Help!!! What am I doing wrong?

NotAGreenThumb · May 10, 2009

I think my plants are over fertilized. I'm using Botanicare products in my deep water culture system at 1/8th strength and still my leaves get this burnt look. I keep decreasing the strength of the nutrients and they still come out this way. Any ideas?

No, I've not tried flushing. It is my understanding that flushing is something you do when growing in soil. I am growing with hydroponics. I do change the water and nutrients every 2 weeks.

That is crazy. Have you checked ppm, ec, and pH? Looks like something pretty funky. I hate to sound like an old nag, but are you absolutly sure you are adding the correct amount of fertilzer?

im using a bubbleponic system and all of the sudde my roots have a brown line and are turning browner as i type this does anyone have any advise?

flushing it just when you give a plant plain water. doesnt matter if its in soil or hydro. that my friend is nute burn.

~sin~city~ · May 10, 2009

how do i fix it?

~sin~city~ · May 10, 2009

am i supposed to flush it and just give it plain water?

Extortion22 · May 10, 2009

either give it straight water for a while so it can flush out the nutes, or most deffinately cut back hella on the nutes you are adding to the water. either way you are feeding way too much and its getting burned.

Extortion22 · May 10, 2009

oh also check the temp of your water. I just read your post about brown roots. if its too warm then you can get root rot.

PH is under 6.0. I've rechecked the manufacturer's instructions and I'm definitely using 1/8th strength. Not sure on the PPM because yesterday I flushed the system and replaced my Botanicare nutrients with some Fox Farms that I had.

~sin~city~ · May 10, 2009

so wash out the resevor and everything and use plain water..
thanks so much dude!

growing in hydroton

WillyPhister · May 10, 2009

You need to swap the water in your res with pure Ph adjusted water for a week or so to let your plants recover.

~sin~city~ · May 10, 2009

~sin~city~ · May 10, 2009

WillyPhister · May 10, 2009

5.8 is ideal if you can

~sin~city~ · May 10, 2009

~sin~city~ · May 10, 2009
