I must interject here and just say to MEDI ~ Quit polluting this thread! It's not yours to Hijack.

So you must load trucks at the fert factory. You should go talk to your boss about fertilizer reactance and altitude. Since you work at a fert factory, take a handfull of 34-0-0, put a few droplets of water on it and tape it up in your hand and keep it there four twenty four hours. You'll know the meaning of nute burn.

now you go on about altitude...you ok...???? you always go off subject dood every single time....
heres a lesson for all....
Suberin is highly hydrophobic and its main function is to prevent water from penetrating the tissue. In roots suberin is deposited in the radial and transverse cell walls of the endodermal cells. This structure is known as the Casparian strip or Casparian band. Its function is to prevent water and nutrients taken up by the root from entering the stele via the apoplast. Instead, water must traverse the endodermis through the symplast. This allows the plant to select the solutes that pass further into the plant. It thus forms an important barrier to harmful solutes. Mangroves use suberin to minimize salt intake from their littoral habitat, for example.
Suberin is found in the phellem layer of the periderm (or cork). This is outermost layer of the bark. The cells in this layer are dead and abundant in suberin, preventing water loss from the tissues below.
Suberin can also be found in various other plant structures. For example, the net structure in the rind of a netted melon is suberin.

heres some more for ya
Suberin Plays Vital Role in Plant Nutrient Absorption
Suberin is a waxy substance found between some plant cells. It primarily prevents water from penetrating tissues. But there's more to suberin than meets the eye. Scientists from Purdue University, by studying a mutant Arabidopsis plant that produces twice as much suberin as normal varieties, believe that manipulating the substance may lead to plants that better absorb nutrients. Their work appears in the current issue of PLoS Genetics.
David Salt and colleagues discovered which pathways particular nutrients use to get into plant shoots based on suberin concentration. By adjusting the amount of suberin in roots, plants could be engineered to allow for easier absorption of beneficial nutrients. Plants with more suberin were found to contain less calcium, manganese and zinc, and high sodium, sulfur and selenium in their leaves. "Just like animals, plants want to select the things they take in," Salt said. "They want a certain amount of potassium or a certain amount of nitrogen." The amount of suberin they produce allows them to choose how much they get.
Salt and colleagues also observed that plants with twice the amount of the waxy substance activated a defense mechanism to keep from wilting. Since suberin was restricting water absorption, the plant allowed less transpiration, or evaporation of water from the leaves. Manipulation of suberin might also lead to the development of plants that use water more efficiently.
The scientific paper is available at http://dx.doi.org/10.1371/journal.pgen.1000492 For more information, visit http://news.uns.purdue.edu/x/2009a/090522SaltSuberin.html

See how the leafs look dried out. Humidity and possible heat issue.

I've moved past what this specific problem is and focused on the nute burn topic (sorry for the minor hijack) so I asked a few resident experts if they could chime in on this topic. After researching this and the rooting structure and filiments and everythign I've come to an impass of good/bad/usefull and un-usefull advice with no clear answer.
I have a background in dendrology and plant systematics and my personal opinion based on experience is nutrient burn is very real and possible but I can't find scientific fact to back it up so if anyone (aside from medi) has something to add it would be very much appreciated.
I can't assist others with half assed info so I need to learn this.

Good Luck Kalebaiden
potroast
Uses the Rollitup profile
It's pretty easy to observe a plant react to something added to the medium, and easier still to blame it on the additive. Ocean Forest has all kinds of stuff in it and that should last the plant for the first month at the least. If the OP added nutes, and got this reaction, then it's probably the nutes. Who cares if you call it overferting, and another guy calls it burning? It's still a reaction to the nutrients, probably from having too much. Just use plain water for several waterings, and the plant should put out healthy new growth.

ya thjose where a copy n paste as you dpont seem to believe my info. seem to only think your the one rigtht at everything....anyways....
hps has nothing to do with it either, its all i use here, not sure how someone can see a dry leaf, its something we feel. unless some can feel with eyes and a blury pic..
pot roast in on track here. all iw as trying to show is its not the ACTUAL food doing the burning,.. yes we can over feed but its not food doing the burns..its cause the over feeding caused the ph to drop and made her not be able to get at the foods. someone prove it worng. take an unfed plant and keep using water and no foods and tell me you dont get burns eventualy from it starvin.
like i said ive done this suberin theory a few times. took a new seed and ran at 3000ppm for 1 month. not a burn on it. and i did same strain seed in same environment and care but no food..it burnt
some cal it salting up..but yet the food is a salt right from the bottle. you could use 200 ppm on a full grown plant and noit water it right by not letting it dry inbetween.,..what happens...we burn it. why..ph dropped from not letting iot dry. wasnt food as we only fed at 200 ppm....call it cup half full or half empty.

Looks like you've been giving it tap water. Tap water has lots of shit in it. Even if the PH is right it can still fuck up your dope plants. I learned the hard way.
Use distilled. Sure tap is cheaper, but even if you spend 25 bucks a month on water, that's still only 75 to 100 dollars for the whole grow and a hell of a lot cheaper than buying dope on the street.

I don't know about chlorine ever being a problem. I'm hydro and use fresh straight tap with no problems in grow or bloom.

Going on what medi says as a base, two things can affect your pH. The water your using and the nutrients you use. Go to mal-wart and buy an aquarium pH testing kit for 10 bucks and to eliminate all chance of your water being the cause use distilled water. Your nutrients will change your water pH and if your really concerned about the chance of a burn happening due to pH you might want to invest in some pH up and pH down (or use some limestone if the pH is too acidic or lemon juice in your water if it's too base <--crazy science theory)
but before fuckin with the pH you need to find out what it is.
