Help with diagnose

Hi everyone.

Since 2 weeks some of my plants started to slown down in grow and having spots and curly leafs. Mostnof them are big and nice ones. Some are medium which realy slowed down about week ago, less than some are small ones where one of them suddenly on her own died 3 days ago and least are reaaaaly small from begin.
Thanks for any help

some of those pics would be better with the lights out

my first guess at a glance is nute burn too much nutes
but it could just as easily be nute deficiency
we wont know until we check out your nutrient mix ratios

what type of water system is that? flood and drain?

what fertilizers and how much of each per gallon

whats your ph range and ppm/EC of the nutrient solution

whats the ppm/EC of your source water and starting ph

how long have they been in veg

how long before you plan to flip to flower

That looks like a severe ph issue to me. Whats your ph?

Its 6.0-6.3 ec 1.2, had 1.0 before, after weekly wather changing ive done 1.1 and put 80ml calmag and raised it to 1.3

yeah, but what is your nutrient source?

Ph in a tap you mean?

Ohhh, my bad. Im quite new to it. Im using canna aqua vega

Here you got............

Ive noticed min temp at 21 degree cells. 26 max. Would that be affecting them?

Could have an extra chromosome?
First are you mixing a&b to the correct dilution?
How often with cal mag and what else are you putting with it?
How often do you water?
Do you have a dehumidifier?
Lets start there.
If i had to guess ide go with mites of the broad persuasion. Are your leaves glossy?

Not sure about chromosome
Yes, im sure i do.
I did put calmag once so far, at monday.
I do wather 4 times when lights on 2 times when off. Its been set for 15min feed, but ive changed it to 10 last night to see if that will help.
No, i dont have dehumidif. Humidity is usualy 40, so i do spray bit of clean 20 degree cel wather to raise humidity. To 55-60. Twice a day on average.
Leafs do not look glossy. I would say more matt than glossy

Here is some more pics. Humidity at the mom, they are 3h awake is 45

And what im putting to wather is:
Canna a then canna b
150ml rhizotonic
And last time 80ml calmag.

Here are pics of one that slowed down



And to compare "good" one



Leaf septoria - that what i would think it might be

Here some pics of weird leafs i could find

I can see in the pic the canna part A has npk numbers 6-3-8

what are the numbers on the part B?

how much magnesium and calcium is listed on each part of the A&B

how many mls of each (and all)product are you adding to your reservoir

which calmag product are you using ? is the N2% Mg 1.2% and Ca 3.2%

Canna a

Canna b


So my tank is 350l. Filled with 250l of wather. Usually 450ml canna a i b, 150ml rhizotonic and as i said one ao far 80ml calmag

the pics you provided
part A and part B are the same

did you accidentally give me the same one 2x

so I searched around
I think found your part B
npk 0-3-5 (is that correct?)

I cant find the mico nutes for the product so I can do a full work up with you calcium and magnesium (calmag)

but I am able to work out your npk numbers

for full strength bloom nutes mix

part A 3.5mls per gallon (4liters)
part B 7mls per gallon

for full strength veg nutes mix

part A 6mls per gallon (4liters)
part B 3mls per gallon

first please verify that your part B is indeed 0-3-5

give me the pic of part B so I can see the other elements (calcium and magnesium)
and I can tell you how much calmag to add

and I will post the spread sheet with all the numbers showing what your feeding

for example




please realize... this is incomplete
since I don't know all of whats in part B the calcium magnesium and micros are not accurate
and after I add in the calmag the N will rise in both formulas

but the npk numbers are good (provided your part B is 0-3-5

I just checked. All numbers from both bootles are the same.. one difference on one is A on second is B. Otherwise is all the same
