Leaves turning brown and curling upwards like taco

Hello GWE community im having problems with my girls and i need ur help to diagnose it.https://ibb.co/jCWKek

Ph went up to 7.5 few days ago i've tried vinegar and lemon acid to make soil more acidic but it seems to work only for like 6-7hrs could that be the main problem ? Ive been using biobizz bio grow bio bloom and top max also used home made calmag but it still doesnt help. Plant is already 3 weeks into flowering. Strains is cholate haze special queen1 royal medic all from royalqueenseds. Btw theres is no ph- supplements i can buy anywhere near me. Water ive been using had ph 7. Can it be heat stress ? Im using 600w hps with 0.8 0.8 120 grow tent extraction fan and one additional fan at the bottoms of plants. Near bulb its arround 40° celsius but at the bottom of tent it says 25-26. Sorry for bad english guys and looking foward to hear from you

Try to balance the Ph of your water with lemon juice to about 6.5 give it to your plant until you have enough runoff to measure (vinigar contains alcohol and i keep that away from my plants and from myself!).
Put that runoff true a sieve to filter out perlite and other stuff and measure it but wait 2 min. If your ph is still to high i think its best to give your plant only PH water balanced to 6.5 until you see it in the run off. i don't mean flush it but give water wait a day or 2 and give back water and every time you do that make sure you have enough runoff to measure .Your already in flowering so flushing gives to much stress so i would not feed them with nutrients, just PH'ed water until your Ph is right! when you Ph is that high your plant won't take up any nutrients it wil only toxify your soil more cause there are no nutrients going to the plant so you might end up with more problems. For the heat you should feel with your hands above the canopy , if your hands hurt after a few minutes your plants wil feel the same. I can see that your leaves are curled up, so i think they might get it to hot... i would put the light up for a few days to see what they are doing and look for recovery by checking them every day. i think your plants might have nutrient deficiency caused by the ph that is to alkaline or they have to much stress caused by to much heat, or both . Tell me if i'm wrong , i'm stil learning everyday! do you have equipment to measure EC ?

(+ i've checked the strain and the chocolate haze is one that is not that easy to grow... It's more a strain for advanced growers say's the website... )

Sorry for my english two

Thanks for your help,just flushed plants with water phed to 6 And runoff says 6.5 used 1ml/l calmag and 1ml/ biobizz bloom and top max they started 4th week flowering 07/28 i can`t move lamp up anymore so i`ve placed additional fan at the top of plants i hope they'll get better. Thats my first grow so i would be sooo sad to lose em now... btw my soil ph tester still says soil is 7.5-8 ph how can it be?

I'm only on my first grow and your problem is not something I've dealt with myself so my answer may not be the right one BUT I believe you want to water/flush with more acidic pH (like, under 5) until your soil pH gets down in the 6s, then switch to correctly pH'd water. Either that or really flush it repeatedly with water around 6 (until the soil pH goes down) but I don't know how great an idea that is for soil (vs coco which would dry out much more quickly). From the pictures it does look like it could be heat-related, too. Good luck, I really hope things work out!

Depends on the quality of your measurement tools maybe, i don't know if you work with ph meter of a good brand...
The hight of the lamp is a bigger problem and i don't think an extra fan wil help against the deep penetration of the lightning waves trough the leaves :s I would put them immediately under a lot of TL light's to save them if possible and look for a bigger space ...
I know the harvest wil probably be a bit poor but if you want to save them (if it's not to late already) you beter consider to handel the heat problem because it's devastating for them
How much distance is between the highest part of your plant and the lightbulb?

Don't judge yourself for doing wrong things man... everything is hard in the beginning... i'm also learning to grow two but i would recommend to read a LOT about growing
and thing twice before taking action. Checking space you have, witch light suites best for that grow space etc...
Also the strain you grow, there are strains who are very easy to grow (i'm growing myself a beginner strain Purple bud from white label)
Believe me, i did a lot of things wrong with them but they are very strong plants so they can handel some mistakes.
Anyway i hope you can save them!! Good luck and let me know if it worked!
