we need more info mate, and whole plant pics,... please fill out the patient info form that's in the colored section above this one; just read the needed info specifics, then c/p the blank into here- :thumbsup: .... these are the details we need to diagnose this properly,....
Might be the in-pot pH is off, and/or you're running low on certain nutes,... Or there's something off environmentally, causing a VPD issue (vapor pressure deficit).... Very important thing that, the Reference section has a good article on this! So much of the performance of a plant rests on this careful balance of T, RH% air movement, etc,....
--- light distance and type needed....
 
All such recommendations are general, strain specifics and other conditions can play their roles too for light blasting tolerance,... If the problem is appearing mostly on the tops, that's a tell right there, along with the mild distortions of the leaves,....
VPD is borderline, and combined with potentially too strong lighting, it can trigger such symptoms.... hiccups like you had can tip things over the edge too,... P and Fe are really badly affected by cool T's....
pH is OK, on the high end of optimal range,.... SoHum is right about occasional light supplementing with nutes, especially during bloom,... KIS, Biotabs, KindSoil say similar things,.... I had to feed extra with both KindSoil and Biotabs, the plants simply used some things up by blooming!
Let's see if the feeds help,.... :thumbsup:
