Other than your leaves being light colored, there is nothing wrong with the plant.
Keep your pH in the range of 5.5 - 6.0
Don't water so much.

PH up? How acidic is the water before you ph up?
Well this is thenfucked part. I have to use this ro system built into my sink but ph is like 5.5. It’s weird. Ppm of like 30 though.

Do you have any beneficial microbes to put in that soil?

Don’t just use plain water at that rate. Bring your ppm to ~125 with your CalMag, then check the ph. Always add CalMag to your RO first (unless using silica, which should always be diluted first), then begin mixing your other nutrients, let it sit for a few minutes, stir and check/adjust ph.

RO can be a tricky bitch. Is yours a tank system or a filter? Is it a newer system? Are you on a well or city water?

Yeah man I’m on harddd well water. And it’s a tank system. Without it my water is like 990ppm. I can only get 5 gallons of water about 3 times a day. It’s a bit older I’m assuming.

What’s the perfect ph??

It’s needs to vary to intake all nutrients, for this reason I stopped ph’ing. If you’re meter is even a slight bit off you’re gonna be overdoing it anyway. I found I did more harm than good when I tried to ph my stuff

Are you sure your water is "hard" (calcium and magnesium)? I've done a lot of consulting with farms around N. America and I've never seen well water over 300ppm unless it's iron and other heavy metals which is typically associated with acidic groundwater. TDS readings measure all salts and don't necessarily mean the water is hard.

If ph is high i put a small splash of white vinegar in a 16oz cup of water go light if ph still high reapeat, same drill if ph is low but use bakeing soda this will raise ph, allot of people obsess about there ph i shoot for 6.2 but most strains can handle 6.0 to 6.8, i would give a light flush and correct if nessasary then go from there.

Most calcium-containing fertilizers are formulated with calcium nitrate. Keep in mind that calcium nitrate is potentially basic, meaning it will cause the pH of the growing medium to rise unless acid is injected or potentially acidic fertilizers are used in rotation. Large additions of calcium will displace potassium and excessive calcium can lock out potassium and magnesium, a deficiency of these other nutrients is a quick way to potentially diagnose excessive calcium.

There isn't anything wrong with those plants...not yet anyway. RELAX, breath, learn to have some patience. You are way over thinking everything and will probably cause problems that you don't even have.

Wow!!! That’s crazy hard. Have you ever had it analyzed for mineral content just to see what’s up?

If you are planning on staying/growing at your current spot long term, would upgrading your filtration be a wise use of resources? If you aren’t dealing with iron (Fe) there are prob a couple options that wouldn’t be prohibitively expensive, that would at least give you more daily flow and help save your appliances/fixtures.
What’s the perfect ph??
It’s good to use a range of ph’s depending on your medium and stage of growth.

A good range for soil is 5.9ish to 6.4ish. No need to be super precise. Somewhere floating around is a chart that shows recommended ph for different stages of flower to help the plant uptake the proper nutrient load.
