I would say it is like a good runoff. What do your nutes say soil ph should be? I guessing it should be around 6.5. If you're close and you don't see any problems, then I would say push it until you see your max then back off. What are your ppm?

So my ph goes in at between 6.4-6.2 and comes out 5.4-5.7 is that like a good run off point

I started to have problems (lockout) when runoff went below 5.4. You should also check your runoff ppm.

Measuring runoff isn't accurate because it depends on how long the water sat in the soil equalizing, and how much new water displaced the runoff (potentially diluting it). You can google for NCSU Pour-Thru Method to see why these two factors are important. (To accurately test runoff takes an hour.). And, after you have your soil and nutrients dialed in, you shouldn't have to measure runoff. If it's dialed in, it's a waste of time.

But, when you're starting new soil/nutes, I think it's invaluable to measure runoff. However, only if you start measuring from the beginning and can watch the trend. While an individual test may not be accurate, seeing it go lower in flower can definitely save you some headache by flushing, cutting back nutes before the plant starts exhibiting lockout.

I don't measure it anymore. Sometimes I'll measure runoff ppm because I know 1250ppm (hannah scale) is when I start having trouble. By measuring ph and ppm when I worked out my problems, I could see a direct correlation between ppm and ph. PPM would rise to 1200 as ph dropped to 5.6, 1240 occurred about the time 5.4. 1280 was like 5.2 (and plant didn't look as good).

Those numbers may not be the same for you. For me, I'll occasionally check runoff ppm and I have a good idea where the soil ph is (whether I'm over feeding). I might randomly test the runoff ph, but I don't need to because things are pretty much dialed in and runoff ppm is good enough.

I only feed with nutes every third water sine my babys are small but this is it i did some thinking and im sure i just over watered these are two grape stompers cut from a plant in its first week of flower so as soon as it has a good root.system it goes straight into flower

Dude, your way of thinking is a recipie for failure. You're gettin way ahead of yourself. You can do what you like, but now you want to move into hydro and you havent even begun to learn how to grow in soil. For instance, those little baby clones shouldnt be getting much more than plain old water and thats it. Why overcomplicate the shit ? Your only gonna burn and kill them off. Plants dont need Bud Candy when there ain't no buds.
You desperately need to do some reading and some learning on how this is done.
Patience man, patience. Let them babies grow and give them a chance to grow up.
If they could talk to you, they would be pleading with you to leave them alone awhile.
