Sulphur Deficiency? Please help...

Hey guys my blue city diesel developed a deficiency about two weeks ago. I thought I corrected the apparent magnesium-potassium deficiency with some teas and epsom salts but I left town for the weekend to come back to my garden full of deficiency. Anyway I don't want to misidentify the deficiency again and was hoping some of you more experienced with deficiency could chime in.

I am growing in down to earth pro mix amended with:

Minerals: Oyster shell flour, azomite, greensand.
Bio-live, Blood meal, Fish bone meal, Seabird Guano, Bat Guano, Earth Worm Castings, kelp meal

Tea containing: Bio-Live, Kelp Meal, Kelp Extract, Guanos, EWC, and unsulphured molasses. (One time fish bone meal and blood meal added to tea).

Foliar fed with Humboldt Counties Own Verde and Kelp Extract.

Top Dressed and watered with Epsom salts.

Anyway here are some photos of whats going on in the garden.

Heh I'll play. Pretty sure there's a form to fill out somewhere, but what are u feeding them? I've grown blue city diesel for years, but never managed to get one looking like that...

Thanks for the reply Granger, I will be ordering Microblast today. But what exactly is the deficiency? Sulfur? I imagine a micro blend would correct it but I was hoping to address the specific nutrient.

Thank you!

I found the form, I will attempt to answer more questions from it with time. It is rather long and I don't know the answer to everything on it... This pheno of blue city diesel seems a little finicky but she smells great! What do you feed your blue city if you don't mind me asking?

Thats not a sulfur def.....

It has the earmarks of iron....

However....iron is almost always related with a ph thats too high....


You dont need the micros....atm.....

With all that organic crap you are using you should have plenty of micros...

check the ph of your runoff...


Let me explain what happens with an iron def....

Iron isnt translocatable like some other nutes....

When iron first runs dry....the tip of the leaves are green..... but the inner part turns very chlorotic.... yellow....


Again....most likely its high ph...not that you dont have enough...

Burnt, I agree about the pH. With the additives, there's no telling what's being released and what's being tied up. It will probably in time get sorted out, but for now the Microblast will probably IMO fix the plant until the soil can start feeding the plant. I think it's worth a try as a cheap solution. -granger

I simply said....at the moment....


test the ph first then go from there....

I didnt see anything that points to ph ...but thats what the plant looks like....


Im not inclined recommending full organic grows ....


using something like pureblend....which I consider semiorganic is a better choice IMO

I will test my runoff again. It was high in the past when I tested it so i have been correcting by feeding lower ph water than I would normally.

I have to laugh and smh......

You didnt think that your ph issues were worth mentioning????

Whats causing that high ph???

The high ph was caused by the down to earth soil... I didn't mention it because I thought it was a fluke. I have tested runoff at 6.4 PH when starting with water of a ph of 6.4... therefore I thought I had either corrected the issue or had a fluke test. Also I posted this fast, should have mentioned.

When I work sick plants ....I like to look at the pics.....

assess what I see.,...then read the narrative.....

If the narrative makes sense compared to the pics...... I feel ok about giving advice....

For an iron def....I would guess its going to take a good bit over 7 ....likely 7.5 to 8 to cause deficiency....

The pic looks like iron..... but the narrative isnt quite right...

I've been growing it for a few years now, and gone through a few different nutruest lines in that time. Gone back to florinova for this run. Its always proven to be a a great producer, and pretty resilient to whatever problems ive thrown at it. Unfortunately, ive decided to discontinue growing it, cuz it's played out in the pnw like blue dream is in california... that and I cant stand the taste and smell anymore...

I was planning to run my blue city in hydro using the flora series. I agree that Blue City Diesel is played up in the PNW but for me it has high medicinal value, a unique and productive high, and unmatched candy-like flavor. I will eat up any and all blue city diesel I can get my hands on.

I gotta agree that it looks like the beginning of an iron issue, but i dont think its because of your PH. PH in soil doesn't affect things usually. I think you're throwing too much at them. remember organic material needs to be broken down before its usable. and usually its best to let your batch of soil cook (sit mixed and moist) for a month or so at least. it lowers the 'hotness' of your mix. guanos can be very hot and hurt things when over applied, especially when you're soil mix is complete to begin with. also bone meals take time to break down, so adding it to a tea is pretty much useless. If i had to guess, i'd say you're running your P too high which is hindering the uptake of your iron. which is very hard to do in soil. problem being is you're throwing everything at it, and its near impossible to 'flush' out all that organic material you're adding in. its not like in hydro where you can dump the res and start over. plus its really hard to diagnose where the exact problem is because you're throwing everything at it at once.

for trace elements, all you need to add is azomite. nothing else. its the best you can get.

you're adding a ton of kelp products, molasses, and epsom salt.. so you're adding very high amounts of potassium, with magnesium and sulfur.. high levels of potassium. K, Ca, and Mg all work together on a balanced ratio. having extremely high levels of K is going to affect calcium, magnesium, and sulfur uptake.. it will also affect everything else.

regardless, soil is very forgiving.. may i ask why you feel you need to brew all that stuff in your tea when your soil mix should be complete enough to carry you through? and why are you spraying epsom salt when you dont have any sign of Mg issues going on?

try to remember that more is not better, and in soil things take time to break and and become available to the plant.

if anything, you should just brew your tea with a small handful of EWC to breed micros, and water with it once a week and let them do their job breaking down all that organic material into a usable form for the plant. stop your spraying, stop with all the extra crap. run the soil mix by itself and thats it.

see the 4 groups, one side pulls from the other side, and within each group, the ones on the left pull from the right.
more is not better, and everything must be balanced.

Is it possible to get a copy of that report? Is there a link to an online source? Those two pictures have me intrigued, and I'd really like to keep studying... Looks like a lot of good info there.

OP never came back with a ph test......

based on what his mix was I didnt think it was going to hit the 7.5 to 8 required for this to be a ph problem....
