Plants leaves(Turning white)

Iv'e been trying to figure this out for a while, but still no luck.
I don't think it's an iron defiecency problem.
It started 2 weeks ago, it started on the bottom leaves, one leaf at a time it slowly became white, then the other and then slowly died(leaves).
The plant is healthy, but now it is starting on it's 2nd to bottom set of leaves. Iv'e looked at the leaves with a magnifying glass, and i don't see bugs. It isn't white spots, it just slowly becomes white'r, and white'r.
I will try to post some pics up tomorrow(getting new light :D), it bums me out though that the plant is getting sick when it looks healthy.
Pics soon tried with camera phone, but didn't want to give you guys a headache from squinting(Bad quality). I will try and find my camera tomorrow.

Are the tips also white? If I would have to guess without pictures, I would say it's a Mg or Zn deficiency. Maybe even a combination of both. Get some pictures and fill the new sticky troubleshooting form out and someone will be able to answer.

Oh and the reason I think it could be either of those is because Mg deficiencies tend to yellow and white starting at the bottom and eventually dying and working its' way up. Zinc deficiencies usually have white areas forming on the tips and between veins. Soil is probably really alkaline. Need to check that Ph. If so, you can bury some galvanized nails in the soil. They have Zn and help aid to give that micronutrient to the soil and plants.


P.S. Your welcome! (for getting back to you so quickly! :D )

Thanks man, i was going to take pictures but when i started to load it on my phone i was like dear god no, lol.:stoned: It hurt my eyes just looking at it, The whiteness seems to start from the middle of the leaf then work it's way, and then slowly to the other leafs on the branch.
And great response time:thumbsup:

You know, it could also possibly be a Iron deficiency. :wtf: my guess is one of the 3....once the pictures come it will be easier to tell then.

Do yourself a favor and get on that PH. Mg and Zn become unavailable in different PH ranges. Mg is good from 8 down to 6 but below that availability rapidly drops. Zn is good from 5 up to about 7.2 then it's availability falls off. Unless it's some kind of rootbound lockout, it's likely 1 or the other I'm guessing.

Really shouldn't be Mg since you have been feeding it. Could be Zn, Zn works hand in hand with Mg within the plant producing enzymes and stuff. Could manifest itself as both maybe if only one was missing?

How long has the same plant been in the same pot? Have you ever flushed?

I just moved it into the pot it is currently in, about 5-6 days ago since it's now technically thursday.
Im going to give the galvanized nails a try i think i have some, and yes iv'e flushed it before but not in this pot.
I will try to get an electronic ph tester this weekend or sooner.

I found my digi camera, and i will take pics as soon as lights out.

My guessis that your pH is out of wack!

Also, if it isn't your pH, too much phosphorus can block the absorption of iron

I would advise that you give it a good flush and then see if it rebounds.

The reason i think it has something to do with Fe is because the leaves are turning white. Fe is critical for chlorophyll production, without it, chlorophyll is not produced.


Best wishes,

Yeah, well i use filtered water because who knows the tap could be worse :P.
I have a water treatment solution nutes, It seems that it might have slowed or stopped, but i will take pics when lights out tonight.

Thanks

Not necessarily true....Tap water (if PH is correct) is actually pretty good for your plants. They have essential micronutrients in it that aids for cannabis. You should let your water sit for 24-48 hours (open top) to rid of the chlorine in it, but that's about it. If your Ph is correct with the tap water, then you should be fine with everything else.
