These are some of the signs i'm noticing...front and back of the same damaged leaf

overall fotos of the most significant damage... on both plants...

this is it, i have not seen bugs or spider mites or anything else temp and RH is under controll and there is enough airflow...
i stressed them in early life with low ph water and later underfeeding since i upped the feeding and watered every day with 600ppm nute solution they seem healthier than before but these problems are getting me a little nervous, i just want to act quickly in case i have a bug/infestation problem.
thank u all.

anytime you see small holes you got to think bugs.

my first thought was you have the start of a cal-mag deficient, which still may be but the case.....but the holes make me believe you have a bug issue

thank u man... but any idea of what it may be...
i don't know how to act if i do not diagnose it properly...
i did thought about cal-mag def... but i'm using tap water with 280ppm and a good amount of calcium plus i fed and foliar sprayed mineral magic several times and it got a good amount of magnesium so i suppose Bloody Bugs...
i just don't know what kind...

I'm happy to say I've never had a bug issue so I completely lack any first hand knowledge....and hope to keep it that way :)

With the chunks of leaf missing, this has to be some sort of bug or critter having its way with your girls...and it will only get worst

you first will need to identified the infiltrators.... then select a strategy to eliminate the bastards

Thanks ISK... i'm happy for you lacking this kind of experience and i too hate the fact that some little monsters are chewing on my babies... i'm currently studying to learn what it can be...

use a magnifying glass to see better, as some bugs are tiny

also, you may consider using some cal-mag as I think this could be a secondary issue

do you have a pocket microscope? radio shack has them cheap 15 bucks. mites will be almost impossible to see without magnification of some type. i had them a while ago when i was buying clones from dispensaries.

pick up some neem oil. it's all natural. mix with a bit of dish soap and water and spray liberally if you do have critters. fogging the whole room with bug killer wouldn't be a bad idea too(remove plants first of course) if critters are present.

either one will be needed when the plants are almost done to see the trichomes go from clear to cloudy to amber so it's def a good purchase.

Based on picture 6, I would treat your plant for Eriophyid mites. Get an insecticidal soap and treat the plant based on the recommendation on the bottle (usually every 2-3 days) and see if that clears it up.

i'm thinking to go this way... i just want to try to identify the problem as best as i can before.
thank u .

An old grower told me if i ever get pests use some neem oil. But I've never had pests. so Idk maybe give it a go. Someone else chime in if im wrong plz!

stop spraying your plant so regular, I recon you are over doing it, this I believe is causing your leaf trouble. If you have to spray do it on the last few minutes of lights on. Them spray drips magnify the light enough to cause damage on your leaf, think fire
starting with a magnifying glass. You have the start of deficiency, this has come from incorrect ph and too low ppm (is that @.5 or .7)
Keep an eye on your ph meter keep it washed and calibrated, then store the probe in storage solution. Raise your ppm up a little, lower your watering frequency whilst they are young. Stop your foliar spraying. I think this will help.

Thanks Reddan.
it all makes sense in your advice and i surely will follow it.
i paused the foliar spray for some 7 days until yeasterday when i foliar fed them again with some mineralmagic.
i'll wait more for the next one. and will do it when lights are just about to go down, in those 7 days i did not foliarsprayed the little leaf holes developed anyway :confused:... some in the lower leaf section that made me think of a bug/infestation problem...but i still don't see anything with naked eye.
it's true i was underfeeding...my meter is Cal @.5 and i did calibrated it and plan to do it regularly ...my tap water comes around 7.5ph and my ph meter when was off calibraton was measuring it @8.5 so i fed in that period @4.7 (thinking it was 5.7):wall:...i calibrated it and for now it is good. if my meter reads another value of my tap water (like it did)it means it needs calibration also i'm double checking the nutrient solution just in case with GH liquid ph tester...i noticed that my runoff these days i fed @ 600ppm was always 270-280ppm so i am sure i was underfeedeing. also i was getting a lot of runoff because i was feeding them a lot thinking to supplement some more food in that coco... by the way for the last 3 days i fed every day to get them some food and they reacted positively with new growth and they lost a little of that yellowing and are now much more greener...these are them after i sprayed them yeasterday...DSC_1303.jpg DSC_1304.jpg

looking better G, stay on point remember the leaves that are damaged will eventually die off, I personally would over the next week or so pinch the damaged leaves off.

Thanks man, but the majority of the leaves got damage ...i don't want to pinch all of them off... the plant will remain with no leaves...
do you think this is not some kind of bug???i still don't see anything. it may be some sign of stress that produces this kind of necrosis or cal.mag defficiency? let's see...
i'll constantly monitor them for signs anyway.
