Ebb and Grow kit... HELP!

Hey guys... I was using House and Garden's line until they started to look bad like this, then I did a flush with 1/2 RO and 1/2 Tap for 3 days and then switched their nutes to GH's 3 part. I really can't even tell if they are recovering or even growing... I'm 5 weeks into flowering and there is hardly any bud on them...

My pH, as checked with Hanna's GroCheck pH/ec/TDS/C is 5.7-6.1, I check it every day and adjust as necessary. I've been doing reservoir changes every week because someone told me to, but I've been reading on here a lot and I'm noticing that a lot of you guys consider that excessive. My ppm's right now are 1300, with my water starting around 350 ppm, using 1/2 RO and 1/2 Tap. Reservoir temps are kept in the 20-23 C range by putting two frozen 1-gallon in the reservoir each day. I've been throwing 25-30 gals in there at a time.

I'm using the Ebb and Grow bucket system.

Thanks for any help, much appreciated.

Looks like nute burn...you measuring correctly????

I believe I am... I've been using about 80% of what it says to use on the bottle for the GH nutes, I figured 5 weeks into flowering that should be about right...

Anyone else?

What are your temps + humidity?

Well I'm using a Sentinel Environmental Controller so it's all pretty well controlled... Temps range from 76-83 and humidity never gets above 50%

Those plants look exactly like the ones in that long thread that popped up about the plastic tubing that was deteriorating, causing his plants to go toxic. He lost everything. How old is your ebb and grow, and did you buy the whole thing, or did you buy the controller bucket, and the other parts seperate?

The reason I'm asking is I also run one, and have never had an issue like that, and I also use the house and garden.

Do you follow the directions on the document that comes with them? It clearly lays out how to run each week of their product. You have to be dead on with the amount of nutes, and when to do start different products. Are you using all the different parts of the system?

I don't flush each week. I just keep mine topped off at the gallons I like, and add back nutes to keep my ec at around 2.

Did you ever figure out what the problem was??? I like the idea something in your system is poisoning your stock.

Yes, it actually was the hoses in my system that were poisoning my shit... I replaced all of those N-G-W hoses that I was using... User u.g.u informed me in My Other Thread that I started in the 'Marijuana Plant Problems' section that those hoses leach toxic plastic chemicals into the water.... He has a TON of proof to back him up including an actual water analysis showing the toxin in his water, and multiple pictures from other users using that EXACT same N-G-W hose, whose plants had the exact same symptoms.

Also check out Warning New Off Gassing Product! ... This u.g.u's thread on this particular issue that he referred me to when he saw my post... He's actually trying to start a class action lawsuit on these guys.. They can't be making hydroponic hose that leaks toxins into the water. God knows that that does to the smoke, too...
