This is my 6 weeks old royal cookies autoflower. It’s been growing great but today I see that the leaves are “tacoing” a bit and the new top leaves have a lighter colour. I grow in soil mixed with perlite and grow under a marshydro ts1000. Light schedule 20/4 indoor. It’s been 2 days since I watered and the soil is now really dry. I heard it’s not always a bad thing to let the soil dry out a bit before watering. I hope watering will fix this but I wanted to make sure there’s not another problem. Any help is highly appreciated! Thanks

Go hit Google for "VPD scale cannabis" and do a bit of reading bud. Half hours worth and you'll know all about it. Vapor Pressure Deficit. It's basically about how temps and rh work together with the plant. Would take me a fair while to explain it properly but go have a read and I'll be happy to answer any questions
