rusty leafs? pictures!

[south east toker]

hello folks,anyone noticed this before? growroom temps have been high last few days in the uk you rekon it could be heat stress? s.e.t :confused:

It may be a zinc deficiency based on those leaves twisting in right angles, and zinc being immobile would explain why the older growth is undaunted. sometimes high ph can impede zinc uptake. see what the concenses is.

[Zandor]

to get the correct answer you really should give a few details of your setup.
Lights, temperature, soil make up, Ph. nutrients ect.

[snow owl]

correction, zinc is mobile

i want to think heat and too much plant food, even though i don't know your grow details, but that's what happened to my plants when i overfed them...notice how the top layers of leaves are brighter than the others, even yellow some...the red is probably heat, how close are your lights and what kind/wattage are they?...i always saw yellowing (on newer growth esp.) when i fed my plants with nutrients and not just water, but zandor's right, some details would help much better...zandor will probably help better with some details than i would lol

[Joel]

Im going to maybe upload some pictures of my main motherplant before I start the 12/12 cycle. Once it starts to bud there will definetly be pictures of the bud/plants. Other than that, those are looking really nice you should show some of the finished product when you're done :D

i would try SUPER THRIVE this may sort your problem short time but investigate the problem more this is a very powerful extreme concentration so becareful not to over dose BE CAREFUL.

Ok..first couple shots are scorching..basically if you can stand the heat on the back of your hand..that's a good distance for your plants..
The yellowing and dying leaves is something else..I am guessing it's a lack of potassium...
Since you are flowering it's possible a couple of your strains are eating up your flowering nute supply faster than you are adding it..
What medium is that? Is it pro-mix? or is it something else?
What is the PH of your run-off water?
And who makes your ferts and what are you giving em?
Here's a link to a great chart...

i dont think its a deficency as much as a lock up or the tips would not be burming. i agree the first pic is the light distance.

:p :pimp: :smokin: :rasta: :thumbsup:

[karmaxul]

to many ferts can cause ph that is low if you dont use salts to adjust. to many salts with over fertilizing will cause unbalanced or high ph making certain ions unavailable. ph of soil is tuff to judge with out a lab. i know a lab that will test your soil if you would like for a complete breakdown. drop an email to [email protected] if you are interested and i will contact the lab to get details for you or give you there contact.
