So I know the purplish is phosphorus deficiency. I flushed them mabe 3 weeks ago and began to give them fox farm trio. I give them half a dose every other feeding. I test them using my meter to see what the ppm are before feeding. I wait until there at 200 ppm until I feed. I dont get get what I'm doing wrong. Didnt give them water yet so don't know whats the current situation with the ppm.

N - P - K underdose.
Anytime you see yellowing fan leaves, starting from the lowest leaves, you have a Nitrogen deficiency.
It is a good detail to familiarize yourself with and keep an eye on.
They should perk up again, no worries, they still have a ways to go.
 
Whats going into the soil now. Upped nutes to 3/4 dose

Stop looking at runoff or what you think is in the soil. You need to maintain EC levels.

What are ec levels? Im experimenting with nutes to say the least. Last year I burnt the crap out of them . They look better than last grow tho, so thsts good. They are going on 9 weeks. This Saturday will be 9 weeks
 
Ive done bone my photos and autos the same. Have never had issues, could simply be the strains Ive been growing though. Auto AK47, Photo White Widow, Photo Gorilla Blue, Auto Strawberry Cheesecake. That's what Ive grown over the past year with that ppm config.
 
EC is electrical conductivity or salts in the solution. Don’t follow nute directions add them to water until proper EC

Basically, EC is a conversion from ppms. Same thing, different number. More commonly used because there's only one scale to EC where ppm's have three scales depending on your part of the world or meter of choice. So, if you say 600ppm, we don't know if you're feeding 0.8ish EC or 1.2 EC. That's a pretty big difference.

I read my runoffs because it tells me about the pH and the EC levels and makes it easier to maintain with less guessing. E.g., I discovered I had a bad tub of a nutrient when I saw the pH rising in the runoffs.
