Hello everyone, i'm new on here and was hoping to get some help,


Strain: unknown
Soil: pro-mix bx
Light: 600w HPS
Temp: 77-65
Nutes: General Organics go box

I'm 6 weeks into flowering and stared noticing a few brown spots on the leaves about 2 weeks ago and the problem kept getting worse, I flushed the plant with 3 gallons of distilled water (runoff was at about 600ppm and come down to about 300ppm). I gave her a feeding 2 days after but the problem is getting worse. I've been using the feeding chart on the GO box and haven't been PH adjusting for most of the plants life but started to when I noticed the problem. In addition it seems like purple sports have also appeared which had me thinking it was a phosphorus deficiency but the nutes have plenty of that.

I've been checking for bugs and haven't seen any.

I also grow in 5 gallon buckets and have noticed that the soil stays wet for awhile, There are plenty of holes but I only water about once a week.

Any help is greatly appreciated,

Thanks,

Severe nute/salt burn and there is nothing you can do now, this problem was created weeks a go and is set in.
Over feeding and/or letting pots dry too much too often lets salts build up and burns the roots.

Chunky may have hit the nail on the head, looks over watered are your pots extremely heavy?
I have had that same thing happen, what i did was, now this may not be for you but, I took a piece of half inch plastic water line rigid ( hard) and pushed it into the soil down to the bottom of my pots, that let my soil dry out, I use HP Pro mix and have seen my leaves do that same thing and the holes i poked into the bottom let the soil dry out and they looked better in a week, came back nicely.
Good luck hope you get it figured out.

Hey thanks for the reply,

Yes the pots are extremely heavy, I drilled many more holes in the buckets hoping it would dry out a bit more but its still very wet. I haven't watered one of my plants in 9 days and the pot is still heavy. I was worried that the roots are being suffocated by the lack of oxygen but that plant is looking great. I also had a tendency to not water till I had runoff thinking it would take even longer to dry out, which probably caused lockout .

most likely a ph issue. find out your ph level

Thanks, yeah I think the PH was off, both the Pro-mix and Go box mentions there is no need to PH adjust so I didn't. I think this is because the microbes in the soil would regulate the PH.

I think the problem is that I would water with mostly tap water, sometimes I would add a little dechlorinator but not always. My tap water comes in at 80ppm and I thought that was fine to use. I think the Chlorine or Chlormine killed the microbes and the PH got way out of range. After mixing up nutrients the PH would be around 4.5, I also tried adding PH up sometime but I heard that also kills the microbes. I recently started using distilled water that I bubble through an air stone and add a bit of sodium bicarbonate to raise pH, may start to use dolomite lime instead.
