Red stems and yellow tips

This plant has been through a ton. when it was only a month old it was chopped when the lights fell.
as it started to heal from the chop and act as if it was topped, it was stressed when my lights were on for 24 hours during the 12 12 period.
it was stunted after that and had about 2 stigmas to the entire plant. now it is thriving flowering well.
I am only trying to find out what is causing the red stems and the yellow tips. i have looked at the plant problem guides and i think it is either from nutrient burn or a sulfur deficiency.
thanks for the help

red stems and yellow tips unless you know it's over feeding may be a phosphorous deficiency or mg dfncy, this may be corrected by adding a tblspn of Epson salts per ltr of h2o

i am not sure that that will work...
im pretty sure that the proper ratios for epsom salt is 1/4 teaspoon to 1 gallon of water, so it would be 1 full teaspoon per 4 gallons or 1 tablespoon per 12 gallons of water.

I don't know why you guys offer advice when you clearly don't know what you're talking about.

It's not a magnesium deficiency. A mag. def. is easy to spot and none of the symptoms are there (e.g., V-shaped leafs, light green between the veins, lack of succulence), or at least I didn't see them in the pic.

How in the world would epsom salt (magnesium sulfate) cure a phosphorous deficiency? Notice that I put Magnesium Sulfate, as that's what epsom salt is. Notice that there isn't any phosphorous in it?

You're also wrong about how much to add. The most epsom salt that one would want to add would be 1Tbs/gal. I usually don't go over 2.5 teaspoons/gal, which is 12.5ml...1Tbs is 15ml...1Tsp is 5ml...



Now, to the original poster-It's possible that you could have a slight sulfur deficiency. If this is the case epsom salt would work for you...

What nutrients are you using and how much? Also, what do you keep your pH at? Do you use distilled/RO water or tap?

There are also some strains that naturally have a red color to their stems, strawberry cough is one that comes to mind...

right now im not too worried about it anymore,
nothing has spread to any other parts of the plant and the red in the stems is starting to dimminish naturally.
i am unsure of the types of nutes off the top of my head i am out of town right now and will let you know when im back into town.
I do know, that i have been giving them 2 tblsp per gallon of water, and 1/2 tsp of molasses per gallon.
i use tap water, i havent rater the ppm of it, but i tend to keep the ph any where from 5.5 to 6.3
my ph tends to fluxuate, i have not used any controll substances for my ph has never gone to low or to high.
I did read in Ed Rosenthals "closet cultivator" that the proper ratios of an epsom salt mix are 1/4 tsp epsom salt per 1 gallon water.

No way will that fix a deficiency... Go ahead and try it sometime and you'll find that ratio is way too low. Could he have been talking about using 1/4 tsp/gal as a regular feed schedule? I've read a few books, gone through it myself, and I can say without a doubt that 1/4 tsp/gal is too low to fix a deficiency.

i hear yah, ill have too look at it again.
i think he might have been talking for a foliar feed mix, but im uncertain.
i appreciate the help my man.
ill post some new pictures when i get back into town. before i left it was staring to nug up mad kinds.

I read to use a 1% concentration of epsom salt for foliar feeding. I did that and it seemed to be too much. If you're going to foliar feed with epsom salt (which is a quick fix), it would probably be best to use a 0.5% concentration, and make sure to use a penetrating agent. I use Penetrator by Dutch Master. If you don't you some form of penetrating (maybe it's called wetting agent) it will get caked on your leaves and it's a b!tch to get off.

cool man, i will definatley try these things as needed.
he goes into wetting agents a little bit in this book i just read, i understand the need for em.
thanks man, i appreciate the help.
with percentages though. how do you measure that in say 1 gallon of water?
like how much of a certain measurement will reach the .5% dose?

Yay!!! Strawberry Cough. Im growing 4 SC's with 2 months VEG in the oven already. Cant wait

I'm only a week away from harvest with mine. I like it a lot

It's a lot easier to do it in metric units. There are 1,000 mililiters in one liter of water, and each ml of water=1g.
So... 1/100th=1%=10g...
and then 0.5% is equal to half of that=5g.
I could have done the conversion straight to 0.5%, but I wanted to try and explain it to you.

*Disclaimer* I'm a chemist and this isn't truly a 0.5% solution of epsom salt. However, in the books I read they said to do it this way. To truly find what 0.5% is, you would have to use the molecular weight of Magnesium and Sulfur and go from there. It's not hard to do, but there's really no reason to go into it.

And I almost forgot. If you want to know how much to use per gallon, just times 5 by 3.8...as there are 3.8L in a gallon.

my man. i appreciate it tons.
ill post some pictures of my progress when i get my camera back.
i am also about to change the nutes cuz i just now learned about what nutes do what...
and i found that i have a 2.5-2-3 nutes. im gonna change it to a higher phosphouros and less nitrogen nutrient to hopefully promote more flower growth
