Is it normal for my fan leaves to turn yellow while my pistols are still white the other plants are green with amber pistils

@BluntZilla it’s a 480 watt from a amazon seller cost 380$ and the driver isn’t even in the tent cuz it wasn’t attached and it gets hot and it comes with a dimmer and a decent amount of wire so I’m able to rest it on a ceiling lamp dome on a plastic tote so it don’t melt any plastic or catch any wood on fire luckily I thought to search if they get hot I was going to rest on top of my tent which is a 4x4 the reason it gets so hot when the tent is closed I wasn’t able to open the tent when the light went on at 6pm and thanks for the tip about trying to vent it better I’m gonna hook my online fan up with dryer ducting out in the living room where it’s cool and put the carbon filter and fan outside the tent in the grow room or something so it draws cool air from my living room into I usually open the flaps of my 5x5 and my 4x4 cuz my dehumidifier is in the 5x5 also the 5x5 has been real humid due to flushing and the 4x4 has been good

The temperature fluctuation might really be the case, you really don't want to go over 30 degrees Celsius. If you're using a LED board with Samsung diodes then the heat coming from the lamp shouldn't be that bad, in any case try connecting your intake fan/opening to outside for cooler air coming in or if you can afford it get an a/c working in there (there are more options to cool off your grow space just need to get creative with it). Just to make sure check your pH and if the yellowing is more severe at the bottom of the plant then increase your PK fertilizing, and if the yellowing is more severe at the top of the plant then increase your micro and trace nutrient fertilizing (focusing on Cal-Mag). Hope this helps! Good luck and happy growing :)

I’m sure it’s the temp swings it’s been crazy in central Florida lately it’s normally easy to control 70-85 during the day 60-70 at night during the fall and winter i just changed my blurple pos to a 480 watt Lm301B so it’s been crazy last 24 hours it’s a low of 70 and a high of 100f cuz I worked today late so my tent was closed with the light cranking but in the last week it’s been a high of 100 and a low of 62 and that’s probably the cause but not effecting the Ebony & Ivory plants or the Bubba Kush just the 2 bag seed allegedly Sherbert that don’t look indica p.s. how I lost pics of leaves

Could be so many things. Nutes,temperature,humidity or a combo of all. Leaves turning yellow and falling off though are not normal post some pics of the offending leaves and also what nutes you use and what kind of schedule you are on. Lights? Height of light room temperature all these are needed for people to be able to give an accurate diagnosis. Good luck.👍

Leaves turning yellow and falling off is never normal not even during flowering!! a few pictures, and info about the setup and nutrients would help determining what is the problem.
