How to Dilute and Feed. And fight for life.

I have a Ebb and Flow table that is running perpetual PPP from Virvana.

ph 5.8 tp 6.0
RO water
49-51% R.H.
600 Watt HPS
Hydrton
6" Iline for air cooled hood.
18" Osc-o-lat'in Fan + 10" stationary.

My plants seem to burn if I use any solution of 650 ppm or more. So, I mix my nutes acording to the Manufactures directions (GH) then dilute with RO water.

My question is how do I make sure my ladies are getting enough of the bloom nutes and everything and not burn them?

I am having to figth root issues and gnats as well. It is classic, everything was going go, and now it seems to be falling apart.

I am still pulling plants, but I am having to pull them earlier then I would like to keep them from dying. I have some pictures of some of the leaves and a pciture of one of the buds harvested.

They seem to almost have a Boron def, or it could just be because of the root issues.

Also, as the plants get older the small "sugar" leaves at the top of the plant turn beige dry-up and die.

Please help. I'm still growin'. But, I know if I do not get this under control it will come back and kick me in the ass.

Hey Rider,

Nice looking buds you are getting out of that setup.
I had similar problems in a perpetual grow in hydroton. (led/t5/400wcabinet Grow)
Once I finally got it through my head they didn't need what the manufacture recommended and I started my res at 700 ppm I had much better success.

What I didn't do until this grow is use cal mag. i wish I did. I am in week six of flower and I have not even seen a yellow leaf. It works man. I would say pick some of that up and mix your nute load including that to 650 PPM. Don't worry about not getting enough nutrients to your plants, Get the right nutrients to them and let the genetics take it from there.

My 2 cents.


* you know, those leaves almost look like they were burned by a light.

I am getting some bleaching. The light is right around 2' from most of the plants, but there is some bleaching going on. I have a fan blowing across the top of the plants, but it still shows the signs. I have seen people on here saying bleaching does not happen, but I have seen it first hand.

I think it is root issues I am fighting now. The plants are starting to show signs of stress, that is why I going to try Hygrozyme or SM-90.

And thank you for the complement. I keep trying to get it better and better.
