Leaves folding down

Flushing water was ph 6,7

Water until run off only correctly ph'd water check the ph of the run off often when you have more than one deficiency it's because the ph is off at roots causing lock out If your pH is out of range flush her through with correctly pH water good luck with the rest of your grow 🌱 🙏

Looks like you may have a few issues there nitrogen Toxicity maybe a nutrient lockout of some sort depending on how long you have left I’d start flushing but it’s hard to tell without any info buddy

What can I say you more?

If putting up a diary is too much like a job, then perhaps you don't need our help? You're overwatering or giving too much nitrogen or lights are too close or you've got bugs. Take your pick and good luck.

Looks like heat stress or over watering. If your letting your medium dry up a little inbetween watering then it won't be over watering.
