Problem with the leaves...please advice

Hi guys,

I'm giving a try to a Power plant, she's in the 5th week of flowering now, just started her on nutrients 1.5 weeks ago (gave it 3 waterings with nutrients)
Soil grow - plargon royal mix and nutrients from plargon - algae juice( all organic); still water - ph 6.5.
The leaves are twisting and curling.
Temp 24-26 C and humidity ~ 45-50%;
Please advice.
The second one is doing a bit better, she's a California Hash, a bit small, but looks well, only thing the tips are curling down (same setup for her as well)

Leaves usually do this during late flowering, or it could be nute burn. Since you only just started using nutes then you should only use them like once a week.

and some pics with the california hush

I am just respecting the instruction from the nutrient and soil. If growing in plargon royal mix, you are supposed to start nutrients( algae juice from plargon) only in week 4 of flowering and give constant 20 mls per 5L of water. Don't think it's nutrient burn nor late flowering. pH is in good ranges...

"just started her on nutrients 1.5 weeks ago (gave it 3 waterings with nutrients)" 10 days and 3 feedings? no straight water in between? Plant is in shock Im betting...flush it and ease back on the nutes again. ease back on em ease my friend

Ok, I'll do that, will see how it goes

the leaves might turn or twist upside down due to closure to the light bulb ? like heat stress? anyway, I'll give it a good water and try to reduce the nutrients to once a week or at least one with and one without.
