Leaves curling inwards on plants - what's going on?

Mid summer here in NZ and we've had a bit of a heat wave (mid 20s - early 30s). Have been watering my babies every evening once the sun sets and have been feeding them Thrive (seaweed/fish blood and bone - last feed a week ago).

Their leaves are starting to curl up on the tops, especially the front row of plants in my plot.

Any idea what could be the issue? Let me know if you need further details.

Thanks!

Got any pics how big is the plant, its either you are feeding too much or overwatering.

Do you know what caused yours to do the same? I was thinking maybe the heat because it has been rather warm here... just want to make sure they’re at their healthiest for their next stage lol

Did you buy your soil from mitre 10 or bunnings? I've had issues in the past when using their soils..Most of them are just too dam hot with nutrients( even their organic soils) .. hyalite stock a soil called terrazilla that most strains do well in..

It could also be heat related as its been rather hot over the last couple of weeks..The humidity has been way too high too.

Alternatively , you could have nitrogen toxicity which looking at your picture looks unlikely. If the problem coincided with the current heat wave then I suspect your issues are heat related..:leaf:

Heat stress for sure. Rub the leaves between your fingers, if they feel dry and rough they are likely too hot.

Water the fuck out of them and spray them with a mister 3+ times a day, hourly if at all possible. Trust me, with heat like that you are going to have zero problems over-watering. In fact, you'll be battling with getting them enough water because the sun is likely drying the water out of your soil before the plants roots can uptake it.

Just give them more water and spray them down often and you'll be fine.

Too much fertilizer...killing them with kindness. A common mistake. Sometimes it is hard to tell how much as different strains can tolerate different amounts.

Heat stress or russets will do that. If it’s russets hit them wit wettable sulphur ( just don’t use anything oil based AND sulphuric, one or the other)
You’ll see a 30X or strong glass to see them. Little torpedo shaped buggers!
You don’t want russets nights in flower!!

Hey bud I'd say it's the heat, gotta be careful of how much seasol you use to it can cause a change in pH due to how concentrated it is.... If Your feeding on the reg but you have no sign of burnt tips so I'd say it's heat stress, best of luck bro
