MAGNESIUM Deficiency? BAD leaf curl *PICS*

strain- top 44
nutes-floranova 600ppm
ph- 5.7
temps 65-80F

As the leaves began to curl upwards and rust brown colors appeared on older leaves I began to think it was a magnesium deficiency.

My water is hard at 200ppm's so I figured MG was getting locked out.

I added 1 teaspoon/gal of epsom salts (magnesium sulfate) to try to correct the solution. Should I be doing aynthing else?

Did i miss it completely?

Epsom salts are having little effect after 4 days.

I've had this before, could be a mag def, but whats your PPM's and Ph? I figured it was a because of too strong of nutes in my case, it was over 1800ppms and i backed it down to 1100 and didn't let it go past 1400 and it seemed to come out of it. If you used the epsom salts and it didn't help give it some more time then you'll know if it was a mag problem.

good luck!

damn what nutes are you running. Im doing 600ppm floranova and never reach more than 1200 with its demands.

I am fairly sure the diagnosis is correct. Slik, note that my Mg is likely getting locked out due to excessive calcium. I dont think adding more calcium to my hard water would help. I think the epsom salts are the way to go.

Anyone think I should be using more nutes?

That's because you don't have a Mg deficiency and by adding something they didn't need, you may have made matters worse. A Mg deficiency shows up in the lower leaves first as a pale yellow leaf chlorosis. If severe enough it will work up to the middle.

pH adjustments and the forum cure-all of whatever ails ya, epsom salts, is not causing your problems. BTW, I'd be blessed to have a TDS of 200. How's 790 fer ya?

Rust colored spots are usually caused by too high a PPM of salts (nutes).

Floranova what? If it's the Grow formula it contains Mg but the NPK sux - 7-4-10 is NOT a good food to support foliage production. Again, GH has it bass ackwards on their NPK values. It should be a 10-4-7 unless for some reason water plays into the uptake potential.

That high amount of K will cause a N lockup as well as Ca and Mg. I don't know why these hydro manufacturers constantly do this (screw up the NPK values) but most do.

I use the GH 3 part, not the flora series, I've been pretty happy with it so far, I'm on my 3rd grow. I generally cut the amounts from the bottle in half then check the ppm's, I try and keep the max ppm's between 1400 & 1600, but it really depends on the strain, some can take higher strength nutes some can't you just have to watch and see how it responds.

ok so my nutrients are bogus, by following a trusted plant problem chart I made matters worse and 200ppm water is good to go....

this is all a lot to take in here.

may I ask what ph adjustment would help my plants then or would you prefer to just point out negative facts.

..don't give my plants water or nutes...

they are in aeroponic chambers and I believe they are begging currently....although ben may be about to bestow upon us a blessed ph# that will solve this.

thanks for the replies guys:clap:

ha, I didn't realize that. although, by some of your comments, I should have. sry, I don't know crap bout no aeroponics, lol. I'm a newb too! I prolly wouldn't have posted a comment if I'd known...lol

I think he just means he don't know bout no aeroponics either...idk, imo...:weed:

hope ya get that sorted...good luck.

Well, even though you seem to be taking your anger out on everyone that posts(its nobodys fault but your own that your plants are sick), I will offer up some advice.

First a question, if a nutrient is getting locked out, why would you add a bunch of it to your res? If Mg is getting locked out, pouring a heap more in your res isn't going to solve your problem, you have to resolve the lockout before your plant will be able to use it. Basically what you are doing is putting someone who is choking in a room full of oxygen they can't even use. Gotta get those metaphorical chicken wings out of their metaphorical throats before your plants can breath again, know what I mean?

Change the water in your res first, you have to get all of those salts out of there, they're whats probably causing the lockout, that buildup of salt(salts=chicken wing). I have always read that Mg is locked out at a low ph and by excess fertilizer salts. When you put new water in your res, up the ph a little bit, I'd say somewhere in the 5.8-6.0 range, and keep the ppm low(this is the fresh air). If all goes well, your plant should start to utilize the Mg already present in your nutrient solution(no chicken wing + clean fresh air = yay they can breathe), any additional Mg added will just create new problems.

With that said, I have never had good luck with epsom salts, they always just seem to make the problem worse.

are you kidding me? I asked for constructive answers is all from one asshole. thanks for being a dick.

the reason i posted this is because I was skeptical about what you are ranting about. The problem chart I have, suggested to add epsom salts to CORRECT THE DEFICIENCY. Wow I thought that is odd mebe I should post a thread about it.

All i get is one guy hating on me for following the chart and you hating on me for something.. wtf r u talkin bout with the chicken wings.

Since the 4 days of epsom salt nothingness I have already flushed and added a lighter load of flowering nutes. They are still curling, but not getting any worse.

They are still growing vigorously, which is why i must flower.
