I’m betting you’re battling a lockout situation due to excess N….

Excess N locks out calcium I do believe….
Despite the fact I will never be able to memorize this, it's called "Mulder's Chart" (don't think it has to do with X Files :P)

Looking at the chart this fertilizer product seems so senseless....

Adding N to the Cal/Mag boosts the plants demand for Mag, so it will end up with surplus Cal, what will lockout Mag? Who invents this shit? xD
 
Look at the amount of N that product contains! (Upper right corner)….

I think you stop that immediately…..

If you need to supplement magnesium use Epsom salts….

If you need calcium look to water soluble gypsum…
After some more thinking, this totally explains everything...

I used this fertilizer because I suspected Mg deficit in first place.
The additional "N" in this fertilizer will raise the plants Mg demand even more.
Potentially worsening the Mg deficit and culminating in Ca surplus -> Mg lockout.

Operation successful, patient dead... -.-
 
just discontinue use, and take it easy on them and they’ll finish fine….

One other thing…. If you want to go full organics with less issues….increase your pot sizes. Organic works best with a big battery of soil…. That way it won’t deplete as much and it’s easier to stay ahead of. Alot of us are in 7.5 gallons and up….personally I’m using 10 gallon planters…..some go as high as 15 or 20 gallons. Soil gets recycled as long as you don’t use chems. Just something to think about….

Yeah won't use it again... perhaps just some P + epsom salts next... if I had such a "poison" warning sticker I would stick it on that fertilizer and keep it as a warning reminder xD

Just wanted to try how it would go with smaller pots. Last time I had ~5 gallon pots. This time I wanted to try with ~2 gallon pots, so I could have more plants -> more variation.

The next grow will be totally different. Until now I just did autoflowers, next grow will be with @Antonio_DutchPassion 's Slush Mint Cake BX1 regular photoperiods and I'm going to produce a ton of seeds with them in the first step...
