stickyrussian

shortage of iron mimicks quite a few nutrient deficiencies.

need pics really tawny m8

Click to view attachmentcant take a good pic of my plants coz of the lights so found one on the net the same hope this helps

what nutes you using and what's your pH?

spotted you are Ionic nutes from your profile, I had a deficiency early on in flower which looked like your picture but it was just the growing tips were very pale, I lowered the pH cos' I thought it was a nut lockout but also added some epsoms to the res, the plantd looked better within 2 days.

I ythink it was more Mg deficiency than nute lockout actually

well over a week ago the ph just started goin up so i ph down it to 5.8/6.0 next day it was up again (leafs started yellowin)so i do the same every day after about 4 days of this i cleaned res and refilled it the ph is ok now but the plants are yellowin about 6 inch from top down of 1 and about 4 inch of 2 .just bin lookin on net and the pic i put up is zinc defect looks the same as my plants but 1 of my plant looks worse than the pic shud i flush them and refull or is the some thing wot i can buy for them to make them better ..thanks

just bin to my grow shop and bort some general hydroponics floramicro and some vita link foliar spray can any tell me if this will help .the man at grow shop said its coz ive bin mixing nutrients in cold water

sounds like Mg. def.. (Magnesium)
Yellow new growth - Iron def.
Yellowing stripes/chevrons Mg.

could possibly something completly diff.
cant tell without your own picture.
If they were my plants i would treat with Mg.


"the man at grow shop said its coz ive bin mixing nutrients in cold water"
ERRRR WTF!

get yourself to a BIG boots branch and get some epsom salts, cheap as chips and enough for a few years.

put about 3/4 teaspoonfuls in a container and dissolve in hot water then add to res, that is what I do with a 200L reservoir, if yours is smaller adjust for size.

That is, if it IS Mg deficiency, as has been said pictures paint a thousand words.

if i take some leaves off and take pic will that help and ive just read that lime works just as well as epsom salts cud be wrong tho but got lime if right. i need much help as i can get thanks for the replys

why remove it from plant ????

If you need to of course..... then yes go ahead take off the worst affected leaf and show us....

It's an Iron def, not (Mg)

The picture shown is not his plant..... its a random one of the net.

its not a random pic its a iron def the same as my plants

THE PIC YOU HAVE PUT UP IS A ZINC DEF!



We cannot help you if you cant post a pic of your own plant mate....
could be any manner of things.
many deficiencys show similar effects to begin with..

I still think you have Mg def. Personally...
Zinc Def. is quite rare..
Go take a pic....... OF YOUR PLANT!
Peace out

heres a pic of when i had Iron def.




no green veins as such...

It's not Zinc, nor is it (Mg) - the plant in the pic is (Fe) deficient!

thanks every one it was mg def sprayed em with epsom salts lookin better all reddy nice one

That pic is a zinc def pic from Nietzsche's guide.

Looks like a classic Iron def to me - hey ho.
