potasium def???????

A little bit of background, The plants are about 2 months old, I started in a soilless mix with GH flora series and ran into some brown spot issues so I switched to a 20-20-20 for a couple of feedings and they started to look better so I decided to transplant from 1 gallon to a 3 gallon for flowering. When I transplanted them I used a 10-52-10 starter fertilizer and now I have this issue with most of my plants. They are under a 1000w MH 80f with light on and at lowest 58f light off. I just watered them today with Ph'd water. Any info would be appreciated.

10 52 10 is not a starter? You have several problems and a 1000 watt light..It is a conundrum.

nute burn like a mother....back off the 10 75 10 or whatever it was...find a nice veg with the n higher than the p and k......

I used the 10 52 10 because I thought that it was good for transplanting? what do you mean "several problems with a 1000w light?

The more light they get the faster the neut burn kill them. I would flush...subdue the light for a few days. diffuse it.

"They are under a 1000w MH 80f with light on and at lowest 58f light off".

that is way to much of a temp swing you want to keep it +/- ten degrees and 58f is way to cold. I try to stay in the 67f-77f area

58 degrees IMO is too cool;(

I find that they have not gotten any worse in the past couple of days, do you think that it would be okay to just give them water for the next couple feedings or would you flush forsure? Just asking because I have a couple few plants and they are all in 3 gallon pots and that would take alot of water, unless I could use tap water but I would assume that is a bad idea correct?
Thanks

Do not mess with them if they are OK Lucky guy if they did not get too burned.

if it aint broke dont fix it.....

do you guys think that just 1 feeding with the 10 52 10 could have burned them so easily the product that I used is http://plant-prod.ca/product_e.php?id=352&category=78
Thanks
As far as fertz go I would like to switch back to General hydroponics flora series for my next grow because I hear that it is some good stuff, but if any of you have any good recamondations as to what to use for veg and flower it would be greatly appreciated.
