What is going on ova here?

Hi Everyone,

I am sitting here looking at my plant and I just can't seem to figure it out... Attached are the pictures, all Banana Kush. I have been watering them with the correct measurement of FUL-Power and Epsom salts to cure what I thought was a Magnesium deficiency. I did this every other watering to see if there would be any changes but here I am, clueless.

My plants are all different heights. The taller two are the correct distance from the light fixture. I have been trying to experiment with training so.. excuse the inconsistency.


Facts:

The plants were put into flower the first day of October, they're grown in Pride Lands Potting soil. They're in 3 gallon pots.

I use one 550 HLG R spec v2 for a 5x5 tent with a 6 inch ventilation tube running from the carbon filter. I also have a 4 inch inline fan boosting the air flow.

I have never had a problem with temperature, humidity or bugs during Veg or Flower.

Every drop of water these plants have received has been ran through a Brita filter.


Questions:

Should I feed nutrients and risk burning the plants since they're already in soil?

Should I just ignore this entirely (plants are fine) and continue going along with straight water?

Any Advice is appreciated, All input is welcome.


Thanks

The brita filter doesn’t filter anything it just dissolves some shit that raises the ph to like 8. that 8ph water has raised your soil ph and locked out your plants. I would water a couple times with pretty acidic water like 6.2-5 and they should start being able to uptake nutrients. Also, you’re gonna want to pour gasoline on the brita and light a match, make sure the flames are at least 3 feet high. last one is optional

easy solution, I'll give it a try and keep you posted.
