Did you ignore my response? Instead you respond to suggestions that were not at all helpful.

Enjoy your nute burn.

every time my res goes down, my ppm gets higher.. which means the plants are taking more water than nutrients ... so i am just putting more water in with no nutes...

No. It should be like 5.5-6.0 for hydro most people try to maintain 5.8.

how do i increase it? more nutes? if i do this, it will be well over fed.

You need to get some pH down and might as well pick up some pH Up while you're at it. You can put some distilled vinegar in the tank for now to bring it down but I wouldn't rely on that forever, it may interact with nutrients in an adverse manner.

Your plants will continue to be unhealthy and eventually die, what's happening now. From the looks of your leaves you have intrevenal chlorosis going on which can only get worse and goes down hill fast. pH is a very important part of hydro if you're not going to maintain it correctly then you should go back to soil.

i am maintaining it correctly. since i put nutes inside, it still had a reading of 6.9 . and its 6.9 now. so it was always like that.

Listen to me here. You now have to raise your ph to 5.5-6.0. Your plants are going to be fucked up until you get the fact that it is important. Certain nutes lock out at different ph levels. Maintaining a ph of 6.9 or 5.0 in hydro is NOT maintaining it correctly. Adjust your ppm/tds to an acceptable range. Look up lucas formula for some tds/ppm ideas. People are here to help you and give you advice....listen to them.

i got the ph colours wrong... the ph is 6 not 5.. and when i used my ph meter , it reads 6.5 ..
as for the nutes, i do use the lucas formula... exact how i was told.. my ppm is properly updated.. my res is refilled using the lucas formula...
and also, its only happening to several leaves at the front.. iw ould say 10% of the plant.

6 is bettter!! Have you calibrated your meter lately? Mine has to be calibrated all the friggin time. How are your rez temps? With the lucas formula I have to add cal mag. Not saying thats your problem. Give them some time to recover now that your parameters are getting better.
