What deficiencies is this please?

I posted before & got told there was a toxicity on this plant. I gave it plain water the next time, then the same after, but with about 20% run-off. The problem got worse, so the 3rd feed I used half the recommended nutes on the bottle. Problem was still getting worse :(, I just gave it it's 4th feed with a full dose of nutes.
Don't think I need to explain any of this but just so it's there. Heard hard water with general hydroponics 3 bottle set will be fine with Pro-Mix HP. Should I maybe use more of 1 or the other than the bottle says? Or should a full dose probably solve this? Thanks in advance :)

Sorry btw, somehow I only just realized there is a plant problem section. I can't seem to delete this post to put it in the correct spot, I will know for next time.

Or you could stay here, looks like you've got lockout issues, talk about pH?

P.S. GH Flora Nova is for hard water

Hmm, I saw the nova kind but I forget why I didn't want it. Also forgot to put my PH, I keep it at around 6.0, heard Pro-Mix HP isn't considered fully soil less so it needed a bit higher than 5.5 area.
 
I see a ph problem and overwatering.

Some leaves are yellowing base to tip, some tip to base. Rust color spotting. Tacoing down. All signs of unhappy roots and an off ph.
That's really weird if this is the case. I actually feel I underwater my plants because I typically wait a couple days after 1 inch of the top is fully dry. Also Pro-Mix HP is high porosity, my 1st plant was in miracle grow & the only time I saw this exact thing happen was when I flushed at the end. These are near the top of the plant also, the bottom leaves aren't getting this bad at all. As I said above too, my PH is near 6.0. I'm not saying your wrong btw, I would just be very surprised if I'm over-watering lol. Cheers all :)

Under watering will throw the same issues as overwatering... Usually people tend to overwater so I just assume... You know what they say.

If it's mostly at the top, nutrients aren't being delivered, or they aren't there. If they aren't there, most are pulled from the bottom leaves. Since they are good, you are down to ph lockout, salt buildup (doubtful since you water to runoff), or over/under watering.

Picking up your pots is the easiest way to tell. It'll also tell you if the bottom is soggy and pissing off your roots.

That narrows back down to ph (if it's not your watering). Have you tested your runoff?

I don't water until run-off lol. Heard some say 20%, some say it's not needed, I did my 1st grow though. Currently my set-up also isn't good for run-off, its so crowded lol, I can't remove the run-off water to easy. Also whats weird, is both my big plant's aren't doing this. The one with yellowing is a bit bigger, but I did water & nute these 2 plant's the same with no run-off. The 2nd plant doesn't have any yellowing at all, although some leaves are tacoing down with grey dryness to them, closer to where the fan blows though (can't change this it's facing a wall). I have not tested my run-off water this grow when I do have some, I did my 1st plant & was always the same PH, I unfortunately don't have a PPM tester yet though.

In the OP you said you watered til 20% I thought...???

Anyhow, don't care about the ppm of your runoff, just the ph for now.

If you don't ever water to runoff, then there you go. Salt buildup which is causing ph issues, nutrient lockout and pissed off roots.

Thanks :), ya I just meant when I got told its toxicity, I watered it plain water 1st with no run-off, then 20% run-off so it flushes it better.
 
Figured I would add this here & maybe get an answer why. I can't fully remember if I tested the run-off water with this type of soil but I think I did once (was always good on my 1st grow so I didn't want to waste the PH test). I was finally able to water it again & I guess it was a lock-out :(. The PH of the run-off water was at 4.0 or lower. I continued to water it to flush the salts (with nutrients). It takes about 5 litres to get a tiny bit of run-off. A bit hard to know the exact amount I put through since I had to try and fix a 2nd one with the same PH run-off, but it was about 16 litres I put through the plant I posted the pics on. The PH did get better, but it was still around 5.0 or lower :(. So I just put 3x the normal amount (which apparently is a normal flush) & still the PH is coming out 1.0-2.0 lower then what's going in.
Trying to keep the text minimal, but thought I would brief this too. My plant was in veg from Dec. 7 - Jan. 21, with this problem starting almost 1 month ago now. Only 2 months of feedings about, with only a little nutrients after the 1st week as well & 2 times I had slight run-off water anyways. So only like 1 month & 3 weeks of nutrients caused 3x water to not flush the salt? This seem's so strange & confusing :(. Thanks in advance.

How is the plant?

You weren't watering to runoff so salts just build up in the roots instead of washing salts off and replacing with new.

Also, soil buffers so you aren't going to just change it with a couple waterings.

The plant is still getting worse & seem's to be starting on my 2nd biggest one although its from the tip on 1 leaf only. Sorry to I just wanna clarify what you mean. Should I have flushed it with plain PH'd water first before I fed it again? Salt's just keep building up with a nutrient water flush? Reason I did that too is because I didn't expect to need this much run-off to fix this. Also you said soil buffers, I heard regular soil buffers the PH so you don't need to add PH Up or Down, but this is peat based medium (not sure if it balances the PH also). Don't think this is what you mean by "buffer" though lol. Mean it works itself into the medium so it's harder to get out with just 1 watering? Thanks :)

Yea, when you flush, it's with ph'd water and right after a nutrient soak. Then a solid dry. Not let the medium dry out, but let that pot get light.

If you are flushing salt with salt... Well I think you get it. What you are trying to do is rinse all the excess salt out and then put a controlled amount of salt back in.

Buffering is not balancing, it's more like stabilizing. It'll hold a certain ph, not set it accordingly.

So if it's real low and you give it a high oh flush, you'll get somewhere between.

Did you add any perlite or lime to your medium, guessing not the lime.

Ahh, got it. Hope I at least got it out of the lock-out though. By the time this plant gets fixed it'll be harvest time :(, guessing I should add extra time to harvest though because of this lock-out? I did not add any perlite/lime, Pro-Mix HP comes with like 50% of it perlite lol, nah maybe 20% :)

Yea, probably safe to add a little time on.
 
Any heat issues???
Maybe just a tad on the leaves very close to the light but the leaves in the pictures are like 7-10 inches from my CFL light. The room temperature I had near 78ºF during veg. & now it's closer to 72ºF for flowering (yes, the readings are fairly close to the bud's). Thanks again everyone :).
