Pale Light Green Spots

[Griszo]

Hi everyone!
Growing médium PeatMoss, Perlite and some humus. Transplanted 1 week ago to a bigger container. Now some New growth are showing kind If deficiency. 4 of 8 plants are with the same problem. Using Top Crop Nutrients.
Please, what could It be?
PH Water controlled btw 6-6.5

ph is always first. i think you levels are a bit low. a good all around ph like 6.8 is nice as it's the best range to absorb nutes... in general as there are strains that need lower ph for say like iron uptake. i assume you are using a calmag suppliment? you're doing some next level training so i assume yo know everything i'm saying here. if you ph is too low, your leaves will show deficiency. raise ph and spray a diluted calmag on both sides of the affecte leaves, imho. recommended is 6.3-7.3 and i think 6.3 is low, but others have great results. research the strain and see what it favors and adjust to there. it's more of a formula instead of a science. good luck.

If you are in more of a soilless medium, follow the scale for hydro.
My input pH is 6.2-6.5 in soil and ride the drift upwards.

Yes, I understand! I use a CalMag direct in Soil as Poder Fertilizer, not as Liquid fertilizer... Where I live is a bit hard to find CalMag Solution for Cannabis. At First I tought It Could be CalMag.. but the demage pattern is not similar. I Will raise the pH to 6.5-6.8 next watering and try to find some foliar CalMag fert. Im Just a bit concerned cause I never had this issue... Thank you Very much!

So you Think I should even try even lower pH? What nute def/Lock out is going on? What you Think? Thank you!

Here are a couple more helpful charts. I would not pH above 6.5, as a matter of fact, your medium seems more like coco coir, which you would want 5.5-6.0.

If your at 6-6.5, but your medium is more like a soiless medium, you’re locking out Manganese and iron it seems to me.

Are you using a pH pen, or the liquid testers?

pH pen, good one.

hey... i’m not perfect, so i’m gospel. growweedeasy.com most likely has a leaf chart. i know for me, as soon as i feed my plant 2.5-5ml/gal, my leaf symptoms vanished. i still get spots... but a good base nute can be killer too, like biobloom. in the pic is what i first went with and worked great. i use the cal/mg+ now which is more expensive but better and organic. about 20 on amazon. So, amazon is all you need. are you afraid of what’s in the mail?

thanks a nice chart i’m sure to keep, along with the others i have. it’s really all about runoff.

Depending on who you speak to...

Gave them some foliar Fertilizer today, still bit light Green spots

 

[AdaminCO]

Those most likely will never correct theirselves. Look at the new growth only.

Unfortunately where I live there is no Amazon shipping overseas to Southn america

 

[Griszo]

Should I water with only water next time? Which Fertilizer you recommend? Thanks

How are you watering? From the looks of it you might want to read @Emilya watering “guide” in my signature. Looking dry on the edges.

I grow in organics so I make my own compost teas. First grow so I'm learning too... just don’t have the worries most do.
Unless I tweak the recipe and mess up a batch (guilty), I don’t worry about overfeeding/ferting.

Hey gostaria, Gave them some pH Vegetative nutes with a bit lower pH (6.0). They are doing fine! Gonna make some TOPPING tomorrow! Thank you for the answers, graphics and attention!
