ppm increasing too fast!!!

Im using an ebb and flow with roockwool, hydroton and GH nutes. My nutes are 2 years old (Stuff floating in micro). I had root rot issues which I believe was from using to big of a rockwool cube and overwatering. My question is what could be causing my ppm to go from 900ppm to just over 1000ppm overnight?
I just drained, scrubed entire system and got rid of plants and started with new rooted clones. I also use 34% hydrogen peroxide in my resi. Do I need to change nutes?
Thanks

This thread already doesn't make a lot of sense to me. You are using old nutes that you are fairly sure aren't good anymore?

Why would you have brand new rooted clones being fed with water that has a strength of 900ppm? These plants need to be treated nicer my friend. The ppm is rising because the plants are drinking the water or the water is evaporating and the nutrients aren't being taken up at fast. When this happens it's an indicator that you need to lower your starting ppm. Probably to more like 100ppm for brand new rooted clones. What kind of water are you using? How many ppm are already in your water source?

I spoke to GH and they said I could use them with a lil HP. You are right about being too high to start. I'm using filtered water and it starts at around 500ppm. I will drain and restart with new nutes.

Your filtered water starts @ 500ppm? For growing hydro I would find a different water source. Something 300ppm or less, I've had too much trouble in my past with dirty tap water. But if you use it then you should only be at about 600ppm when it's all done. I would use very, very little and then bump them up slowly but surely. Every other day bump it up 50ppm or so until you reach the levels you want to get to. Read your reservoir if the ppm rises you have too high of a starting ppm, if it decreases you have too little. You want to get to a point where it stays the same.

What should my new ppm be? How should I feed them? Just H2o? How can I maintain 100ppm? Thanks for smackin some sense into me.

Listen to Laserburn. Back off the nutes, and get fresh ones!

Good luck with your grow!

Also remember that when your plants drink water they don't necessarily absorb nutes in an equal proportion so at times ppm will go up just because water went down and all you have to do is top off with plain water.

Just means up plants aren't as hungry as they are thirsty. Lower ur ppm and track it from there. If ur ph rises rapidly and ur ppm falls they're hungry so give them a higher ppm. If ur ppm is climbin and/or ph is dropping off lay off the nutes as they want more water. Its a very good idea to take notes on this it can help u optimize ur grow and isolate each strains specific needs to ensure maximum yield and potential are achieved.

It's of critical importance. I would just measure the ppm of your starting water, then add 100ppm via nutes. Don't worry about h2o2 until AFTER you have your nutrient levels squared away.

I suggest going out and buying something really simple like sensi 2 part or one of the zillions of other nutes. But regardless you should get new fresh nutes and give yourself a real chance at it.

Yes. Distilled and or ro would be good in ur case if u can afford it. Also (this is just MY prefference) but that peroxide seems a little liberal. Do at most 10% but ONLY after covering the net pots and res. If u have algea problems after that then I would add the peroxide

Thanks guys! I hate wasting 3 gallons of nutes! But i'm pickin up what you guys are layin down. Appretiate all the help.

I would just rather waste 3 gallons of nutes than 3 months of my life. You won't use 3 gallons of nutes in a lifetime anyway, go get some smaller bottles of fresh new shit.

Good luck

Yes! Sensi bloom and grow was the best sugg. I've seen yet. It is ph and ppm perfect and will save u a lot of hassle and money in the longrun. And figure the cost of 3 gals and compare that to the cost of 3 months that time (priceless) power, water, stress. Can't put a price on avoiding that. Lol
