Need help identifying issue

[TheStickyEst]

Looked at my plants this evening and found this. Is this nute burn? Only one of three plants is showing signs like this. This is my first attempt at growing and I'd like some help with identifying what I'm dealing with. Thanks guys and gal's!

I think that's either Phosphorus or Potassium def.; but not positive. I think you just add something like Terpenator 0-0-4 to clear it up. I haven't had this issue. Only seen it before, so let someone who knows for sure chime in.

That is K def - top dress with wood ash or as BB suggests, Terpenator which is basically K/Mg

Hold the phone .

Maybe we should ask some questions first???

Get a better picture of the whole plant. I can't tell but it looks a bit pale. Could be the lighting though.

What are you feeding it?

I'm using all this ph'd to 6.4 last feeding if I remember correctly.

Gh Flora series
Micro
Grow
Blom
CaliMAGic
Floralicous plus
Following the aggressive feeding chart for early growth plants.

Are you adding the cal-mag first?
If you don't it can cause lockouts. It will cause precipitation of potassium making it unavailable to the plant. Adding too much cal-mag can also cause issues like potassium and mag lockout.

Since your plant is young and you are feeding an aggressive schedule this is quite possibly what we are seeing but it's also possible that you have a plant that is a heavy feeder and is demanding more nutes.
This could be why only one plant is showing issues.

Also make sure that you are pHing your mix as the last step before you feed.

I'm not sure what you mean by first? I mix all nutes together including the calmag and then ph to 6.2-6.5 also this was the first watering I included the calmag to per the manufacturer's recommendation.

You should be adding your nutes to water in a particular order and mixing in-between.

Always start with silica if you're using a silica product. If not then it would be cal-mag first and then your nutes etc.

If you don't add cal-mag first it can precipitate the K (potassium)salts out of solution.
This will make K unavailable to the plant.

Is there a helpful list of an order of operations so to speak ?

Silicon or CaMg always go in first (though as my tap water is crap, I do add a drop of concentrated Citric first off to nullify the chlorides) Then micros/root juice/boosters etc, then your feed (eg A then B) and let stand for a few mins, then adjust pH I have always done it that order and never had any nute issues

Got this from GH
If you are referring to our most popular line- the Flora Series- you will mix in the following order: CALiMAGic, FloraMicro, FloraGro FloraBloom and then either Liquid KoolBloom, or Floralicious Plus, the last two do not matter which order they come into the mix.

Thanks for the assistance guys just a newbie here and I had no idea that nutrients had an order of operations.

Great!
Things should improve pretty quickly.
Those damaged leaves will never heal so look at the newer growth to gauge health.
Let her use them up for now. You can safely remove them when she is a bit bigger.

I agree that the damage so far looks like magnesium deficiency and VG seems to have you sorted out very completely. I simply want to add this about pH adjustment. There is a huge difference between 6.2-6.5 pH. Please be more accurate than this, and carefully adjust your pH each time to exactly 6.3 pH. This is the point where the most nutrients are the most mobile in the soil, and a great point to start at so that when the soil causes the pH of the container to change, it will drift upward through the entire 6.2-6.8 pH range. Many growers even today after many years of open exchange of information about growing this weed over the internet, don't yet realize that pH is presented as a range for a reason... it is not just one number we are shooting for... aim for the bottom of the range and because of the high base pH of your soil, you will drift through the entire pH range as the soil dries. Also, if you start at 6.5, then the drift will let your grow see only the part of the range from 6.5-6.8 pH. Not only do you miss out on some of the heavy metals most mobile at the low end of the range, but your time within the usable range is much shortened since you started in the middle, and the amount of time your plant is exposed to available nutrients is cut in half or worse, depending on the drift rate.

Thanks for the advice! I ordered some terpinator (will be here Saturday) hopefully the plant can wait till then. Will also start following your advice Emilya and ph to 6.3. Should be dry enough Saturday to water with properly mixed nutes (this time) including some terpinator to try and resolve this issue!
