so ive been on the faqs and i still cant seem to find what is wrong with them .
the leaves start yellowing then they turn brown and they get really crusty.

They are all outdoor.
About a month and 2 weeks old.
Using Fox Farm Trio and superthrive.

I have used vinegar to bring the PH down because
the soil PH was at 8.

Haven't tested PH run-off. Meter broke.

Live in SoCal. Hot and dry.

well, if the soil ph was really 8, that's not good, really alkaline soil
plant certainly looks like it has been suffering from ph issues
you can get ph drops/strips for $5 - you really need to be able to measure what's going on with the ph

Hey,
well I am just guessing but bring your pH down around 6.4 and dont put vinigar right into your soil. Get some pH down and than adjust water... Superthrive is like a steriod for plants so maybe give them some water since plants will use more (H), (O) than any other elments that can be found in micro and macro nuts.

K good shit, just remember it does take some time to lower your pH... Your soil does act as a buffer so it may take a few times.. That is why I also feel you should water good but less so u can water often!!
Hope that works out for ya!!! remeber 6.4 is IDeal

from the looks of it, you also have dry weather issues, which means you need give your plants more water, to check and see how much water is in your pot, after watering, lift the pot and check the weight, if its heavier than regular then you dont need to water them, if the pot feels light and the soil looks real dry then you will need to water according to how often your pots go dry, when plant does not get sufficient water, the tree sucks the water from the leaves leaving them dry and shirbbled.

Fox Farm isn't hot, I go full strength on mine, they can't get enough, superthrive on the other hand I have no knowledge of, but don't listen to dickweed. lol name is appropriate. IMO looks a bit heat stressed, is anything chewing on it? Any bugs on the leaves?

Oh those leaves show signs of heat stress!!!! Those plants should get a little shade until they loosen up lol.

I second this. Looks like a case of "hot and dry" to me, for sure. I know everyone is quick to say it's the pH, or nutrient burn, or whatever... Honestly, cannabis is a VERY hardy plant (easier to grow than tomatoes, at least in my experience). Maybe a magnesium uptake issue, which can be solved by adding a quarter teaspoon of epsom salts to a gallon of water and applying it to the soil around the plant.

and plus rep to everyone who helped.!

and as for the nute burn im sure its not that
been ussing a ppm meter and the doses im giving are pretty low

My 2 cents is magnesium deficiency, probably caused by your pH. Doesn't look like nute burn at all. The epsom salts will solve it, but the damaged leaves will remain damaged. Doesn't look too bad though.

last thoughts, it is quite possible to have more than 1 problem, which usually makes diagnosis the bitch that it is
he claimed he had a 8.0 ph soil in the beginning of this post, that is not a good ph
couple in heat/water issues, and symptoms of ph will likely get worse
