Something is wrong with the leaves, can somebody tell me what that is?

I post few pics of my plant, one of'em was taken 3 days ago and it was perfectly healthy. then I went out town for a day, when I got back, the leaves were already sagging like this, and there are countless yellowish gray little dots all over the leaves.
Anyone knows what happened? Please let me know how to cure it.

Could be bugs...check with a scope or mag.glass top and under leaf too!

ye I thought of that, I checked the back of leaves and the stem, but they seem okay. could that be something else? or I'll check it with a scope later

Check on the top of the leaf...look for any one of those whitish grey things to move, thrips are very tiny got to have good eyes to see them.

I did find several aphides and wiped'em off, interestingly, they weren't running away, they were probably just on weed...lol, but I dont think that amont of aphides could have done this much damage, so I raised the light a bit further and stopped feeding fertilizer.
Whatever the problem was, thank u for helping bro!!

ya you have multi issues here. pH is out form the leaf look and then it looks like mite damage as well. we only get bugs usualy when the plant is unhealthy. they cant attack a healthy plant. they have their own deffence against this.
what pH for food and waters. and what is the run off pH ned ec

thois funky colours on the ribs of leaf in pic 3 is pH. the spots are bugs

hey medi~thank u for guiding man! Unfortunately this is my virgin generation (actullay I tried once prior to this, but seedlings died shortly after germination), so totally 0 experience. I'll get a pH tester ASAP. What are the pHs should be, both feed in and run off?

I saw this in another grow. It was fungus gnats in the soil. And the spots came from the gnats attacking the leaf when the soil was too dry for them to survive. Where do you keep them? Noticed any flying critters?

The spots could also be mites...but its a critter of some kind or another.

need to know the type or brand of medium to know pH. like soiless or soil. 2 diff pH needs.

what's ur pH tester? or u got recommendation for me?

well i have acess to top of the line stuff. so im using a Blue Labs Gaurdian Tri meter. reads it all. pH, ec, cf, ppm, and tds. and temps. so if ya want to drop about 400 to 500 on this unit its the bomb. i laso used a pen for a about a year that cost me about 80 bucks. was ok. did the job.
all comes down to what you can afford to drop. dont cheep on tools or room. with out this nothing will run right,.

ok, so how about these, both for soil and water, do u think they can do the job or I just cant trust their qualities?

dont waste time on the first type. no need for diff types for testing foods and soil...same pens. and those probe ones are real sad. only tests around the probe. need the whole medium. and dont go jaming on all over the soil and bust roots to get an average of whole medium. i cant say on the milwakkee as ive never used one of those. they all seem to be a hit n miss on if they work well or not. spome may work good and stay calbrated and some may not. all pens are like this. so its basicaly buy one and try it. if not send it back. betetr to be able to walk into a grow store and buy in person for this reason.
this is what i was using for the past year till i got this tri meter.....

this is the same but no temp adjustment.....

this is the new one i use now.....

i also tried this one for a week or so. was having issues with the ppm readings not matching but then i had issues on the first blue lab and sent it back and this one is fine,

also that link to the shop is my shop. we give 15% off on equipment medical if anyone is, and 20% ion foods or liquids.

by the way, I checked the link to Pre-98 Bubba Kush and Tora Bora With Medi-One 1 Part Nutrients, they look sooooo minty!!! I saw some of them are pretty short which probably just weeks old, but how did u grow'em so strong, I mean the stems look so thick!! as u can c through my pics, my plant might be taller than ur plant, but the stem is no more than a spaghetti......

ya they beginning got messed up for what ill be using. so far no foods have even been used. still running on what the soil has in it, then ill begin the medi one. all are tora bora and are 99% indica. i have the 1 pre 98 bubba in it but still healing it

and i run a few you tube channels if you wanted to follow along. ill be leaving this site soon as they force us to re confirm as im not interetsed in being told i must register for a newsletter with a 3rd party. so once this happens ill be gone from here as we are beuing booted if we dont sign the dotted line. i dont do the "tell me what to do stuff"....lol

I heard that some say swing ur plants with a fan 24/7 can help the stem grow thicker, it that ture, or there are some way else

FWIW, I have always used just the 5.00 pH drops. If you use the same water source, the pH of the water wont change. Once you test your nutrient mix a couple of times you will see that it doesnt change much either. As for testing your soil, thats easily done with pH drops as well. PPM and other indications are more important in hydro systems. Soil is more forgiving.

I'm not saying you dont have pH problems, as you probably do if you havent ever checked it. But pH problems only become apparent when you have signs of nutrient problems, as an "out of limits" pH prevents the uptake of nutrients, or nutrient lock.

You can spend alot of money of tools if you like. Some people just like gadgets. And some people just think you have to by all sorts of stuff to get a plant to grow, whilst others are trying to sell you the "this is what you need" item that is going to make them money.

Or.... you can get the drops, establish what your "normal levels" are. Adjust with some pH Up or pH Down if needed, then let the plants tell you if there is a problem. In my experience, once you know the pH levels for the water, nutrient mix, and soil, its just a matter of adjusting up or down everytime. Unless you are adding things you normally wouldnt, your pH levels for water and nutrient mix wont change.

The soil pH can change over time as the nutrients in the soil are used and salts build up etc. In my experience I check the pH level of the water run off in three stages:
Mid-Veg (approx. 3-4 weeks)
Flowering Stage
Start and End of Final Flush

In my soil grows I find that my pH levels only changed at those times. The levels would drop slightly, and so I stop using pH down, once flowering starts. My water pH is high so by not using the pH down that I use during veg, it bring the soil pH back up.

The point is, you can spend the money if you feel you have to, but drops will works just as well. Scientific rated tools are used where accuracy is critical. Any plant you grow wont need that level of precision. My 2 cents

swing them???...hu...like take em to the park and go on the swing set????...lol. yes having a fan blow on them gently will help thicken stems. and needs it to move air around room mainly
