taco?? is that the same as the claw?? its not too hot i think.about 26 c at day. and 14 at night.but even though only 16 days flowering,They are 9 weeks old.Maybe this is why the big ones are more than 3 feet allready??and btw.How tall will my plants get???Your plants are looking ok for a first grow.
they are looking a little stretched maybe look to get your light a little closer next time or maybe train them using LST or FIM or TOP.
It looks like you are experiencing the TACO effect on some of your leaves. This is usually caused by a couple of things. Nitrogen toxicity and HEat stress.
What are you temps at canopy level???
How strong have you been feeding them and how often have you been feeding?
