just water and once or twice with some either foxfarm grow big or big bloom. Sigh... I cant even remember.. I also dont remember if it was tap or my R/O water

Also I didnt start these plants myself they were all given to me.. but it doesnt make sense that it would burn one and not the rest ya know?
Is it possible it could be from his soil? But then again I dont think they were like this when i 1st got them. also the majority of the plant has 3 leaves except for the new growth..

once that scab has formed they won't grow back together. you need to tape em up as soon as they break while the wounds are fresh. i suggest splinting the sickly half to relieve some of the strain of supporting itself, which i urge you to do anyway once you begin flowering.

Hm, it might be the soil, then.

Some of the first pictures you posted with the plant's fan leaves curling inward and down told me it could be over watering, maybe even improper soil aeration. The soil has to be nearly bone dry before watering again -- Mojave desert, cremated man's ashes dry.

The plant has to be just on the verge of getting to wilting, but not so much that the turgor pressure is causing the plant to noticeably go limp.

What kind of mix do you have? You said something about having a clone in Fox Farms soil. Are you using that, and if you are did it include perlite, or did you add any?

Another likely possibility is the soil has got too much food in it. Do you have a TDS meter, maybe something that measures the water hardness?

Yes it had perlite and I added some aswell. I dont have a water meter and I will put a splint on her tomorrow thats a good idea thanks.
