Zinc Deficiency? Doesn't look like light burn or Nitrogen to me, the calmag was prob a good idea, but if your PH is what you say I doubt it's a lockout. Hard to tell but is there bluing or is that lighting?

Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.

The GH Micro label says there is 0.015% Zinc. I guess that means if I mixed it at half strength, adding 16ml to 4gallons (15L) would be 0.16ppm. *edit posted with bad math a second ago, fixed*
Is that low?
I haven't checked pH or EC for a couple days until just now. EC dropped to 1.3, and the ph rose to 6.2, not ideal but ok. Guess these plants are starting to really take in the nutes. Only been around 4 days since res change. I might go do one tonight since the levels dropped so much already.
I don't think there's any bluing. Nothing appears blue in person up close. The little flecks of blue and red you see in the photos are caused by specular reflections of the blue LEDs, so they move when you move your viewpoint.
Swear the leaves look a tad more crinkly today. I think that's usually them asking for calcium, right?
At least the roots are looking awesome:

Since GH Micro uses Calcium Nitrate, does that mean the 5% calcium and nitrate is fulfilled by the same compounds?
Calmag is 2-0-0, has 3% calcium and has 1.5% Mg. GH Micro has more N and Ca, and Bloom has exactly the same Mg.
The HowardResh stats previously posted say these plants can use 340ppm of Potassium. To get anywhere close with my current nutes, I'd be at roughly 126ppm Mg and 422ppm P (10x the suggested concentration there). Obviously I won't do that.... but I'm curious if there is as much danger in over feeding those elements as Nitrogen? Do they also cause leaf curl and burned tips if overdone?

That 1.5 and 6 you had was spot on, even 1.3 and 6.2 are fine, 1.3 being on the low side. I would hold what you got and see if they recover.
Don't want to give bad advice, but I think with those numbers they will steady recover. That little bit of tip burn is a good first sign to look for next time, but it happens. I thought I saw blue stems, but looks like the 2.2 was the problem, they look good otherwise.

Thanks for that! Very useful.
Lucas actually recommends twice the bloom vs micro, but those ratios you posted look much better.
Just to clarify... If the first % num is the error margin.... Then what is the small +\- num at the end? Thought that one was the error margin at first.
Trying to figure out what compound my bottle of Fauna Marin Ultra Easy K is. The bottle instructions only say that 1 ml per gallon equals 90ppm of K. Well I did a test using a quart, and the ppm raised by 100 or so. The bottle says the only other ingredient is mg at much lower levels.... But doesn't tell my the compound. It's moslt likely a simple chloride right? Definitely isn't kno3 as nitrates are a no no is reef tanks.

arolvl, do you mean that the lucas is very similar to the Maxi bloom? Only reason I didnt want to use a 1part was I heard some of the elements could PPT and you might not get as good of results as separating into at least 2 parts.
Also quick note for queequeg152: if you look at GH micro's label on the website, it doesn't list any of the micro nutes for some reason. But I have the bottle in front of me right now, and it definitely has most of them in nice quantities.
Boron 0.01%
Cobalt 0.0005%
Copper 0.01%
Iron(chelated) 0.1%
Mn 0.05%
Molyb 0.0008%
Zinc 0.015%
(side note: my home PCs have a porn blocker which also blocks all cannabis sites... Im finding out right now how impossible it is to find info on GH nutes outside that community! I end up looking it up at work lol)

sorry lol, im just waking up i was up untill 5am.
it goes like this.
N (NO3-),240.043(mg/l value),26.3%(gross error),+/- 3.6%(instruement error)
in hydrobuddy you set the instrument error to suite your scale/volume measureing equipment. i have a cheapo scale from harbor frieght so mine is .01 gram accuracy.
yea i mentioned grow on accident, i meant bloom.
this is where i got the density information, this is another less useful nutrient profile calculator that our friends in the cannabis business gave us. its at the bottom of the little java app thing.
http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm
check your volume, .5ml is waaaay to little nutrient. when i used the three bottles... beffore i wised up
i was using 18 micro 18 bloom 8 grow (per gallon)i was targeting the lynett morgan profile back then.

I had ounces selected for "Mass Units" instead of grams. guess it must be using that for all the g/ml density stuff? but I get the same results as you when I use grams.
This shows me that my current mix has nowhere near enough Sulfur (-90%), and way too much Copper (700%!!!). Thanks for the info. Going to start looking around for possible better matches.

When I enter 14-10, it gives me this result:
NPKCaMgS: 132-81-144-132-55-36
Pretty close, but lower on K and S. Wonder why? I tried using the uncorrected K20 and P205 thinking maybe that's what you did, but that result was slightly different too. Odd.
I also noticed that queequeg152s results only happen for the uncorrected amounts. So if you enter the 5% for K, but select K20, it will auto correct that to 2.182%. I'm assuming the corrected % is more accurate.
With the auto corrected K20 and P205 values, it says this is the best match it can find:
Bloom: 21.25ml
Micro: 11.79ml
EC= 2mS
NPKCaMgS: 193-143-250-193-98-65

So it appears the BEST thing you can possibly add to Lucas to get it really close to the HowardResh #s would be Potassium Sulfate.

Nice find! Down in the suggestions below on the same page I also found some stuff that's supposedly "hydroponic":
5 Pounds Sulfate of Potash Water Soluble Fines . This will make 5 gallons of 6% Potash Solution.
Naturally produced multi-nutrient fertilizer rich in potassium and sulfur.
This grade of Potash is formulated for maximum water solubility.
Use in solutions and suspensions where a safe non-chloride and low salt fertilizer is desired

13 bucks for 5lbs, so it's a slightly worse deal... wonder if there's really anything to the chloride free and easy solubility claims...
