Hydro coco sick flowering plants urgent help needed

Hey guys I’ll keep this short for now as I’m in a rush to get to my local for ph down. I will elaborate more later on but I’ve been having this problem for about a week now, it’s mid week 5 of flower and I just can’t figure it out. Really starting to worry, symptoms are worsening and growth has been at a halt for a week now. Hoping someone can identity this with certainty from previous experiences.

I understand that it is hard to identify a problem when there is so little info given, like I said I will elaborate completely in a few hours once I get everything done. Just wishful thinking I guess, hoping someone just knows!
Thanks a million in advance for any help anyone can give, massively appreciated

the big pic looks like bugs on leaves check closely under leaves looks pretty dark green too maybe to much nitrogen might help with a bit more info strength of feed and so on

tips curling up is usualy temprature related, that and too much nitrogen i think

Nitrogen toxicity.
Are you feeding daily to substantial run off?

Thanks for getting back lads. So as for the bugs you’re on the money there. I’ve got another 17 half size girls in the other half of my flower tent, but being so busy lately some spider mite managed to settle in and colonize. Hell of a mission getting on top of that but should be in the clear now as long as I remain vigilant. But as soon as I got over that issue I gained this one..

Temp in the tent stays reasonably stable, fluctuates between 20-24 Celsius, give or take the occasional degree here and there. RH sits at 45%-55% thanks to the $800 dehumidifier I lost an arm and a leg for..

Nitrogen toxicity, damn. I hadn’t considered that really as my nitrogen is relatively low in my NER. I’ll drop my feeding schedule below, but I thought nitrogen toxicity typically showed as tips turning down (clawing), maybe a combination of that and other things.

I have been having issues with my res PH too, mixing to 5.8 and stays stable for the couple hours before I pack up for the day but then the morning comes and the guardian shows the res sitting at 7.2-7.5!! Still troubleshooting this but currently wondering if it’s the PH down I’ve been using, been getting it from my local home&hardware and after some research today I was made aware that citric acid may be the cause, generic branded citric acid at that. Thoughts?

In terms of runoff I was under the impression that I was likely feeding to much more runoff than I should probably be. 17 plants in air pots, 7 are in 13L pots and 10 in 11L pots. Total of 201L, feeding about 60L per day for about 20L runoff.

Week 5 feeding schedule (per 100L):
Cyco Silica 20ml
-(1.5 hour wait)
Trace Elements (hardware store brand) 20ml
-(30 min wait)
Flairform CMX (Ca,Mg,Fe) 35ml
-(30 min wait)
Canna coco grow A 30ml
-(1 hour wait)
Canna coco grow B 30m
-(1 hour wait)
Cyco swell 30ml
-(15 min wait)
H&G top booster 30ml
-(10 min wait)
Cyco Sugarush 30ml
-(10 min wait)
H&G Algen extract 10ml
-(10 min wait)
H&G bud xl 25ml
-(10 min wait)
Superthrive 9ml
-(10 min wait)
Flairform grostorm 10ml
-(10 min wait)
Floramax drip clean 10ml
—-PH ADJUST—
H&G root excellurator 3ml
PPM @ 450ppm. Feeding once daily just before lights out until roughly 25% runoff.

This is my first experience with hydroponics so any and all advice or suggestions will be muchly appreciated

Not surprising you're having issues with all those additives you're using........wtf.
Why are you adding additional trace elements?
All you need is the base nutrients.......Canna A & B........the rest is nothing but a problem causing waste of money.

You're dumping 12 different products on your plants and wonder why they are having issues? You do not need all that stuff. Overfeeding is what causes more problems than anything. A balanced feed from start to finish will grow healthy happy plants. Don't get caught up in all the cannabis product marketing nonsense.

450 ppm sound low to me i run at 1400 ppm all the time ill do half strenght for first week then upto 1400 ppm

Yeah I’ve been wondering that lately, but just confused as to how I could have toxicity when feeding so low and so much runoff, I’ve been flushing daily and following with a 250ppm feed for 3 days now and not seeing much change. Might be to soon, we’ll see in another few days I guess. Just really getting worried now as it’s about to go onto week 6 of flower, so much time and effort, and so little chance of saving the harvest. Still have no idea what is going on, this is gonna hurt me :/

1400ppm, are you running coco?

Sorry for the late reply, I did read your replies just so flat out with everything I’m truly struggling.

Yeah I’m feeling that now, just at the time of setting up I had some coin to invest and wanted to throw everything at it to try iron out as many kinks as possible to learn as much as I possibly could before the next crop (Amsterdam strain, hell expensive and lots of it)
Reduced my list to this:

10ml cyco silica
20ml flairform cmx (calmag for coco cation exchanges)
10ml canna grow A
10ml canna grow B
23ml cyco swell (bloom booster)
7ml cyco potash plus (to complement swell)
10ml Multizyme
3ml superthrive (vitamin b supplement)
10ml Floramax drip clean
-Ph adjust-
3 ml H&G root excellurator

Does that sound any better?

Also treating with great white mycorrhizae and anti-matter molecular enzyme bioreactor in attempt to save them. Seen the same problem many times online now, and this seems to be likely the only way to fix the roots. Not looking sludgy but not healthy and white either..

shit dude this is starting to feel real bad, haven’t ever failed before, I’m losing hope..

Any feedback and/advice here will mean the world!

Are you following a drain to waste feeding chart or whats on bottle

You wasted a whole lot of money on nutrients you didn't need.


10ml cyco silica
20ml flairform cmx (calmag for coco cation exchanges)
10ml canna grow A
10ml canna grow B
23ml cyco swell (bloom booster)
7ml cyco potash plus (to complement swell)
10ml Multizyme
3ml superthrive (vitamin b supplement)
10ml Floramax drip clean
-Ph adjust-
3 ml H&G root excellurator


And this snake oil is an absolute joke "anti-matter molecular enzyme bioreactor". I thought you were joking until I googled it and saw that it's an actual product. They sure sucked you in with all that overpriced, cannabis specific snake oil in a bottle.

I have nothing further. The results you got from using all that crap speak for themselves.

Good luck with your future grows.

Jacks for the win!

It really is that simple.

Just a few more pics for clarity.

1 & 5: One random head doing some weird ass shit, swollen up and above the swollen part the growth is kinda odd (pic 2), below the swelling it’s normal though..

3: roots. Not sure what to think of it, should I be worried? Opinions would be appreciated.

4: one random head doing.. Well whatever that is.. Looks like it’s been topping itself while I’m not around lol first time I’ve seen this.

6 & 7: more shots of the damage to leaves, almost half the crop showing these symptoms but not sure yet if it’s progressing or if the treatments are taking affect.

Opinions anyone?

For sure.

MY PH became unstable from just reading the exhaustive list of his ingredients. Lol

Nah definitely not the bottle recommendations but also not a chart. I done the maths at the beginning to determine the NER I wanted at each stage and the amounts of each nute I would need to achieve those. Then I dosed weak to start and raised until I reached a comfortable level. But the past couple weeks has thrown me so many curve balls that I’m way off the rails, gonna have to re-evaluate after I get a grip on these issues I’m having. Just trying to focus on not losing the lot at this point.

Why do you ask? Any advice or recommendations you can offer?

Stop dumping so much stuff on you're plants? You're poisoning them.

Jacks, I keep hearing this but it’s new to me. Can you elaborate? Also are you running coco?

Thanks by the way!

You only want to hear about some other product you can dump on your plants to fix them. The solution is to dump less. But apparently that's not the answer you want to hear.

Good luck.
