Im not familiar with your light. 24 and above up to 30 is a normal figure. You have to validate it is light, the pictures you posted does not tell the whole story. But you light is too close to start with.

How much of the nutrients are you mixing per gallon, how many gallons/how often are you feeding, and are you adjusting the ph after adding nutrients?
Not sure the exact cause, but Tiger Bloom is really acidic, I’m using it myself and have to add a good amount of Ph Up to get back in range

12-18” also sounds about right to me for being in flower, but let someone else confirm that-I don’t want to give inaccurate advice

I'm following what tiger bloom says and I'm giving it 5 ml of calmag when it shows calmag def, so tiger bloom is 10ml per gallon, and I feed about every 4 days and yes I do check ppm and pH of mix. I have to use between 2 and 3 ml of pH up to get it at 6.5

I raised my lights the most that I could, the plants are half the height of my grow tent, rn they're about 18 inches away from it, I also checked the roots and the bottom half look like this

What kind of water do you use, tap? If you’re using tap you can probably ditch the calmag. I’m using the Tiger Bloom in a mix of FFOF & FFHF and I’ve only been giving 5ml of TB per gal-I was using the recommended 10ml per gal but it was too much so I backed off.
Do you get decent runoff when you water?
No idea what the situation with the roots are, but maybe it a a build up that isn’t getting properly flushed out

To much nitrogen
Not only are you adding it in fertilizer you are adding more with Calmag
18 inches on light should be fine
But those leaves won’t recover

Im using distilled water, I'm trying to remember what I've been doing more of and I think it's I've been feeding it a whole gallon of mixed nutes instead of a half, they were doing fine until a week ago.

Tiger Bloom is a bloom enhancer not necessarily a bloom nutrient. It should be used in addition to a basic bloom nutrients during the middle of flower only.

Get some fox farm bloom and use that for regular waterings and save the tiger Bloom for week 3-6 as an additive.

For now flush that plant out real good with ph'd plain water. Then water back with 1/4 strength bloom.

I've been in trouble with tiger bloom before.. Following there directions. PH, salts, lockout, whatever. Back way down. check your PH going in with nutes in the water you might be surprised.

I think I feed a good sized dose of calmag only maybe every 3 weeks.

my plants are inches from the light and doing fine btw. Lots of variables go in to how close they can get. Whats your humidity by chance?

I was having rh in the morning of 34 then at night 70, I had to buy a dehumidifier to keep it steady so right now it's between 40-60

I'm also only using tiger bloom, should I use the other 2 nutrients or no?

If you were dropping in water at 6.5 and getting 5.0 run off that sounds like lots of nutes built up in the soil. i bet the ec of that run of is like 4-5 at least. do you check EC/ppm before or after?

I checked the ppm too it's been coming out between 1200-1500 I am going to let it dry out more before I water again so I'll check the pH and ppm again in about 3 days

If you are feeding every 4 days - you overnuted the damn thing. Also , what gives about distilled water ?

Run tap - not only will soil work to buffer it / municipal ( city ) water has calcium and magnesium already in it. So by trying to replace it because you are using “ special “ water is unnecessary. Tiger Bloom is the Bloom nute from the trio set. It is highly concentrated so if you are basing dosage from their feed schedule you are guaranteed to overfeed. This is a nute you have to let the plant show what it can tolerate and we started at 1/4 strength to start. It salts up the medium fast .

Also , leaching your soil just to do “ runoff checks “ does more harm than good … as you continue to over water it to get runoff , you unbalance the medium further.

Plus , the most glaring issue is it’s an auto. . Autos do not need complicated feeds. Most bagged soils could carry it along for weeks alone.

Lastly , since you are mid point of flower ( plant finishes when it finishes regardless of breeder estimates ) you only have time to stop further issues , plant will not recover damage leaf. Flower formation can also be impacted by wonky feeding / environment and of course stress ( which can come from your hand - feeding and what not ).

Im using peat moss and perlite, the most accessible and affordable to me at that time. Regarding distilled water I use it because supposedly it helps to really know whats going into your mix other than that I have no reason to use it. I had been giving it heavy doses of nutrients during veg and flower it was doing fine until I flushed it during week 2 of flower. My question to you is do I just give it water from here until harvest or do I give it just calmag water?
