HOW ON EARTH DO I FIX ZINC DEF!!

[DIGITALHIPPY]

as stated how do i fix zinc def!!
i was thinking it was a magnesium def for the longest time. but this isnt that. plus the mag foliars and extra sensi-cal ive been giving has only helped a little.

FFOF, 2ed week+ flower 70-80 day and night, RO water + sensical / other additives

im sure you made sure your ph was w/in the borders right?

ive never seen a zinc def before.. but stitches guide says feed with something with potassium in it.
let us know how it works out.

i agree, must be a ph issue, in this instance i think u gotta check the ph again twice and be sure ur meter is calibrated, zync def. don't appear often since zn is present in the nutes and is needed in small quantities.

after getting ur ph straight, try foilar feeding with zn to cure them quicker

more info would be great, ph, ppm, which system, which medium etc.

p.s. a flush would be nice if those are in soil, else some fresh diluted(plain nutes and water at lower ppm then it is now) solution exchaned for some of the old one. Saying that because ur fan leaves have burned tips too which must mean they can not accept any more ions from ur ferts

p.s.#2
if you'r adding cal-mag u'r also raising pH, high pH(or very low) often results in zync/iron like def.

IM not too sure its zink....

Ive seen zink before and it resulted in a plant with stunted internodes.... meaning there was no distance from one node to the next.... this shows as whats called rosetting ..... where the nodes build up with no distance between them.....

you do have clear signs of mg def.... in some of the under growth.....

I thought it might be iron but with the clear signs of Mg def Im not sure I would bet on that....

the leaves dont look right for iron either.....


I might consider transplanting making sure you have lots of dolomitic lime.....
checking your ph.....

you might try to foliar feed with seaweed extract.....

thanks all for your replies.about 2-3 weeks ago i thought i had overfed my plants and gave them "extra" ro water ... after i had feed them, and then got a gnarly MAG def. (the older growth.) and it started to go away, but this yellow looks different then the mag problems i was dealing with.
plus i was foliar with mag + upped my cal-mag useage and added big-bud (/7% mag) and they have been in this yellow state for about a week, it seams growith is UNAFFECTED (still growing like weeds)
PH has been 5.8-6.2 range
i also added budblood (0-37-24) [alot of P] for a few feedings it seamed to help a little but not a whole lot.

ive got seaweed ex ill try another good foliar with that its been a week or two.







scegy- thanks for trying to help.
as above im running in FFOF (fox farms ocean forest) RO water usualy PH's at about 5.5-5.8 but when i add nutes (some buffer more then others) it goes up to 5.8-6.2 PPMS run 800-1250 right now and i tend to feed them every 2-3 days usualy every-other-day
-i usualy use the leaf tips as a feeding guide the tips have just a very small bit of brown. thats when i start to ease up on the PPMs'
but the top branches have pristine tips.


im stumped!
thanks!

Iron def...


NOw that I understand about the Mg def.....

YOur problem looks quite a bit like iron def....

Mostly that fits.....

Iron should be at the growing tips...

Iron is not mobile...

so if its iron the tips will be greener then as it runs out.....

the leaf interiors will be yellower.....

The most important leaves will be the first ones to show not the later ones...above that.....




Find some leaves that are transitioning and tell me if you think the tips are greener than the interiors....

or the opposite.... the tips are yellower and the interiors darker green.....


That should help with whether its a mobile issue or an immobile......

any idea on your ph????

Alaska brand makes a chelated Iron and zinc booster.

 

[DIGITALHIPPY]

#1 (red boarder) was what the top leafs look like now. they used to look like #1 (teal boarder) they come out super-yellow and change back yo green, partialy. its the whole leafs. the viens are just a tad more green then the leaf surface...
where did u get that alaska iron zinc??

 

[Verite]

Um, at the grow store. Alaska stuff is pretty popular at most of them.

i went to 3 hydro stores and one farm store yesterday to try and find that stuff...
no findo...

i did however check my ph and found it a tad acidic, so this feeding i increased the ph to the mid 6's (spot on from what i read) zinc and mag availablility should increase.

i guess i have to froogle my way to a bottle of 'alaska'

Heres a couple of sites with an almost identical layout. Ones in canada [BC] and the other in Kentucky.

yeah i have never ever seen that alaska brand at anywhere, but that zinc, iron supp looks pimp..

the plants will clear up, there looking nice perky and dank bro....could the light be too close, hot that its bleaching the tops? ive had that on the top part, but not quite as far out, and it was because i had the light way to close, even though temps were in check the intensity was bleaching them...

your kush pics at the end of flower i saw looked dank man, so you know you will have no prob makin these come through.

That looks like Iron deficiency. Look for Chelated Palm Tree Micro Nutrient Spray.....it has iron, mag., mang., zinc....it is sold at most home improvement and hardware stores and made by many different manufacturers. MaxiCrop also makes a kelp spray with added Iron if your into organics.

Edit: not everywhere has Palm Trees....DUH. Still, if you can't find this exact product, you'll be able to find something similar.

Spray-N-Grow: A micronitrient complex. (.1% iron, .05% zinc) Good, good stuff!! Oh yeah, is your ph straight?

 

[bodhiseeds]

did you ever figure out what was happening DH, did things get better? what did you use? i have had this happen before when i switched to well water, it boggled my mind, i thought it was a ph issue or to much cal mag. its definetly an iron or zinc def caused by something. hope it all worked out for you.
many blessings on your grows

[Skipload]

Because its new growth thats effected its most likely an immoble element, Iron is also my guess. Iron competes with phosphorus during root uptake. Are your phosphorus levels insane?

 

[Core]

heya Bodhi....i'm not an expert...but these marks also show up with a ph issue...or when you transplant your plants into a hotter or inbalanced medium...but to pinpoint you prob
you have to check the ph oh the medium and then work if from there...

 

[stinkyattic]

Iron lockout.
Spray-n-grow, GH Micro, or Shultz Iron Green (GO EASY; it's lawn food!!!!!!) mixed weak as a foliar spray.
Of these my first choice would be the spray-n-grow.
Metals lockouts show up real quick when your pH spikes up. At least they are relatively easy to fix! Didn't notice any discussion of this, but if you are running in HT or RW make sure you pre-soak them down to 6 before use, as they BOTH come in at a high pH from the factory.

 

[bodhiseeds]

thanks for the help guys....

got it figured out with a big flush, enzymes, and foliar.....

it was too weird, i think it was from manganese rich well water, manganese in high levels can lock out iron, but it also could have been massive dosing of mayan mycozyme hum tea, i was reading the back of the bottle wrong, or both my ph pens going haywire, or over cal mag. its sounds silly but thats the only thing different this time around.
it was like the ganja twilight zone having my plants beautiful with all the new growth shriveling up.

thanks again
