A deficiency for sure, but a tough one to pin down. All the ones that have yellow veins are the micro elements.

I would do this. First, get some Micro-Blast (Earth Juice), or similar micro nutrients. This can be applied foliarly for fast absorbscion (?). Also, on a couple of plants, I would dissolve 1tsp/gallon of epsom salts and apply that.

The reason I say that is, one of the possible deficiency's will be corrected by epsom salts. If so, good. If not, it won't hurt anything and eliminate a cause.

No bugs anywhere you can be sure of that!! I'm using humboldts full organic line. I don't know how to use/apply Epsoms salt to plants ?? I can't foliar feed at this point the buds are to developed
 
Dissolve 1tsp of epsom salts in a gallon of water, then water the plant with it. Yes, it's the same epsom salts sold at the drugstore or supermarket. When it's sold as a supplement, it's labeled Magnesium Sulfate and cost more.

I'm using the Earth Juice line and need to add the trace/micro elements (Micro-Blast), every few weeks or so. I'll bet that the humbolts line is the same way and needs some trace/micro supplement. Do they have something like that in their line up?

I use Mayan microzyme and the myco madness but like I said I use the whole line so I'm not sure ... *Anyways would it be ok to dissolve the salt in my water next feeding to the soil? *Cuz i feed em water every other time between nutrient feeding . *So it's water nutes water nutes etcc . *I just don't wanna mess the plants up by feeding the soil salt. *So please let me know thanks!
 
It's not salt. LOL IDK how it got that name, but look on the package and it will say magnesium sulfate as the ingredient.

I use Myco's also, but that is not the same as trace elements.

Do you think you could snag a bottle of MicroBlast? It's cheap and you just add some to your regular nutes ~1tsp/gallon or so up to 1tbl/gallon. Most organics seem to lack some of the trace elements/micros/minerals.

tell us what you mean by complete line up (what are you giving for base nutrients?). List them so I can help you cus I have some of their products as well. I doubt anyone uses the entire line-up cus that's like 10-20 products.
Also what is your medium?

I'm especially confused because when wetdog asked you what micro nutes you were supplying you said Mayan Microzyme and myco madness which are non-plant food supplements... so do you even know what you're giving your plants?

This is their cal-mag: http://www.hydroponics.net/i/134767

I wonder why people put all this shit in their plants if they don't know the purpose of each product.


I'm thinking it's Magnesium or Iron deficiency. A lot of one part nutes seem to lack magnesium.
It is iron deficiency if only the new growth is affected.
Yea, try epsom salts.
 
im using the full line for organic feeding chart.. let me list them for you


grow
bloom
deuce deuce
hum bolt
flavorful
mayan microzyme
prozyme
myco madness
myco maxium(didnt mix in with soil this grow cuz i ran out so i added peace of mind fruit and flower from fox farm instead)
humboldt roots
humboldt honey es

im using all these per their chart.. im on week 4 flowering..

i will go try the epsom salts as i have to water them tomorrow or next day with just water and will put what u said in per gallon and hopefully that helps something.

i know my last grow when i used the fox farm feeding chart i used their 3 part with 3 solubles or whatever and then i used sea mag in every feeding with nutrients (not with water only of course) and less of my plants experienced the yellow dots.. only my chocolope strain got the yellow dots with the seamag last grow now im using humboldt nutrients and over 95 perecent are experiencing this /burn/deficiency I GREATLY appreciate all ur help please help me get this fixed!
 
I was thinking Iron also, but it's not the new growth. It could also be zinc, but that's iffy also.

You really need a good micro mix and I don't see it with the things you listed unless I'm missing something.

That is why I suggested the MicroBlast. It's liquid and fast acting and solely for correcting micronutrient deficiencies, which is what you have. You can apply it as a foliar spray OR as a soil drench, added to your nutes.

You can avoid this in the future by adding things such as Azomite, Kelp Meal, Greensand, rock dust and the like. But they must be added to the soil mix before use and won't be much help right now.

There may be other liquid micro mixes, IDK, I'm using the EJ because I'm running all organic.

What (if anything) are you adjusting your pH with? I'm hearing rumors that GH's pH down (phosforic acid) may kill the micro heard of an organic grow - i'm currently trying to get to the bottom of this question, myself.
 
people that use baking soda to ph defianlty do kill the microbial. and ya shoulod be using a fully natural adjuster like a humate acid or folvic....and organic on. uses less also
 
i really want to solve this issue quickly. its time to water the plant with water only.. is it ok to dissolve the epsom salt in the water only mix and feed to plants or should it be done with my nutrients? thanks. reallllly appreciate all the help..

Water only with the epsom salts is fine.

Doesn't need to be combined with nutes.

i bought the EARTH JUICE ph up and down today and i got some epsoms salts i guess the next two water only feedings ill give them some epsom salt per your instruction. thanks again will keep u updated!
 
I think your right about the micro nutrients missing but I think it is lock out caused by Ph being to high in the soil. You need to check you soil Ph. If it is lock out adding epsom will not work.

Good luck

Peace

i did the epsom 1 tsp per gallon.. so i dont know.. it didnt fix nothing however i havent got the EJ i can try to pick that up but not positive.. last time i went i didnt see it .. my ph was like 6.2-6.4 runoff after feeding it nutes and one plant was as low as 5.8... i feed them 6.4- 6.5 ph everytime

someone please help me out!!
 
hey imma try to buy that EJ microblast stuff for my next crops.. however it still makes no sense why this is occurring.. as i metnioned the lemon strain going right now has no affect at all as the other plants do.. and there is 2 lemon plants all area COMPLETELY green no dots on leaves or nothing.. what is the soil ph supposed to be as i mentioned before it 5.8-6.2 ph
 
6.5 to 6.8 is best for soil. you are to low and locking out calcium and magnesium.
Doesn't look like iron, you can also get lockout by having salt build up or over watering.
Hopefully you are going by the less is more rule of thumb. remember plant only suck up 1% of nutrients and 99% water.
Soil naturally buffers itself as it dries out.. but over time you wash out all the lime or whatever is buffering the soil.
I think your P.H. is the reason it is low, because your leaves look healthy. epsom salt should fix it but i use cal-mag plus, has tons of stuff beside trace minerals and micro's.
what are your environment numbers? R.H. and temps?
