Here is an excellent thread with good photos about different problems.

One last thing.....you may want to readjust your formulation that you are using and drop those plants back to about 1000....if they were my plants this is what I would do at this point:

RO water (or distilled)

CalMag.....450ppm
Bloom.......450ppm
L Karma.....100-150 ppms.

And thats ALL I would give them. 1700 at that age is just wild. :wtf:

Keep your ph between 5..5-6.0....check it as often as you need to to keep it in line.
Weedhound Reviewed by Weedhound on . 5 gal DWC Flowering - advice / formula needed I'm flowering two plants, usings 5 gal dwc buckets. Right now all I'm using is: Hesi Bloom - 60 ml cal-mag+ 25 ml liquid karma, 30 ml Hesi super vit 5 drops the ppm turned out pretty high (I was just going by the dosage on the bottle) I think it was around 1700 so I deluted with more water and brought below 1500. I'm using six 42 watt warm CFLs, two 30 watts and they seem to be slightly cooler cfls, and 4 6500k 26w cfls. Rating: 5
