Leaves curling down, getting yellow from outer part of leaves inward

Yeah i would agree with these guys. I know it looks like your late veg 11 weeks in but aren't those fox farm nutes pretty strong? Calibrate your ph pen too , i got some twisty knarly leaves beacuse of fluctuation with my cheap ph pen. Wont happen again . Also yellowing from the outside in on lower growth definitely looks like a deficiency. Also i see terpinator in use ... isnt it a little early for that ? I see no calmag in there either . Ppm's you been putting in plant would help too. Id suggest 750 to 1000 in late veg, im also not familiar with fox farm nutes or hashplant genetics. Hopefully helps a little

Looking at your feed, and the overall health of your plant. It's most likely a slight excess in pk and /or a slight nitrogen defeciency. Try balancing your grow and bloom nutes. Make sure ph is at 6 - 6.5👍🌱

Nitrogen Tox.. To much Nutes.. Flush her out .. only use water the next two times then give a lower dose of your nutrients.. Hope this helps! Happy growing.. 👊

curling down is usually toxicity of some sort. Ease up a bit. You know your recent behaviour in this regard better than me, so easy to eliminate if wrong. always easier to dial back first, then add later.
