Deficiency or Lockout? Help needed...

[F.N.]

She is going to be a good size plant she will swell up some more tighten right up and smoke great.

She is going to be a good size plant she will swell up some more tighten right up and smoke great.

Thanks for your positivity and encouragement! I really hope you’re right! I figure they’re smaller in stature but if they can fill right out things will be just great!!! It’s been almost 5 years since I’ve smoked what I’ve grown. That’s actually how I found this place! Growing some Dutch Passion strains outdoor. I haven’t been active on here much. Only really started posting regularly a few months ago but I’ve been on and off here since 2012. I think I created this profile in 2013. These next few weeks can’t pass quick enough!

that is a micronute defc., likely Zn from the looks of it,.... question is if it's from lack-of, pH lockout, too much nute ion load in the pot, and/or caused by lights being too close (COB's can be deceiving in power!),....
... I don't see tip burn anywhere really, so I don't think this is a nute overload issue,... pH lockout seems unlikely since you're using RO water and minimal Ca-Mg, plus nutes are acidic (overload/toxicity will drive that down, not up BTW),... so I'm leaning toward lack-of and maybe lights proximity stressing the tops,.... using a hodge-podge of nutes is not wise,.. most are made to be used along with most all the rest of the line-up,.. this is calculated in the feed schedule, accounting for all nute elemts going in cumulatively,.. leave some base line up nutes out and you may fall short on other things, micronutes usually,... Most of those are immobile within the plant, so a low steady level supply is needed all the time,... Get the lights up to 20" or so from the top of tallest plant,... get a micronutrient supplement that has little to no NPK, (Earth Juice Microblast is perfect for this) and feed that up,... also, just to be sure, an in-pot pH reading would be wise too,... AN nutes "self-buffer" in solution only, not once in the pot,...too many other influencing factors!
Your pH meter, calibrated recently? Stored in storage solution? If not, it's accuracy will be suspect,.. if that electrode bulb gets dry, or stored in water, it'll ruin it soon,....

Thanks so much for taking the time to help me out. My local shop doesn’t stock the earth juice microblast product you mentioned, so after looking around online I noticed AN makes a product called Revive. Taking into consideration your advice against a “hodge-podge” of nutes I decided to pick up the AN Revive as all of the nutes I am using actually are AN with the exception of The calmag I’m using (CaliMagic from GH). I’ll be adding it to their feed today and hopefully I’ll see an improvement over the coming days. Thanks again @Waira I greatly appreciate your help and the help and input I’ve received from countless others on this site. Thanks to @F.N. @Mike20132 @bushmasterar15 @NateNobody @Arthur @namvet25 @STILLSMOKIN. With a bit of luck I might have a first taste of these buds before the end of May (an ok cure by then...) it would be even better if I end up with enough to actually last a 6 week cure! Lol!

A good pH meter is expensive. I think I paid about 60 pound for mine. @Waira or someone else might be able to recommend a good soil tester (I am DWC, my meter would only be able to measure what you're adding to the pot, and while that is important, knowing the pH level in the soil is a bit more important.

Testing run-off isn't the preferred method, but until you can get a meter you can try measuring that with something like this:

The color gradients between 5 and 7pH are dramatic enough to know when you've got it "about right."

Not perfect, but is better than nothing.

Looks like it ate my amazon link. Search for pH-Fix 0-14 and you'll see some options.

I think I’ve read in the past that @Waira recommends a product called accurate 8 if I remember correctly. In the meantime the most immediate thing I can do is give this revive product a shot and see how the plants respond to it. I’ll be mixing up a feed for them later tonight. Fingers crossed!

Thanks mate. This might be a good test for others as well to see if this product is worth its salt! I haven’t seen it mentioned on here but then again I didn’t do an actual search on here for it (which I’m totally about to do! Lol)

oops! Right you are on using the AN base line,... misread that! GH is fine for a stand alone Ca-Mg supp', I like it's 1-0-0 formula,... Revive is fine too, just $! As long as it has Zn and Fe at least,.. but FYI it is not complete for micro's, disappointingly,... (No B, Mo, Mn, Cu, Cl,....)
Are you in the States or EU? I don't know what's in EU for availability, but you local shop may have an equivalent, just ask them and be specific about broad micronute coverage,... The Accurate 8 (Control Wizard) may not be under that brand, in UK I think,...but other have found the same unit by simply looking at the design,.. same unit, different name, but same Chinese factory source!
There's one step up if you can get it, and the price isn't insane,... Optic Foliar makes excellent products, one called Transport; it's a carrier solution that allows temporary penetration through the leaf cuticle, so whatever is dissolved in it get carried right on in! Nutes, or micronute supp's especially are great used as a foliar spray; it's the fastest way in, and the Transport acts immediately, not over days/weeks like some stubborn micronute defc.'s do,.. Usually at this late bloom stage, foliar is unwise, at least standard methods using supp's and wetting agent (helps coat and stick better, critical!)... this puts a lot of moisture on the buds, a mold risk.... Transport needs no wetting agent, and no need to soak the hell out of it either,...

Thanks again for all the advice. I’ll look into those for future use. Yeah 1L of revive was $57 CDN with the tax in! Not cheap! They didn’t have anything smaller and I wasn’t there to ask questions for any product similar to the microblast you recommended. Had my wife pick it up as she works a min from the shop
