Can’t figure out what I need to do...have increa...

if adding cal-mag doesn't help or stop what's going on, it's more likely lockout as the cause. you need to know your ppm of what you feed to help eliminate possibilities... I'm going to guess P or K is too high and you are locking out Ca... This is FAR more common than Ca-deficiency.. If your fertilizer doesn't have a good Calcium portion at appropriate levels, there's something terribly wrong with that companies fertilizer. It is an essential component and should be at an appropriate level to start with minor adjustments needed per seed. So, do some research, consider recent behaviour.. make sure pH is in proper range for your substrate (~6.5-6.8 for soil, slightly lower in soilless, and even lower than that in pure hydroponics - technically soilless is hydro, fwiw, but not for the reference here). Do these things before making a choice based on what i tell you or anyone else. if you see Ca ppm is ~100, it's not Ca-deficiency... adding Ca will portentially make the problem worse by locking out other nutrients due to overdosing with Ca. It's all a balance.. it's all relative to ambient environment... have fun :) nute->ppm calculators exist online. I have one that works well for dry nutes mixed, but only 80% certain i have it calculating for specific gravity of the liquid nutes with w/w values... it's linked in my GD profile comment section, if you want it. If you use a web calculator, make sure it accounts for specific gravity or it'll be so far off that it's useless trash information.

hey there YoungWeave, you've got N toxicity which is due to too too much N, make sure you read all the lables and find out what's got N in it and cut some N out. You also have calcium issues, and this can be from any number of things for example too much calcium too high pH too high eC and even too much light scedule. Hope this helps ! 🚀
