Is This Nutrient Deficiency or High pH Levels

I’ve been growing this plant for 4 months now and I was thinking about switching it to flower but I started seeing the leaves turn yellow from the edges and feel brittle. I’m feeding it nutrients so I don’t know what this could be. Any help will be appreciated. Thank you.

how long has it been in the pot it is currently in?

what are you feeding it? how much and how often?

lighting? Temps? RH?

What medium are you growing in?
What is the EC or PPM that you're feeding?
How often are you feeding?
What is the pH of the feed?

Don't think about flipping to flower until you get this sorted out or you'll be wasting your time.

if you're only running the blurple I would be skeptical of it being light burn

it looks like p or k def but why is what we need to determine to know how to fix it best

I’m feeding it general hydroponics floramicro and floragrow. I feed it every 5 days or so. I haven’t started feeding it florabloom yet because it’s still in vegetative. Once I flip to flower, I’ll feed it florabloom.

I’m growing it in potting soil.

I’m not sure on the pH of the water because I don’t have a pH tester right now, but I’m using regular purified bottled water to water it and for the nutrients I use filtered fridge water. I’m thinking the pH might be too high in that water since it’s drinking water. Is there a way to lower the pH without adding a pH balancer? Maybe a natural way?

If you're only using 2 parts of a 3-part nutrient, that's gonna cause issues.

Omitting the bloom means almost no Phosphorous or Magnesium and zero Sulfur.

You do use less of the bloom component in veg, but it certainly shouldn't be omitted.

That looks like you might want to check for hemp/russet mites. Your probably going to have to check with 50 plus magnification on the underside of the leaves. Also try to keep that plant away from other that are completely healthy till you work out whats going on. Good luck.
Ps have you been letting any pets near those plants ? If so thats probably not good idea.

Only you will know if its ph or nutes, you know what you put in.it will look the same because ph problem is just when the plant cant suck in nutes soo it feels like there is nothing inside.

As mentioned, you need to use the bloom part.

For vegetative, you need to use equal parts of micro, gro, bloom. Or, for aggressive vegetation, 2/3/1 of micro, gro, bloom. In flower, the ratio changes to 2/1/3. You also need an EC or PPM meter to get the correct strength. Bottle direction are too strong because they are general uses (e.g., tomatoes need at least double the nutrients that cannabis needs) and GH is not a cannabis specific nutrient line (i.e., the dosage strengths are not made with cannabis in mind).

I am growing indoors so I don’t think it has any pests.

It looks like your nutrients are out of balance. You're feeding way too often in soil every five days. How big is your pot and your plant and how much water each time you water? Can I see the whole plant that would help too? I think though from what I see now and what you said you are way overfeeding it and possibly causing a lockout of other nutrients with the overload. Just use water for the next two waterings with a good amount of runoff.. I dont know if you're watering too often or what your watering looks like so Im not sure if you're watering it too much but you probably are.
