Some at middle and lower, no real pattern. 1800 ppm flush check.

@brular, that seems like a nitrogen deficiency. It would be useful to know if you are growing in soil or not. If you are growing in soil, then you should feed your plant and monitor your pH. Try to keep the pH within the range of 6.5-7.5 and avoid overwatering. Happy growing 😉

@happynpc Was thinking since ppm is at 1800 ish that it was over fed?

Could you please provide a picture of the entire plant? Additionally, could you let me know what soil and nutrients you are using so that I can better help you?

@brular Your plant is overfed, the burnt tips is a clear sign. Overabundance of some nutrients locks out others, that's why you are having toxicity and deficiency symptoms at the same time. Not much serious damage is done, your plant will thrive if you reduce your nutrients.

@mitsos Thanks for the help. Would it help to flush again? My tap water runs about 900 ppm by itself, use some spring water until plant recovers?

@brular You could probably flush it with that, just don't add anything else, accept maybe some calmag if you need to, but with that high of ppm I would say you don't need to add anything.

I'm guessing you're following the normal GH feed schedule putting you somewhere around 800ppm of added nutrients, you may not need to be adding that much if your regular water is that high. Would be good to get your water checked for what's in it so you can adjust your nutrients. You're probably locking it out.

I used to use my house water with floranova and flora trio and my water was sitting at around 650, and it was kinda hard to regulate nutrients, so I switched to an R/O system, so I'm starting at around 20ppm.

If you can go get drinking water in 5 gal jugs, I would get at least that much and run through around 3 gal and see what your runoff is and get it as close to what your feed schedule ppm should be. Also check the PH, I usually am running at around 6.2-6.3 in my pots using soil like that because it is potting soil and basically like using promix.

If you have to use your own water, test the PH and get it within range, then I would just run that through and get it to your water ppm.

Let it sit for a day or so before you start feeding again, and then feed a bit light for the first time, check runoff and see where you're sitting, then adjust and feed as normal.

If you haven't been doing any runoff, then you are most likely locked.

All of this is is my opinion/experience and someone else here might have other solutions.
