Yellowing on GT and clawing on CB

You have leaves tips that are dried and it's can be because of the high temps or because of some over feeding but your temps are goods ( day & night ) & when I take a look at the dark green colour of your leaves it makes me think about a Nitrogen excess / Nitogen abundance so a Nitogen ecxess can create a nutrients lockout and then create an early senescence ( se,escence is a natural phenomenon , in the late flowering the cannabis plants are tending to loose their colours and get slowly yellow before harvest ). The clawing on the leaves combined with the dark green colours is clearly showing a nitrogen excess as the clawing is a well known sign that appears when the nitrogen amount is too high . Generally to reduce the N amount in the soil you can flush your medium with fresh water to "reboot" your soil , for exemple if your pot is a 10L one then you can add 5L to flush ( lil flush ) or 10L ( big flush ) , or you can change your watering routine by stopping the nutrients during 2 or 3 watering to let the plant use the nutrients already available ( but a salt build up is better fixed with a flush ) I am inviting you to type those words in google : "cannabis nitrogen excess signs" , "cannabis leaves clawing" ; "how to fix cannabis nitrogen excess" You can also check the PH of the soil or of the water runnof but I can't clearly observ ant ph issue signs on your plants
