Leaves distorted and pale colour on some leaves.

Hi everyone! First post here , sorry it's asking for help!

I have 8 little ladies (4 in 15ltr pots , 4 in 7.5ltr pots)

Strain: LSD_25 auto from fast buds

I'll start with my feed (this is to 10 litres of water)
10ml canna a
10ml canna b
30-40ml canna rhizotonic
4-5 drops of superthrive

I have a 4x4 grow tent with two 600w viparspectra LED lights.

Can't find an exact match to what this looks like so don;t want to misdiagnose.
Anyway basically my leaves have been becoming slightly distorted and some are becoming pale on some of the older growth but not the whole leaf , and they are only seedlings. to me even though this is my first grow they have all looked a bit pale for my liking, but could possibly be to the strain? any help would be appreciated thank you! x

Sorry forgot to post some info;

Growing medium is canna coco pro+

PH for feed is around the 6.0 mark.

I would get some perlite in there.

Could be PH fluctuations or not enough nutes.

you dont need perlite
and you do NEED to let the PH fluctuate (5.8-6.3) or you will lock out nutes

looks more like enviroment to me, temps RH, i would leave out the superthrive untill it sorts itself out, everything it needs is in the A/B



heres a chart for ph, some new growers keep there ph at 5.5 some at 6.5, you can see how they lock out certain nutes by not varying it

People start in straight coco all the time.
Could be temp (swings).
I don't use canna products but in straight coco you have to provide CalMag.
So if that's not in the nute blend, get some.
Bennies (bacteria) should be in there too. If not, Recharge is a great way to introduce some.
And sometimes leaves just do weird shit.
Unless this continues to occur or get worse, I'd say less is more at this stage.

i always thought the use of cal/mag was dependant on your waters EC, also canna A/B has cal/mag included, dont give them cal/mag unless they need it, get yourself an EC truncheon and feed them at 1.2EC, with the ratio your feeding at the moment you would be getting around 0.8 -0.9 EC, use 1.25ml - 1.5ml a litre
as for bennies wouldnt the canna nitrate based fertilizer kill um ?

See, I don't know Canna products that's why I mentioned it.
If it's got everything, then he's good nute wise.
It doesn't look like anything I'd be too worried about.
Won't be the last curled leaf that plant puts out.

Hi guys thanks for the input, I'm probably just gunna put it down to the strain. they did look very pale and weak when they germinated so could just be bad genetics. keeping my PH between 5.8 - 6.2 and just a 1/4 strength nutrient solution

Added a couple of new photo's of the girls , they are growing fairly well (not too sure as it's my first grow) so think i'll just let them ride. I will keep cal/mag at the back of my mind though as i'm unsure on how much is in my tap water , need to check that out , but i do live in a hard water area.

Heres a couple of Pictures, the first couple are of my better looking girl, and the weird growing one is last.

(and upped the nutes from 1ml a litre to 1.5ml a litre)

gazza get yourself an EC truncheon it will take all the guess work out of your fertilizer strength

It's next on my list, Just a bit skint at the moment until my first crop comes through, the setup cost me a fair bit

Can anyone recommend a good EC reader that's cheap? that bluelab one it like £80
