Possible Heat Stress? Glue Gelato Auto

Unsure what to do. Pics below. Grown in Plant Magic soil, had very light amount of nutrients, PH of water was initially 7.5 when I started the grow but I’ve now given it water 3 days ago which was 6.5 . New leaf growth hasn’t seem to be affected. Plants are still green in colour, no abnormal discolouration or anything. 600W HPS

temps were 29-30C initially, last week I dropped the temps down to 27-28C. This was because I noticed the leaves looked a bit crisp, and so thought I’d just drop temps slightly to avoid it getting worse, but unfortunately it’s not got any better.

none of my other 5 plants have been affected at all in this way - this is the only Glue Gelato Plant, the rest are all Girl Scout Cookies and ALL look very healthy in comparison.

any input from people?

Yup. What your RH? Even the soil looks dry af

humidity inside the tent has ranged between 45 lowest to 55 highest. Currently it’s 51%

edit - I did test the soil about 25 mins ago and it is dry, does need a water but the soil I’m using is renown for holding moisture well. I’m contemplating a water tonight.

Looks like heat stress couple with needing a drink which is exacerbating the heat stress.

The soil is really breathable too so keep it on the moist side rather than bone dry

I’ve been watering it every 3 days ish. Over watering concerns me massively so I’ve been leaving it ages aha
Oops.

don’t forget that the section between the leaf and the soil is like a little biodome of humidity
- keeping this moist helps the plant retain its water while it breathe without losing as much through its perspiration.

If it worries you that much aerate your water for an hour or two. Keep it cold

so just out of interest even now I’ve lowered my heat and given it a water, those leaves will never recover right ? Should I just snip Them off?

Don’t cut them they may look ascetically displeasing but they are still a power house for all needs of the plant. Now if it was necrotizing id snip those bitches
