Is this nute burn or a deficiency?

[Cyber9]

Hey hey, I gave my plants a feeding of 7/ml floranova last feeding, and i noticed a sick leaf today.... all other plants seem to be ok... one had some yellow blades in new growth.. some look pretty dark on the tips which makes me thinks its burn..

are you worried about that single leaf? wow should see what falls from my ladies.

no issue yet. plants look great well fed id put that slight discoloured leaf down to a drop of sweat if only leaf or the first feed maby when res wasnt mixed through with ph/ec variation, no signs of overfert here although i wouldnt increase ec further just yet.

I push my plants pretty hard sometimes growing near clones to near harvest plants in my flower room on a single res, a bit of tip burn isnt the end of the world just this plants current limit. Take note keep ec/ph stable for a week and watch for more symptoms or improvement/ lack of tip or leaf burn in new growth.

Hahaha nah man I'm not sweating i know its just a leaf thats gonna fall off

I'm just trying to understand what is wrong so I can correct the problem in the future and become a bettter grower.

But yes thanks for the advice, this could very well be ph related, last watering I feed the first 1 with hot nutes, forgot to ph it... thought i corrected the problem by flushing it with ph'd water... guess not lol

this is the first sign of rust.. pull off that leaf or it will spread fast.. 2 thing you can do.. I like to give a sulfur treatment and spray for rust and meldow.. try to find bayer garden.. this can fuck up a harvest when in full flower.. and its a bitch to come back from.. hope that helps.. keep close eye on your babys man

Rust? I don't think its the rust fungus.. I just looked at pics of that, and it seems to attack the vains of the leaf rather then the leaf its self... I think its a mag-cal def.... Like its rather dry where i live, this rust fungus stuff strives in high humidity... *cross fingers*

I had this happen to a big crop.. just keep a eye on it.. it could be a sign.. I saw this on a few leaves and 4 weeks in I losted control with it.. that was a dry room when the weather was warm..

hold up i wouldnt rip thaT leaf off just yet. its quite easy and obvious when a leaf looks too far gone in this case you just dont want the problem worsening my money is on slight over feed or feedings,

what ec value are you at?.
wks veg or Age of plant?

looks higher up in the plant maby a decent size fan leaf its worth leaving in place for now specially if it is getting direct light. If i was you id take 0.2ec out of total salt value after adding nutes and additives, then lower PH (if need)to about 5.8 allowing for more drift in a recirculating hydro setup and is a good value to start at in most growing mediums like coco/ rock wool.

Post up the same leaf in two day mate.

It's not rust. Never seen rust on MJ.

I second that. You can get what they call 'rust' on MJ, but that is definately not what it looks like. pH/nutrient related.

Looks like the 1st stages of a calcium def.

Cyber9 the plant looks healthy as i wouldnt be worried about it, its not nute burn otherwise your leaf tips would be burnt and yellow...
