Time to up the nutrients?

[Troon]

What you will see in the pictures below always happens to me every grow.

How I see it:
I notice the older developed leaves starting to turn yellow, at the same time this is happening the newer growth is always a lighter color than the rest of the plant.

It starts off slow and as more of the plant is effected with yellowing leaves the it spreads faster. The more discoloration the faster it spreads. It always starts off slow and then speeds up as it move along is all I'm trying to say. It will eventually consume the entire plant .

I also notice the top half of the fan leaves stem that are effected are purple. The stem of the leaf is only purple on the top side, the bottom side of the stem is green.

- The plant is 37 days old.
- I have two others that are showing the same signs as this one, and this has happened every time I grow around the same age, 30-40 Days.
-I am using advanced nutrients Grow-Micro-Bloom three part system. I have been feeding 2.5mL of each nutrient bottle per gallon of water since above day 10-15.
- I do not use any other additives or nutrients, the three part system is all I am using.
- I am growing in soil.

Tried to include what information I could. Thank you guys for your help in advance!

I'm running right now, Brother Troon, but throw me a link to your grow and I'll be there in a few minutes

I don't really have a journal just a thread in indoor growing where I post pictures and share some info about my grow. Not really what I would call a journal. There should be a link in my signature though if you're interested.

Avk. It's been a day
Random red stems, the inter marginal discoloration...
What's your pH running right now, Troon? Good looking growth, but a definite nute def.
I gotta get some sleep, I'll hit you up first thing. Besides pH, and how you're checking it, what kind of water and soil are you using?

And the ppm? Red stems are probably from low night temps? Also looks maybe a bit light shy, could get stunted. Have you tried backing out the lights a bit?

Well I only have some shitty cheap pH meter that doesn't work or at least I don't think. I do however have a pH meter for water that works well is there anyway I can use that? pH really shouldn't be an issue because I am using Advanced Nutrients pH Perfect Nutrients.

I'm using my tap water, have been the entire Grow. I have been feeding every water since about 10-15 days old.

I have never flushed the soil, do you think I could benefit by doing so?

Do not have a PPM meter. Light is just over three feet away from the tops.

Having a pH pen to check the water's pH when using the AN perfect pH isn't necessary I guess but it's a good piece of information to always have, how do you want to flush the plants without it? You only want to flush if you cockup, too many nutrients etc. Red stems are usually lack of P, but in case of the cheese I'd say it's either genetics or they all are hungry for P, given on the google picture search of the strain.

Well I am upping the nutrients from 2.5mL of each to 5.0mL of each and see what happens.

So you don't seem to think it's salt build up or pH issue due to Advanced Nutrients?

Im almost sure waita said p is a two tone effect like an old car top half bottom half kinda thing.
Only flush if its an emmergency,and only then if you put way too much of something in.

I think what's going on is in my search for perfection I am being shy with the nutrients as the last thing I want to do is burn my babies up. I've been feeding them the same amount of nutrients since I started giving them nutrients. All the nutrients that were originally in my soil have been depleted by now.

How long should it take before I see result from upping the nutrients?

Also everyone who replied is getting reputation.
