What did my plants have an issue???

[Cringer]

Ph is 6.6 from run off and the solution... Nutrients biobizz grow and Bloom! I think i give not enough bloom Nutes after the Strech (2ml/l) so I run very very quickly in a deficiency I don't know what's going on it looks like a phosphorus/potassium deficiency but it is hard to identify. I road a lot websites to deficiency problems and for me it is potassium and phosphorus and maybe calcium..

So, I double know the bloom Nutes to 8ml/l and I give 1 teespoon dolomite lime /l water I road this in a forum. I hope someone give me information here what's wrong is day 47 from both plants.

Hi, mote info is needed on your setup, there is a form at the top of the infirmary, fill that out and we can be of more help... lighting, temps, rh, medium etc...

It does indeed look like a cal/mg defficiency, but there are several possibilities as to the cause, not knowing the details of your grow. I'll give a shout and get the doctors, but they're gonna need the aforementioned info!

Hey @Waira !!! Wanna give this a look when you've got a minute?

Temps are 22-26 at day night temps 19
celsius

Humidity 45-55%

Soil: Plagron Light Mix

Lights 3 x COB led lights 55 Watt x 3 = 160 Watt

Thank you!

So what's wrong??? I hope the most yield are not destroyed ;-(

I know where the problem comes from!!! I calibers the Ph pen the last time I did that is 1 years ago so shame on me.... The Ph pen is know ready for the right Ph and 1 hour ago I have tested 1. The nutrients solution 2. Tap water. The Tap Water I have has a Ph from 6.5 I don't know why it is so low last years the Ph was 7-8.5ph so I was shocked! The nutrients solution i mixing has a Ph from 6.2 holy Fuck know we know where the problem comes from and I need to say I put bevor I have tested dolomite lime in my mix and the Ph is not higher than 6.2 without the lime the Ph is maybe below 6 and that's Coco Ph Fuck but know we have the problem guys what you think?

I don't know how I can lift the Ph up to 6.8 so I give tap water first bevor I mix a new solution...

How I can bring the Ph up baking soda don't work!

What are the npk values and recommended dosages of your nutes.The picture with the small spots looks like typical cal/mag defiecency.are you using calmag?

I using biobizz nutes 5ml bloom 2ml grow /Liter
I don't have cal/mg

Cal/Mag is very important when growing weed and should be given at every feeding once flowering has started.It's even more important if your running led lights You can still use it now and it should help with those spots but once they get spotted they will stay that way so just remove them and hope it doesn't spread further.

Where I can find cal/mg? Not every store has them.. Maybe Remo nutrients cal/mg? I want to go next with Remo line but can't purchase every Nutes from him! I want to buy grow, bloom, and micro Nutes. Do you think it is better to buy cal/mg and not grow ore micro???

Here some leaf pics they fall down and pics from the downside both plants.

:smoking: Andi, check out the Defc. Pic Depot right here, in the highlighted section above this one,...
Biobizz is very mild stuff, easy to underfeed, and sometimes you get micronutrient defc,.... which i think this is, at least in part,... worst leaves are near or at the top, right? If so, this might be Mn defc., very rare, but these symptoms fit it best,... some P defc. may be affecting over all color too,... pH lockout happens when pH is near 7.0+ pH, but with the iffy meter accuracy, we don't know for sure pH is OK,.. And the best way to check in-pot pH is with a quality pH probe, like the Accurate 8 (Control Wizard),... That said, you pH meter is likely ruined.... if it was stored improperly, not in the right storage solution, and kept moist always (short dry-outs are recoverable in function), not calibrated regularly, then the electrodes are damaged beyond repair likely, and no reading from it is to be trusted,...
Most micronutrient supplements will have Ca and Mg too, along with the true micronutes (Ca and Mg are secondary nutes, not micro's),.... Fe, Zn, Mn, B, Cu, Mo, Cl etc,... question is what you can get,... my choice is Earth Juice Microblast,... Mn is immobile within the plant nad like most immobile nute element defc.'s, they are a bitch to fix,.. foliar sprays work best, fastest, but in-pot treatment is needed too,... In any case, this isn't either Ca or Mg defc.....
Your water is very unlikely to have dropped an entire point+ in pH! That's why I think that meter is toast,...
