Please explain what this means
"..running around 1320ppms (ppm700) per feed currently"
and please show top and bottom of the same leaf with the black spots not just the bottom
Thank you for your explanation. Yes you're absolutely right, there burning up!When mixing nutrients you measure the ppm of the mix along with the ph. There are a few measuring types of ppm. 500 and 700. I measure in the 700 range as that's what my nutrient line goes by. I had in the earlier pics. At that point the leaf looked fine on top. Less worried ahout the black spots now and more worried about my latest pics I posted above. I'm thinking it's nute burn. But after a couple of flushes, shouldn't the nute burn spread be stopping?

Thank you for your explanation. Yes you're absolutely right, there burning up!
but you've got a few things going on so I'm trying to get through your post and see what you got up
in the meantime if those were my plants I would be flushing the piss out of them
I wouldn't put any newt in and I would never feed by a newt company's program to begin with
I'm trying to figure out how are you growing, I'm going to go back and reread later this afternoon so I'll be back to talk with you about this
I want to know about the black spots what the black spots look like on the top of the leaf too, not just underneath, that too will help
please look up 'slurry test' and properly preform one as soon as possible and post your results;
right now I recommend heavy flushing and I need you to tell how often you're feeding nutrients and how strong you feed at
also my PPM metre reads on the 500 scale, not the 700, how do you know yours is not reading on the 500 scale as well? What type of metre are you using
How hot is it in your flower room, looks a bit like temps are to hot, makes plants drink more than they need to and burn.
7 pH and 140 PPM are not correct results for slurry test, so I feel something is wrong there
in the meantime if those are my plants burning up in those above pictures let me tell you the steps I would do right now
I would flush at pH 6.5 each plant with three times the pot volume (eg. 3gal pot = 9gal h2o) which is the first or second time I've ever recommended this heavy of a flush, but they need it right now to stop the burning of the plant
If you've already flushed the plants please say when and how much water you used and what was the result of the runoff, pH & ppm?
I would look up 'slurry test' and perform one on my soil immediately and post the results
Also above you mentioned slurry test but do you have it confused with runoff test I'm wondering??
I have used Fox Farm ocean Forest over 4 years now so with the requested info I believe I can help you; I will be back later today
Slurry test use 2 to 1 , water to soil, take it from halfway down or so, not the top stir very well, let it sit 15 minutes stir again and then take both readingsThank you!!!
I have fox farm as well
Yes I think I have slurry and runoff confused. I've only done the slurry test taking soil from the top, mixing with same amount of water, etc. Not sure what a run off test is. I have an idea but not sure how you take that. Just grab and put into a cup and test as it runs out?
When I flushed last few times I only did a gallon of water. I strarted flushing as well a few weeks ago first because my water started sitting on top and my plant stopped taking up much water
After the flush that problem went away.
I last flushed yesterday with a gallon. I have zero runoff. I'm a newb so didn't know you flush with more. So to ph adjust, my water is normally 7-7.5ph, and to bring that down I have Herculean Harvest bone meal that brings the ph down. Otherwise I need to purchase some ph down. Never had an issue with ph tho doing mixes. Maybe more so just flushing because I'd need to add that herc harvest to lower it. I also have photosynthesis plus that I use as a tea.
My ppm with tap water is around 350ppm. Reverse osmosis water shows 0. If I mix the 2 together then it's around 140ppms.
