So how can you tell the difference between lock out and just plain deficiency?

Well,I gave it a shot- nute deficiencies are still mostly a mystery to me,but I'm
here for moral support...
I have been looking at pics though,and it looks more like not enough P than too much...
But if it's coming from me,it's just a guess...

I don't know!!!!! I'm new at this. Lol.
I just figure that they are so friggin dark that it has to be a lockout.

Hmm... I was thinking too much because that locks out Ca and Mg.Well,I gave it a shot- nute deficiencies are still mostly a mystery to me,but I'm

Hey y'all!
I'd like to welcome you to my journal sponsored by Barney's Farm Cannabis seeds!
I was contacted by Barney's awhile back and was asked to run some strains for them.
I was excited at the opportunity set before me and I can tell you that it was very, very difficult choosing between all of their incredible strains, in fact it took days and the beautiful bud pics on their site didn't help any. I ended up making a list and when I couldn't decide between them, I pulled out the 20 sided dice and let fate decide for me, otherwise they might still be waiting for my list. This is how I landed on Gorilla Zkittlez, G13 Haze, CBD Blue Shark and Peppermint Kush.
I also thought that I would bring the strains that I won from Gary at The Vault along for the ride.These will include Barney's Triple Cheese,Red Diesel and Peyote Critical. Blessed with all of these beautiful strains we sally forth into the excitement and uncertainty of seed germination!!!!
This will be a hempy grow using Greenleaf Nutrients ( GLN) Mega Crop's 2.0 one part formula and also their Sweet Candy. I do have GLN's Cal-mag Plus as well as their Bud Explosion flower booster. I'm not sure if I will be running the Cal-mag and Bud Explosion just yet, we will wait and see on those ones. I will be adjusting my pH with Dynagro pH up/ down products.
I am starting these girls under the light of a simple 24 watt 7000k smd led panel. It was economical at $25 USD. After they sprout I will move them to the 2x4 tent where they will bask under an HLG 90 watt 3500K quantum board. After a few weeks of growth I will introduce them to my HLG 260 watt 3000K qb.
Other equipment includes a 2x4 Mars Hydro tent, 6" Active Air extraction fan with an ipower carbon filter and my trusty Apera pH 60 tester which I highly recommend. I've had it since November and it has held its calibration perfectly.
The girls were dropped into perlite that was soaked in pHed water and put into my propagation/germination tank and are being misted daily until they sprout.
I plan on vegging for about 30-40 days. Any longer than that and I run the chance of overgrowing my girls. I am aiming for medium sized, well behaved plants this time around. Lol
So I hope y'all will come along and keep me company for the next big step in my ever growing love of Cannabis cultivation.
56 pages ... I'm glad it's Saturday!
Hopefully get this done before we go to the drive-in

Jeez, I wish @InTheShed would get over his man-cold already. We need him!

Yes, Shed and @MrSauga should come and yell at me, tell me what my foolish self is doing wrong.
Does any of this sound familiar to what’s going on with your plant?
Nitrogen toxicity
Dark green leaves, shiny leaves, clawing, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get “The Claw” or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering, but is unique to nitrogen toxicity. You can see a “clawing” leaf in the pictures below (click each picture for a close-up).
Leaves that turn into claws often start turning yellow and dying if the nitrogen toxicity is not treated, much like a nitrogen deficiency, only the leaves will continue to get more and more clawed. Leaves eventually turn yellow or brown and fall off. You can tell if yellowing is caused by too much nitrogen because the rest of the plant will be dark green, and the yellowing leaves will turn into claws first.
The majority of times that growers encounter problems with nitrogen, it’s from giving too much of it to their plants.
Many new growers accidentally give their plants give too much Nitrogen, especially in the flowering stage. This results in dark, shiny, clawing leaves.
Your plant needs a lot of nitrogen in the vegetative stage, and it’s generally hard to give too much as long as you’re not going completely overboard with nutrients. Nitrogen is a big part of what makes leaves green, and is incredibly important to the process of photosynthesis (making energy from light).
But cannabis plants need relatively low levels of Nitrogen in the second half of the flowering/budding stage. While your plants still need N (nitrogen) during flowering, too much N at this stage will prevent your plants from forming buds properly, resulting in lower yields, less potency and possibly inferior buds.
This is why it’s important to avoid any type of “time-release” nutrients or soil (for example, standard Miracle-Gro soil) as they will keep giving your plant a lot of N even after its started flowering.

My leaves are shiny and dark but they are all transpiring well and the leaves are lifted rather than curled.
How's your pH?
(a few pictures can be a dangerous thing with me )

What about...
A cannabis copper deficiency appears with leaf symptoms such as dark leaves that take on blue or even purple undertones. The tips and edges of leaves turn pale yellow or white in stark contrast to the rest of the leaves which have turned dark. In flowering it’s important to correct a cannabis copper deficiency as soon as possible because buds may stop maturing if the plant isn’t fixed up right away. Copper doesn’t move easily through the plant and is considered “low-mobile” which means the yellowing leaves might not necessarily turn green again, but the problem should stop spreading to new marijuana leaves.
Cannabis Copper Deficiency Symptoms
- Leaves turn dark with blue or purple undertones
- Tips and edges of leaves turn bright yellow or white
- Shiny or metallic sheen on leaves
- Leaves may feel stiff and start turning under
- Tends to affect leaves directly under the light
- Buds do not ripen, or grow very slowly
This is what the yellow leaf tips of a cannabis copper deficiency looks like. The most telling feature of a copper deficiency is that the rest of the leaf darkens and takes on a blue or purple cast which makes the yellow tips look bright in comparison. The leaves also often appear shiny and may feel stiff.

Last time I fed my pH was at 6.3. My meter was checked a week ago, it should be right on but I can always check again. Do you bring your pH up in flower a little ? 6.5 ish. I'm in Fox farms so I've been told ad nauseam that I should be pHing between 6.2-6.3.How's your pH?
(a few pictures can be a dangerous thing with me
I was told by @Emilya that varying the ph from the low range to the high end (and sometimes in the middle) every other watering would avoid any lockouts- she told me this while we were trying to figure out how I burned up the leaves on that Northern Lights.

I think this is mobile. Once again I have the shiny leaves and some of the lower oldest fan leaves are a little stiff but any leaves on the plant half way up are normal cool to the touch and supple.What about...

Cannabis Copper Deficiency Symptoms
The pale tips of a cannabis copper deficiency look a little different from nutrient burn, which may start out with slighly yellow tips, but soon makes tips appear brown or burnt.

That's probably what I'm missing or at least part of it.
Well I tried, lol

I certainly appreciate your efforts and you may very well be right. Maybe I'm not reading my leaves correctly.Well I tried, lol
Every plant is a little different,so the GZ may just be a little more sensitive than the other 2...
I burned the crap out of the NL,but the Peyote Critical loved it at whatever my pH really was.
(don't know because my pH pen was crap)

Hey fam.
Holy Hanna these leaves are dark. I knew they were dark but until I brought them outside, I had no idea. Looks like a lockout?
This is the GZ , she has rust spots at the top and bottom of the plant.
Hey @Virgin ground ... that was a nice read.
Your Gorilla ZKittles looks like it is charged with Nitrogen ... I like to do that on purpose so that there is Nitrogen available during late flowering.
I've seen the tips go a bit brown when I've overfed ... and the brown spots I've seen when I've fed a few times with high pH and the Calcium uptake doesn't happen.
When I see white spots or things like that, I always grab the microscope and rule out mould and thrips.
I think I'll head over to the contest threads and see what's happening there lately.
