so i got my plants under 250W metal halide about 12in away from all of them i got a 9in oscillating fan blowing at them. the temp ranges from around 23-29 with the lights on ..
but the bottom fan leaves on all my plants are droppy and yellow some have brown crispy spots on them ?

the soil is 50/50 perlite/soil for acid plants like . 'azeuleas':???: ?

last week was pritty hot so might have been heat stress?
i just repoted them into bigger pots as the were pritty much rootbound.
ive been watering them with tap water left out for 24hs..
but i just recived my ph down so now being watered at the correct Ph..
i cant figure out why they look so bad. not looking healthy at all ..
any body know what im doing wrong? need help

You have a bad bad case of nute burn bro. Flush these out ASAP. Your soil is also retaining too much water or salt from the nutes so make sure it drains well. Flush them out with only water make sure most of the water drains then get a fan on them to dry them out. You have about a day before its too late for this girl

Try flushing with distilled water 2-3 times the size of the pot.Then let them dry out.
Was the soil soaking wet?How hot was it?

ontop of the nute burn, take those rocks off of the soil. The roots nee to be able to breathe as much as possible. Plus mold can grow under them.

I buy plastic 7 gallon grow bags, and after i fill them with dirt, i go freddy crouger on their asses with a pair of scissors. I poke holes every inch on the entire bags.

Ill take a few pics of my rootballs after this grow to show you how redicuously thick and juicy they are.

i think i found my problem i was using encriptious soil for acidic plants thats around 5-6Ph i think , which i believe is a bit too low . so it didnt show for the first week but now has effected my plants greatly just moved them into mulit compost soil/perlite... hopfully they will look better if a couple days , what you reckon i should do with the dead leaves? cut them off or leave them to drop off

you should really try an organic soil. most of the soils you buy and lowes, home depot or garden supplys contain synthetic time release capsuls of nutes. when they get wet they break open and release. I wouls suggest giving your plants a really good flush of plain ol water, remove the rocks and hope for the best.

reckon i should just get some organic mulitpurpose soil ? and repot them into that . does it have to be organic or is that just to prevent me watering to much and eventually ending up in nute burn ?

How did your plants fair after the flush? You don't have anymore posts so I'm guessing it didn't go well. I hope I'm wrong and your getting ready for harvest soon.

Know it's been a while with this post, but for another time i thought i would give my opinion on this. I definitely don't think this is nuteburn. This is caused by micro nute lockout - that again is caused by the way too acidic soil you used. To fix a problem like this - buy new dirt and get all the acidic soil off the roots - replant.
Do that next time and plants will be happy within a week or so. Roots will be brown and unhealthy, so plant need to build up new white roots again.

Thats completley normal the first two leaves that pop up always die off. At the end of flowering your leaves will turn yellow and may die also this is also normal due to the leaves providing nutrients to the bud
