DYING PLANT PLEASE HELP

[illpacf96]

I am in the 14th day of flowering of 1 sage n sour and 1 master kush plant
I have been expeirenceing problems with the sage for sometime now
almost all of the leaves are curling in on them selfs, which i know is a over feeding problem
at the same time its showing deficiancy symptoms
the lower and mid leavs are turning yellow and falling off fairly quick with the stems turning a purplish hue, im guessing this is N
other leavs are showing sort of yellow stripes

the master kush had a magnesium deficiancy earlier and I put in epson salt to solve that which may have hurt the sage, though the sage had an mg deficiancy as well but it wassnt as bad as the master

im growing under a 250 watt
and as of yesterday fed 3 teasppons of flowering nutes per gallon in about 7 1/2 gallons of water
I put in 1 teaspoon of epson salt per gallon last week, not yesterday
I dump and refill resivour once a week
they get fed 3 times a day 5 min each, 15 min total
I flushed for 4 days straight last week, the new shoots look better
but with sighns of N and other deficiancys I dont know how long i can flush

these are some better pics of the bud

fill out the help form. It is somewhere around here
edit: it might be called troubleshooting form

Think your roots ran out of space there :(. Also ph issues, which could've been set off by the rootbound condition.

The troubleshooting form combined with those pictures would really give us the full picture though. :thumbsup:

ph is kept just below 6, and there on a 12/12, I put fresh drinking water in the rez, and there in rockwool cubes, this should cover everything in the trobleshoopting form that I didnt previously post

That's way too much epsom salt. I NEVER add it to my ferts or res, only foliar feed, at 1/4 teaspoon per gallon.
Drinking water? Like, bottled water? Do yo uknow the sodium content?
You say flowering nutes, but what kind? Tehy are all different and have different application rates.
Your plants are not deficient, they are severely locked out. Change your res right away to get any residual magnesium out of the RW and bucket. Go to tap water instead if you re using bottled drinking water, but check the tap water first for pH and EC. If you have 'soft' water, you'll need calmag. Look around here for info on that. Feed your bloom fert exactly as the manufacturer says, at pH 6.0, and keep it stable.

Thanks for correcting my mistake. I didnt even SEE they were using epsom salt last night in my half asleep stupor. Would've hated to send this guy down the wrong path.

Thx :thumbsup:

i dont know shit about growing and different strains but usually ph is to be as near 6.5 as possible (or anything from 6-7)
The WHAT? You need to re-register with a new username by the way, as this is a medical forum and AIDS is nothing to make light of. Unless of course you have a legit reason for that username, and it's not a joke.
And you're wrong about the pH. Go read before you try to tell people how to grow pot.
Hydro pH should be centered at 6.0.
Soilless pH should be centered at 6.4
Soil pH should be centered at 6.6.

pH 7.0 will kill or damage hydro plants.
pH 6.0 will kill or damage soil plants.

I already cleaned the rez when I added new nutes, and I use those 3 gallon purified water things for my rez, I would think that is better then Los Angeles tap water. so you think it is a nute burn problem only? Im feeding it the exact amount the bottle tells me.

actually I think you just filled in the missing piece of the puzzle right here.

When using distilled water, which is what you should be using and not purified water, you must add CalMag to your mixture. Distilled water contains no calcium or magnesium like tap water does. So you must supplement it.

Which is why you saw the magnesium deficiency before. You fed it with epsom salt which may or may not have relieved your magnesium issue but due to using too much epsom salt you may have created a lockout situation. Too much magnesium can lock out calcium uptake (which you have some in your soil even if you don't have any in your water).... which in turn due to lack of calcium it can inhibit your plants uptake of potassium... which in turn would lead to a potassium deficiency.. etc etc.. and it's just a never ending downward spiral from there.


Which is why I thought I saw multiple symptoms going on there.. hence leading to me cry "rootbound" prematurely.

If you are supplementing with calmag then I'm once again way out in left field; but I'm hoping this is what your problem is so you can get to getting those plants healthy again. :thumbsup:

to use tap water do I let it sit for a cuple days? what about all the flouride and other things they add to L.A. tap? and the water im using has no sodium in it.

[stinkyattic]

If you feel like spending the $$ on purified water and calmag, IMHO that is a better bet than tap water that you distrust. Letting tap water sit doesn't really change its chemical makeup significantly. But the burn symptoms were definitely an overdose of Magnesium and while you were sort of on the right track, it is as you can now see much safer to treat Mg def with a foliar spray, and keep your reservoir free of stuff that you don't absolutely NEED for plant growth, especially when you're on the uphill side of the learning curve! ;)

RO + CalMag Plus + a quality hydro fert + plenty of oxygenation to the root zone + good temperature and pH control and ample light = your basic plant needs.

[illpacf96]

so as of right now, should I just flush for a cuple days? and will this burn effect the bud?
