    Critical purple issues

    Hey everyone I'm a fairly new grower. I've done a few in the past but always with a 600 hps. Had 5 successful harvest with DWC with that set up. Recently I switched to a led light. Cost and heat yah know. I'm also using auto flowering seeds I've never used led grow lights before. I have the light on about 35% power. I use general hydroponics grow trio along with Cali-magic. I always check ppm and ph. My pH is 6.0 and ppm around 300. (I can't decide nutrient problem or light) I don't know what is going on with this plant. I have a tangerine dream in the tent with it the tangerine dream looks amazing. No issues at all out of it. The critical purple on the other hand is one sick pup. I've lowered nutrient level. Raised the light. I'm at my whits end. Anyone have any other ideas ? I will post pictures as well. The last picture is of the tangerine dream. Both plants are few days away from a month old.

    Give this a look, it may be leaf septoria.

      Not sure how to word this but from what I read in that article it kinda leans more to dirt and out door grows. Could this of come from my growing media? I used rapid rooters and the clay pebbles. Just trying to figure this out and how to prevent in future. I don't understand how i have one very sick plant and one that's doing amazing when everything has been the same for both plants.

    Favors calcium deficiency. Calcium is barely available at 6

      IMO it looks like ph issues or pests more than anything else. It doesnt look like calcium deficiencies to me as those are more rust colored and leaf septoria tends to look different. Are you testing res ph daily? Is your ph tester calibrated? Make sure you let the ph swing from at least 5.8-6.3 before adjusting.

        Get out your loupe and check for mites. I suspect the Critical Purple tastes good and the the TD doesn't.

          I have been testing pH daily and I did calibrate the tester just to be sure. I have the drops as well. This the first time I've had to raise the pH of the water. Ive been getting my water from a friend that has well water. In the past I had good luck with well water. Nast city water where I live.

          I will look. I just don't understand how anything could happen in a controlled environment

            All it takes is one little bug blowing in when you open your doors.

            Oh man, I have more issues inside with bugs than outside.

          Get a boogie blue water filter it attaches to your water hose and use that. I live in southern new Mexico desert, my tap is between 7 and 800 ppms ph of 9.3. I used to think the same and I couldn't use the tap, so I bought an expensive under the sink R/O filtration system. I've been using the boogie blue for about a year now with no issues. I either fill up 5 gallon buckets or water the plants directly with the hose. If you went more organic you wouldn't even have to ph water. I've been watering with 9.3 and soils are between 6.5 and 6.8

            Keep a eye on that hose filter. I used one on my first grow, it worked great. Didn't grow for three months, renovating grow room. Started new grow and had big problems with biological contamination first couple of weeks in my buckets. Couldn't figure out what it was? Wound up being that damn filter!

            Times 3! Get out that 30x zoom lens or microscope and look to the under side of those leaves.

          Also note that bugs like purples more than green.

            I too have a similar issue of purpling and it's not good. I think this is due to some strains that naturally look purple in colour, but it's generally a clue of a nutrient deficiency or exposure to colder temperatures than normal, which can depress THC yield. When I was faced with this issue one of my friends who is working in a weed dispensary shared these facts with me. I was growing my plant outdoor without any temperature adjustments. After this, I have adjusted the temperature and the problem was resolved.

              How do you adjust the outdoor temperature? Enquiring minds want to know. 🤔

              Its Voodoo, but one must be careful not to over do it.

            Yea how do you adjust outside temps? Purpling doesn't depress thc yield. Purpling is either genetics or it means your mediums depleted of nutrients. I grow organically and allow the medium to become depleted before harvest.
