it started last week feeding fox farm trio and cal mag....any one know what this is?
Mag deficiency?

Over fert. If you want solid answers you got to provide more info. but looks like over fert.

Thanks what info do u need? I feed every time I water but I don’t water heavily I’m gonna cut down and see what happens.

That should be good. Thing is though, I have had times (actually having one now) where I test the soil pH and it's not even close to the pH of the feed. Even after a flush, so if you have a reliable soil pH test kit / meter handy I would give it a test when it's about halfway dry. Just to see if the rootzone is really getting 6.5.
also make sure there is no chance you are getting rootbound. I have no idea how old the plants are.
Are you using tap water or RO water?
Whats your feed PPM?
Have you any reason to believe that you need a flush to get salts out of the media?
Personally I see a little bit of indication that there is a pH issue or perhaps a csalt buildup issue that is causing nutrients to be locked out somewhat. I have had this problem in the past when the media gets a pH fit like I described earlier. I just water at a higher pH to try and drag things towards the 6.5. For example, I tested at say 5.5 so I feed the next feed at 7.5 and then retest the soil and it's moved to 5.9, so one more time and I expect to be close to 6.5.
If you want to flush to get salts out of the media then follow that right after with a feed it won't hurt. When flushing just use tap water or if using RO water add 100 PPM of epsom salt to the mix, flush with twice the volume of the pot and follow that right away with a full strength feed. At least thats what I do lol. It's a good idea to do this every few weeks just to prevent a salt build up. And always water with at least 20 percent runoff. Don't let the plants sit in standing water tho, empty those saucers.
I hope all my rambling helped a little.
Lets see what others have to say too.

Definitely don't feed every time you water, plants likely have too much nutrients and can't handle all of it.
What kind of soil are you in? Because if it's Fox Farm's Ocean Forest then that explains the issue, FFOF is pretty hot already on it's own and is designed to go without any additional nutrients for a good couple months. Back when I used Fox Farm's stuff, I'd mix Fox Farm Happy Frog, Coco Coir, and Perlite in with the Ocean Forest soil. Using FFOF by itself typically resulted in nutrient burn for a few weeks until the plant became more established.

Looks like a salt buildup. Definitely heavy feeding and looks like you are locking out macros, except N because it's almost toxic with it at this point.

leafy, if you have to ask what info to write here, you probably shouldn't be growing. what fert do you use? how much each time? how often do you feed each week? what are your room temps like? what lighting and bulb distance is present? is it a well-balanced fert or just NPK? you have to describe the grow and what you.

So if you don't "water heavily" then your watering a little bit all the time and your medium is always staying wet, also don't feed every time try feed/water/feed/water
I recommend you go to a wet/dry cycle, and on plain watering days collect some of the approximately 20% runoff that you're going to start having and check it for pH and PPM, keep notes and see how it changes from watering to watering, do a slurry test of your soil pH
I agree with consensus that you probably got a lot of salt built up as well and suspect your soil pH is off causing some lockout.
You do need to read more, but that's not an insult we all had to learn. Research adding lime to your soil to buffer pH, also make sure your pH meter is working properly and properly calibrated, good luck

I’m using happy frog with 30 percent perlite I’m going to use just distilled water next time thanks

I know I have to flush but I didn’t think so soon I’ve only been feeding for like 3 weeks I usually flush before flower. I’ll make sure to check the runoff when I water next time. I use happy frog soil with 30 percent perlite I don’t have a way to check ppm i usually just feed half dose and I’m good. I use distilled water btw and I don’t take this as an insult, I’m open to constructive criticism I appreciate the people who take the time to respond. Thank you going to do the wet dry cycle.

I think Kratos is right. I use the same set up with FF products. I water once and next use fert. I alternate between grow big and water during veg and tiger and big bloom during flower. Just give the plants a break between ferts and you should be all right. If the leaves starting looking blotchy I add come cal mag. As far as wispy flowers go you might want to get a more powerful light.

Salt build up causing pH issues.
Feeding every water will lead to build up of certain elements that will lock out others or create pH issues.
That flush of plain water every other or every 3rd watering, flushes out excess salts and helps balance things out when you add your next feed.
That's why nutrient ratios are important.
I also read quite a bit about fox farm soils being hot out of the bag which probably compounded the issue.

Well assuming lighting temps and soil is basic knowledge then I didn’t realize I would have to be that detailed I apologize I’m fairly new to the forums my humidity is between 48 and 53 percent temp in day is between 75 and 79 Fahrenheit at night it’s 70-75 humidity stays the same I’m using 135 real watts cfl and 80 real watt grow led lights I posted earlier what I feed and that I’ve been feeding every week I’m in happy frog soil with 30 percent perlite I’m using fox farm trio and calmag. Growing in a 2x2 tent in closet have a strong fan and I keep my windows open for half of each day my light cycle right now is 19 on 5 off.

You don't need to fert much with happy frog. it has fert already, even if you dilute with perlite. You have dark green leaves with leaf tip death which usually means over fert.
