I would have to say the p/k 13/14 is your problem just like Soil did. Just too early for it. You have made some adjustments so be patient. Cant fix things overnight...........
It wants more P in proportion to N and K. Actually the K in a plants diet is one of the main driving factor in how it uses the other 2......Don't obsess over the NPK values at this point. In a perfect world, the plants want more P for flowering, but a good general purpose fert will work just fine. Fine tuning your growing process can be done after you get the keeping them alive part down pat.
that is not normal at all ! 925/ 1.2 ? thats comin from the sewers of new york city ! AND your low in ca/mg ..... wow.If you are using tap, you might ask your water provider for a water quality report, or get one done on your own tap. I think that's a better $20 investment than first running off to the hydro store for a lot of folks. My tap is pretty extreme, yours may not be, but you won't know unless you check. Mine is 925ppm, 1.25ec, high in sodium, high in bicarbonates, low in mg/ca. It's nice to know what you're working with to plan your watering/feeding/medium.
yea ive had hundreds of those.They're not gonna die. They'll look like it tho. I got some good smoke off this wretched thing and they started looking bad right at the same time. You just wont get a whole lot. I think I got about 2 zips from this one. But if you keep foliar feeding like that, you risk mold, and getting nothing.
vinegar can kill plants.thank you wyteboi for all your words! I recalled something. I used twice apple vinegar for lower water pH, twice citron and once white vinegair. pH was OK after that, but I have no idea if vinegar can mess with plants....
It's below ground co-op water source, aka well water. I'm pretty sure from the low ca/mg, and other numbers that they are softening the water and the sodium is a byproduct of that process. Hard water is common in this area.I have some leaves showing similar spotting and yellowing as yours, but in veg and not nearly as wide spread. For me, I'm thinking it's a problem with potassium deficiency due to high sodium levels. I've got a water analysis on my tap and I know it's high sodium to begin with which I think is a by-product of their water softening process (I really should talk to them about it to confirm my suspicions from the numbers).
I've got a couple extra plants I've kept in smaller 6" pots as backups and for experimenting. I did a runoff test last night, not using a perfect runoff method as I don't have distilled water handy, but my 8.2ph and 1.25ec tap water was running off at 4.8ph and 7.8ec. I ran enough water through, maybe about 3 solo cups worth, till runoff was more around 6.1ph and <2ec. I finished with a mild watering of 20-20-20. In my situation I think I need to either do a regular 10-15% runoff every watering or maybe a monthly leaching on plants that have been in the same pot for some time. We've had a terrible drought this year, but I'm thinking of starting to accumulate some rain water to work into my regimen. I'm just offering this up as an example, this might not be your same problem.
