Nute lockout in DWC?

Theres me getting all excited i had some replies and its just you guys squabling
I went up to 500ppm yesterday and she didnt like it - it had risen to 800 this morning so back down it went, to 500.
But she still looks very unwell. Im trying to take on what youve all said about reading the plant, if i do this she seems to be saying "feed me!!!" but if i read the ppm meter its saying "dont feed me, i tried 500 and it shot up to 800". So im confused. She definitely looks like she needs something!!
I reckon im over the worst of the nute toxicity but i really helping getting her back to health!
Cheers!

Just feed at 200 ppm to start with. Not understanding why your trying to kill the plant off with excessive nutes. It's not gonna die with just 200 ppm but will if you keep up the idea that you need to burn the leaves off with nutes. Also lower your pH to 5.8, it's not gonna rebound in a day, may take a couple days to put out new growth. How the roots look? Burnt up? Brown with algae? Do you have bubblers in the bucket?

Yellowish leaves will not green up only new growth will show you if the plant is getting better. I'd add some hydroguard to the water.


For starters I always go 1/2 of what the bottle says on nutes strength. And check water to see if it's eating or drinking. I have some plants now that I mixed nutes at 350ppm and they are slightly rising and plant is growing very well. That tells me that the plant is not needing that strong of nutes. A couple more plants I had to increase ppm to 400 because they were dropping the ppm down.

Play it safe at first with mild ppm levels and watch your pH. I just had that problem and I monitor mine daily to check risenor fall.
I have one plant that loves it at 5.3 And didn't like it at 6.2.

Thanks for this thread, it hopefully has helped me! My first grow and I have stressed it to hell, I am surprised it's still alive! First issues, not enough of a gap between cup and water level so I had a bad case of root rot. I can't get hydroguard for love nor money. In the end I cut the slimey root ball off, which obviously stunted my grow. Roots are very healthy now. Then I decided on a whim to go to 1900ppm and perform supercropping. My plant now looks like OPs first photo. I reduced the ppm for 1000, but after this thread I have now reduced to 500 with the idea if the ppm rises I'll reduce to 200. pH has always been between 5.5 and 6.1 fluctuating.

OP how did your plant get on in the end? If you can remember 2-3 years ago!

Thanks

Yeah she pulled through. Until I was a dumbfuck and let my bucket run dry 3 weeks into flowering and she was toast.
PPm and dwc, and I've done 4 since this grow - start low, 2/300. If it falls, raise it 100 or so. The plant will let you know if she's happy or not. PPM goes up, its too much, she's not feeding, drop it. PPM goes down, she's feeding, raise it slowly by 100, 150.
If you're at 500 and it rises I wouldn't go down to 200, too big a drop. 350, 400 would be ok.
Its such a great way to grow. Cant imagine anything better. When you get it all dialled in the growth rate is mind blowing, explosive growth.
