Hello! I just joined the forum, it has been a lot of help so far; I finally joined, I hope I get some help :3

I just started growing four plants, it has been six days. At first my ppm was going up every night because I did not rinse the hydroton (careless mistake, I know), now the ppm only goes up or down about 10 pts a night, but the PH goes up an average of .3 (<---that's good, right?)

(except for the day it went up from 5.4 to a 4.5, but that day I measured it right after the light came back on, I was told that could be a factor; by the way, is that true?)

If this is true, then my mistake was to measure it too soon; after I balanced the ph the ppm had gone up so much I had to dilute the nutrients, now I'm scared there are more PH chemicals in the water and not enough nutrients, and I will be changing my water tonight after the new water is ready to use (it has been turning for 12 hrs right now)

I originally reduced my ppm to 330, because it was the first days and my plants looked a little yellow in the tips after the (one is even sagging a little, but it was like that since the moment I put it on the bucket). Now, I KNOW the key to this is observation, and that I do in abundance, but no matter how much I observe...it has only been 5 days (duh!).

I reduced the ppm because the plants looked like they were yellowing, but this could have also been stress, and from what I see that plants are not getting any better or worse; the yellow tips did not advance, but the yellow parts turned a darker color and are now folding in a little (but that is normal, right? the dead parts are getting disposed?).

From what I have been reading, 330 is too little for a plant older than a seedling, but I am scared of over feeding them; should I keep the ppm on the low for a little while longer to reduce stress?

I know this is the universal question, but how do I know I am doing it right?

I read that if the ppm stays steady-ish, it means the plants are not eating or drinking too much; so if my ppm only fluctuates a little, is that a good thing?

Is there is something I should had done the day my Ph went up a whole point after I turned on the lights (wait an hour maybe?)

If this happens again (I reach a point where I feel I have added to many chemicals in the water), would it stress the plant to just change the water to a properly treated water?

I would really appreciate the help, this reads like a tight community, I hope you will accept me :)
I will introduce myself later, gotta go to work ;)
 
It would be much easier to answer ur question if we knew what kind of system u had (RDWC or DWC bucket). What nutes are you using? Are your roots in the water yet or just in net pot still.

Pics are always helpful also
