Help please! Leaves dying quickly

Hi there guys..

my plants are suffering from something that I cant find out the reason...

Those are White Widows, and they are in a 70% Perlite / 30% Sunshine Mix #6.

Im feeding them with the FoxFarm line..










Please if anyone can help me!!
Sorry about my english!

Thanks to you all!

no one to help me?

i have that same problem along with using the same line so im curious also

necrosis? that could be... no clue man. hope someone helps you because ive had this before and never knew. id say in my experience though its a p or k deficiency.

Have you ever grew with this medium and nutes combination cause I'm thinking it's one
of them or both that's a lot of perlite I like using 100% ffof or whatever
I'm using whenever I tried mixing it with shit it f'ed up your growing with
cfl or what the plant looks a little stretched how much of what your feeding
would be helpful knowledge in telling you what to feed it~

you got bugs? it seems so scattered.

looks like it is a problem with fan leaves but not on the new growth. could be nitrogen moving to the new growth, how do you irrigate, drip? how often? what kind of light how close are they, more fertilizer isn't always the solution. Last resort cut off the damaged parts of each leaflet, if it keeps getting worse you still haven't found the cause. For pests look on the underside of leaves for dirt or microscopic bugs on a piece of white paper, if the bugs are big enough to see with the naked eye they arent as bad usually. Is there a fan? you need air moving , that plant looks droopy.

i forget what that is, but it doesnt look Really serious..

besides you are in flowering, losing fanleaves is regular (ive got no fanleaves at the end (plump juicy buds though)

only thing that comes to mind, might be trying feeding it straight water for a day or 2, flush it bit, see what happens.

but

if all the new growth is fine, then there isnt really a problem.

and there are knowledgable folks online that would know what that is, so you could just wait abit more.

(unless ya get lucky,you really have to wait at least 1-2 days for the really good answers (even people without a life need to sleep (not to mention if they actually have a life lol))

looks like a Cal/Mag deficiency from the pictures...Dolomite or a combination of garden lime and Epsom salt will fix it.

Hmmm...I would check your ph of the water you add as well as the runoff and then adjust accordingly. Looks like a ph issue of some sort to me..

Thank to all you guys for all the answers!


im going to give you a bit more information about my plants...

as I said im feeding them with the foxfarm line.. and Im following the Feeding Schedule from the FoxFarm website..
http://foxfarmfertilizer.com/FoxFarm-Soil-Schedule.pdf
but having the PPM a little under of what they sugest...

I guess my growroom has enough ventilation, but as I live in the Brazilian Northeast and the temperatures here are always
high (between 26 to 32 degrees Celsius), the temperature insinde it is almost the room temperature... when the light is off it goes around 27 - 28 C , and with the light on it goes to 32 - 33 C..

The light Im using is a 250W HPS with a Cooltube.

I know some will say that the temperature is quite high.. but I have grown some plants before without having any trouble...




Also I guess im having trouble with my pHmeter.. if so the ph is probably completely wrong... I ordered the calibration solution for it last week but it might take a week or two to arrive here...

So I guess until I have it in hands I will only water my plants with plain water...

If its a Cal/Mag deficiency, would be helpful if I spray on them a solution of water + epsom salt??



Just to conclude and make sure Im doing it right.. in that kind of medium (SUNSHINE + PERLITE) what is the ph im supposed to feed them with??



Again, thanks to all of you!

PeacE!



PS: Tomorrow if I have time I will take some new pics from the whole growing area...

thats some nute burn. my friend give it a flush and feed it only ph treated water

You are looking for around 6-7 it isn't quite as exact as hydro, and doesn't need to be... anywhere around there... and some plants like it lower, and some don't seem to care...

and it could be burn...but the weird stipling on the leaves makes me think calcium deficiency due to PH...I notice that Fox Farm soil, and really any organic nutes are really alkaline...and MJ is acid loving so PH down is a friend indeed...and you know what i think I like better than PH Down...just vinegar...

a nice spray of Epsom salt would be a great idea, and the dolomite will also buffer your soil if the Ph happens to be off, you're essentially killing two birds with one stone.

new to this. have a mature mother that is dying a miserable death. brown and dying leaves. big and bushy, about 7'. 7gal pot with organic mix soil. is it root bound? can i save it? lost another a couple of weeks ago the same way. just into flowering her when it happened. do i take it out of the room and take it back into veg? learning as i go with no training just light reading. HELP

It's not fucking nute burn. How old is this plant... it looks like it's either Mag or lack of N resulting in necrosis. But there are potentially a dozen other diagnosis that could cause those symptoms without more information it's hard to tell.

leaf blight i believe. its a disease

buy a fungicide like serenade and some hygrozyme.

search leaf spot of leaf blight on google and youll see. ive never had so im not sure the BEST way of getting ridding ofit. i heard unfortunately it hard to cure.
