What is wrong with this blooming plant?

Some TDS meters are 500 scale, some are 700, there are others, but those are only the common scales. All TDS meters are reall EC meters, the description of the different TDS scales used made no sense to me. Dumpster fire.

I think GHE micro contains some cal/mag but not much.
Hey,
Not gonna argue about the advice bit, I think I did and looked into a lot of the things people gave me advice to do but if you're in a differnet opinion - so be it. Yes, i'm not a master grower but I do think I understand the relationship with pH, EC and water uptake - to a basic degree.
I've got a oscillating fan that runs on a random timer and by that I mean it turns on and off randomly during the entire day. I'm running GHE flora trio (micro, gro and bloom) along with their cal/mag supplement. I'll get a whole pic of the plant up for ya.
Yeah, I agree but I don't really know what to do since i've tried quite a lot of options and wasted quite a lot of nutes etc. Sure I agree that the leaves belong in the fires of hell but the plant doesn't seem to be beyond saving as of now.

My EC/TDS meter runs on both 0.5 and 0.7 scale. I measure EC since it's universal and it can get confusing using the TDS scales when talking ppm.
I agree, when people post the ppms of their plant and not the scale, a lot of issues can be brought forth. That's why i'm just using the EC values (in mS) so there can be no discussion about it.

Man, I wish I had some good advice for you, I would be concerned about my roots. Sprry for being a dick, thanks for responding in a humble way. My instincts say K deficiency or an imbalance of K against maybe uhh? I am no master, either. I am sort of thinking maybe your roots aren’t getting enough oxygen.

Yo, I was tired last night. If you are in the USA it almost certainly uses the 500 scale. We can devise an experiment to test it, if need be.

It's fine dude. I'm quite pissed at this myself, banging my head against the wall. I've replaced the water and put in 50% of the full lucas formula along with some calmag. But we'll se what happens and if anybody else has a clue.
Also, i'm running a 3600/l hour airpump with 2x 150mm stones (1 in each bucket) so that should maybe be enough.

@mixchemical - I always experience this exact phenomenon and have never gotten to the bottom it.
Rapid PH drops during flowering that start 2 to 3 days after a rez change. Different nutrient lines. 100% RO water vs 100% well water vs a mix of both RO and well water. Low PPM feed, high PPM Feed. Sterile and non sterile. Makes no difference...I've tried all of the above combinations and it just doesn't matter. I just do the best I can. For example, if I know that PH will likely drop 4 or 5 basis points during the dark cycle, then I'll PH up right before lights off to like 6.2 and sure enough, PH is 5.8 when lights come on. The only advice I can give you is to change your water more frequently and just do the best you can. My PH levels only stay steady for 2 days or so following a rez change.

yes let me know what to do. apparently my plants are very small for 53 days of veg so wondering if maybe i was just giving it wrong amount of everything from the begininng using the tds meter i have

Really? Is it like that with all the strains you grow or just one? This is the first time im running into this , all the other grows have gone quite fine but nothing like this.
I just changed out all the water, put in 1/2 strength of the lucas ration so 50ml of micro and 100ml of bloom. No pH down - i'm just gonna let them drift down from 6.6 and see where they end up. Really frustrating because you can't learn when you're chasing a ghost.

Ghost as in what is causing the issues i'm having. I've got no clue and nobody else seems to either so I call it a ghost.

Yeah...I hear ya man. I don't have a lot of hydro runs under my belt but this has happened each and every time. And nope, nothing to do with strain either.
I try and take a negative and work it to my advantage. For example, we all know that if you could only pick one PH to live at, it would be 5.8. However, it is very good to let the PH drift below and above that. Try writing down your PH a bunch of times thruout the day and try and find the patterns that you can predict and then just get out ahead of it.

It happened every time you grew in hydro or just during every grow? Just want to know out of curiousity.
I get what you're saying, i'm in the process of putting together an automated pH dosage system, it should help quite a bit. Still, seeing the plan suffering because of something and not being able to fix it really sucks.

Just in hydro. But I also never really had problems like you are. I never had the terrible leaf damage that you're seeing.

Last update for me in this thread. pH went from 6.6 down to 5.5 over the course of about 24h, no signs of it stopping. So i'm just going to give up tbh, wasted a lot of time, energy, nutes and money on her and she's not giving me any indication that it's getting better.
Thanks to all the tips and info that you have supplied me with. Cya around the forums!

You must be using RO water. I can't imagine the ph would just keep dropping. It should find a happy spot. So that was 50 ml of Micro in 13 gallons or 10 gallons? When i use Lucas 5/10 or 8/16 in well water my ph stays stable around 6 indefinitely. I would actually .like to see a little more swing. Your plants don't look bad. I think your ph meter is wacky.

I'm not, using water straight from the tap. First i dosed 8/16 like you do, which made it 100ml micro and 200ml bloom. Then i dumped that out and put in 1/2 strength (50ml and 100ml respectively). I've got two meters to check against, granted they are both the same but the wife has 0 issues. I dont think it's the meter. Calibrated them both and they both show the correct ref. value.

Exactly what fert are you using?
