Deficiency from salt build up?

Hey everyone, I had and issue where a plant wasn’t draining properly and had a salt build up issue. WhenI realized what had happened I started to flush every day and got it down to what I wanted the ec to be. The ph was fine as well. I use promix and House and Garden Nutes. So once I stared to flush something happened to the leaves. The leaves that were affected we’re about middle to top of the plant. Im sure this is an issue whit the salt building up but what deficiency or problem could this be. The spots looked dark and then turned to necrosis. Mind you this happen in a matter of 3 days. Any help or advice is greatly appreciated.

That's a sign of over watering..

Too much flushing if I had to guess... or just from the nute lockout... Just return to normal watering...

looks like ph fluctuation to me

Doesn't matter what it WAS, you've flushed the piss out of it. Look into adding Yucca to your watering. Aids in removing excess salts every watering.

That happens when you flush PH is gonna drift mite go up may go down..

It's 1 leaf. I don't know how you can expect a solid diagnosis from 1 leaf and not the whole plant.

that looks like ph damage to me, as well....middle to top means its not mag deficiency.
salt build up doesn't cause lock outs, it just slowly cooks your roots. the plant absorbs the cations of nutrients from the salts they're bonded to, then the salts have to be washed out, so just water to run off at least every third time you water and you won't have this problem again

you flushed it a bit too much. its too wet. let her dry and feed her with a good dose of N. when you do water add some molassas and or yukka to help the soil. id be willing to bet she is just hungry.

Huh, interesting - I have always heard that salt buildup will cause all kinds of absorption problems. Don't the salt molecules block the nutrients from being absorbed? Also, yes salt does have a way of killing any plant it comes into contact with lol... That's why I switched away from Fox Farm (not counting big bloom tea)

What makes you think there is a salt buildup in the first place ?
The "salt molecules" are plant food. When there is way too much in there it can mess up the ph and the biology of the soil.
Fox farm is great food as long as you know its chems (salts).
IF you have an absorption problem , then "flush" with molasses and or yukka to get the microbes active again. but my guess is in my first post.

Good point, I used to never flush out my salts when I first started, and wouldn't notice a problem until week 5...

This whole "flushing is bogus' debate really confused me, because I thought people were talking about flushing during the grow, and not specifcically to get rid of overly salty and strong nutes... (which is true you should do this if you use fox farm etc...)

Thanks everyone, I think it might be a over watering issue. If the roots were already being fucked with by the high ec and then the constant watering. I actually noticed another strain of overwatering but didn't get those necrotic spots.

they may rebond with some of the cations, but that's not the real problem with excess salt

Learned a lot from this thread though. Thank you guys!

I dont flush out salts at all , i let the plant eat them. I'm not saying flushing is bogus but the term flushing is WAY overused on this forum.
When a plant is in lockout mode then it cant uptake food OR WATER. So "usually" flushing makes that worse. the object is to get the soil to dry out so it can start eating again. If you flush then thats another week of being soaked an not eating....
When i have a lockout problem , i feed with chemicals/salts to help the plant start to drink up some of the excess water, once she starts eating and helping to dry up the soil , then i can feed with water and soil food (molasses) and the plant will start to eat all the buildup.
Any plant soluble food is a salt.
fox farm just happens to be the chemical i use.

The stripey pattern on the leaf is from the pH being way off. Thats the only time I have had that happen. Your soil pH should be checked. I also grow in a peat based mix and the pH can get way off over time.

no, its impossible to tell from that pic. its necrosis. its eating itself. we can only guess by what he has told us not that single leaf pic.
You cant check soil ph at all. runoff dont count. Only a lab can test your soil ph.

I have two meters that test soil pH. One Hanna and one Apera.

i know but they are not accurate. they will only "help" to tell you if its WAY low or WAY HIGH.
