what are/were your watering habits like? If you are letting it dryback too much you can cause ph issues/nute issues
Still unsure as to what is going on, need veteran help PLEASE

@curious2garden , what do you think? Early septoria? I didn't
Yea that's alright. I used to water to just where it would drip out a lil from each hole, just to know I saturated the entire volume of soil. You just don't want to wash out nutes and microbes.
I thought it might be a P def from lack of light penetration with necrotic spots, starting to decompose. He's running 220W and she looks like a nice size plant. But I've only seen Septoria in pictures, so not sure.

It does look similar but because I have another plant thats doing great, I don't think it can be that right? I think this one is actually low on both nutrients and the ph is slightly out of whack exasperating the issue. Causing multiple problems. Big sad but I'm gonna keep trying with it. Thanks again everyone.

Its pretty full size actually according to barneys farm. Its been growing great even with this issue starting. I think everyone is right. A little bit of a low ph and, me making the problem worse flushing nutrients out. I'm gonna let it chill now because I ran a ton of water through her, the last gallon I put a heavier feed in to replenish anything I might have washed out. Hoping for the best anyway ill keep chugging.
keep it real.

Grab yourself some down to earth lime add 3 table spoon(if using 5 gallon) to the top of the soil and work it in and water it in. Start a feeding regime.
i don’t recommend the droplet ph testers, everyone sees color differently and that could make all the difference.

Those spots in the 2nd photo look a bit suss to me. Can't say what exactly, but I don't think it's nutrient related myself. The colour is off and there's signs of necrosis, rather than leaf cannibalization imo.
If it's an infection, it's likely down to your environment. Likely too humid and too cold.
Watch for leaves the plant's cannibalizing, like the ones in your first photo. Plant will make use of any shaded leaves and cannibalize them.
A couple leaves are completely gone in 1st photo. You should be removing them, as it's an invitation to pests and disease.
Looks quite dark, if not a bit wet on the surface soil too, judging by 1st photo, so watch you're not watering them too often.
My own self is saying to remove any leaves with symptoms, if its just a few.
Keep the environment in the right parameters.
And give it several days, before deciding to make any changes, like introducing nutrients, amending soil etc.

For sure. Same for me. Maybe it is just necrotic spots.

i dont know why people are telling you to check run off ph thats just bad info. theres two things that matter the ph of your nutrient solution when it goes in, and the ph of your medium i would personally check it a few hours after watering with one of these as well as the following day and so forth until your next water it will give you an idea what the ph is actually doing as it will likely drift. i also think its low ph as well do you have any dolomite lime? you can add a table spoon ontop of your medium and water it in. itll help buffer the mediums ph. you can endlessly speculate on what the problem is but until you can determine whats going on i would get these.
keep it real.

Checking runoff ph is bad advice? How please explain. if you water in at a ph of 6.5 and your runoff is 5.5 you know it’s low and not in an optimal range.. it won’t give you the exact soil ph but it will give you an indication of a problem as to what is leaching out.. ppm would be salt buildup and low ph indicating soil is outside of range.. and I do agree with you those testers are great. I own one.

I'm having a lot of fun running 20% potting mix to 80% perlite, have to say. There's just enough water left in the potting mix to tie me over to the next day. Drain-to-waste style.You may want to consider switching to growing in coco? Reason I say that, it's much much easier in terms of "set your parameters & go"; you don't have to worry about overwatering coco. You just have to give the same level feed every day, which eliminates a lot of guesswork.
The manner in which you're growing is already kind of coco-style, including the haphazard addition of calmag; in coco, you're most certainly gona need to add that. Best of luck either way
Actually finding it easier than coco coir. PH seems more stable and I don't have to water as much.
Been doing the same for about a year now. Was using Canna Terra Pro, but now using Osmocote. Much cheaper and works just as well.
50/50 mix for smaller pots and seedlings gives me a couple days worth of water.
Just saying, I agree with you, the manner in which you grow matters a lot.
I kind of feel OP needed more aeration, but I neglected to say. It's too late in time.
If OP's going to be treating it in a similar fashion to dtw hydro, the water holding capacity could be a bit high.
No full strength nutes imo and maybe water between.
I think it's risky giving a proper feed right now.
Better to just leave things for a bit, let the soil dry, then decide where to go imo.

because testing the run off ph doesnt tell you the ph of the medium. its like when your driving your car and you can hear the engine making a funny noise. the noise will tell you theres a problem. but if you want to actually know what the problem is you actually hafta get out of the car and look.

Well too late for that haha. I fed this morning. She seems okay for now but these spots are still developing. Just gonna let er go for awhile now and hope for the best. Big sad if it ends unwell.

You'll be right. Just take it easy for now. Good luck.

I’m a heavy duty diesel mechanic so this is a great analogy my friend! If you pull the drain plug off an engine and you see metal in the oil does it tell you the problem? Or is it enough. information to let you know you have a problem?
Ffof is a peat based soil, peat has a ph of around 4, some higher some lower.
The carbonate hardness (lime) gets washed away or loses its effectiveness on the peat OR enough was never added from the factory.
The ph crashes slowly, iv seen it time and time again.
coco is an inert medium the ph you add will generally stay with some swings similar to a DWC system, peat is so acidic It will always fight the alkalinity of the soil.

It never too late to un-water, when you can put a sock on the end of the shop vac nozzle, and suck most of the water right back out of the pot\bucket of soil through drainage holes.
What do your holes look like anyway? I see you have 2 buckets sleeved together.. but doubt you would let it sit in any of the runoff, especially since you were worried about flushing out extra nitrates.. Still, your cutting off from being able to pull in extra oxygen through any holes from below if you leave it that way all the time. Things could get funky down there not being able to air out. Root rot, etc.. Or do you just use the second bucket only when watering?

Yeah that was just like that for the run off, and I should have plenty of drainage. I drilled holes all over the bottom and sidesIt never too late to un-water, when you can put a sock on the end of the shop vac nozzle, and suck most of the water right back out of the pot\bucket of soil through drainage holes.

would this work for a ph buffer? To raise it? It was all I could find locally and seemed okay but it has nutrients in it apparently.@keep it real. @BongerChonger @Hollatchaboy @curious2garden
I'm gonna wait to apply either way, the tips of the new foliage are burning back but don't appear to be spotting.

Yes it will work and raise ph but you need an idea of how far off the ph is before you just start adding. You can’t guess an amount and go blindly.
