    Day 46 Flower

    I played with my camera a bit and was able to get a decent picture of what I am seeing as far as a potential deficiency. I know potassium and magnesium can look somewhat similar but the fact that the tips degraded a bit leads me to think it is potassium. Again, I have been feeding so light I really think this is what it is. To be safe, they all have been given some HPK, as I mentioned above and some Cal-n-Mag. Things seem to have settled down so I trust it was one or the other. I am certainly open to opinions if anyone thinks I have this wrong.

    My soil pH at about 7.3 (not knowing how accurate a slurry test is) could also be affecting things but with using Earth Juice for many years in the past and never having checked my soil pH...I'm not sure if my pH would be throwing me off significantly enough to cause any problems.

    One other thing, what do you guys think about me having my RH at 35-40% at this time in flowering? To low...about right? Just curious as when I was flowering in a tent years ago, I don't recall paying much attention to it but I am aware it is something that can cause some issues. My temperatures are running about 65DF lights off and 73/74DF lights on.

    Anyway, as I mentioned above, things seem to have settled down and I think things are fine but as growers, any kind of issue is always concerning...especially when one is this far along in flowering.

      Hey Jerry, I think the humidity is good,low enough to escape the mold.
      Too low RH is more of a problem when the plants are in their baby days. It's always the too high RH which kills the buds.
      Just water them more if they should become thirsty. They're like us...when it's hot they need more water and sweat it out. I dont think you need it higher or it will bite your bum in the end.

      To the burned marks on the plant...I'll tell you which way my thoughts drift, but do your own research...seriously I dont want to stuff things up for you:

      Am I right to say you saw it happening on top of the plant first? In that case I would tend to assume it is nute burn instead of potassium. Nute burn shows up anywhere,but potassium usually starts from the bottom. They also looked well fed to me..and I double checked your old pics and they always looked stunning..no signs of keeping them hungry.
      I add a screenshot of your last picture showing why I think it is nute burn.
      That's just my two cents..I hope someone more experienced showes up and corrects me if needed.


      Maybe do another ph test.. to be sure to be sure
      If you ask me, there are two options to see if it is a nutrient burn or a potassium deficiency:

      - give them potassium and see if it gets worse
      Or
      - flush them, give them 30% less nutes and see if it gets better

      I'd travel with the flushing, i think it easier to feed more if it was the wrong decision.. then fighting a overdose.

      I really do hope you fix it quickly, for all that effort you put in, you deserve a fat harvest.

        Hi Ivan, funny you mention flushing. I did that this morning to all 5 plants with the water at around 6.2 pH. I checked the initial runoff...pH just over 7 and a tds of around 1700 ppm! You all know how lite I feed. Hard to believe my initial runoff was that high but it was. Anyway, a flush was the right call. I’ll let them drink what I threw at them today and reassess then. I am wondering how much my hard water is hurting. This is my first grow in this new house. A tds of 200+ ppm is awfully high. I was actually pricing RO water systems today. Might not be a bad investment. I’m also debating moving away from the peat based ProMix and getting back to my roots...soil.

        All in all, things aren’t that terrible. I’ve seen some grows that really go bad and not even make it to harvest. I’ll get there but I likely have already given up some yield. Funny thing is my OPG cross has never batted an eye, flowering very strong with a dense top cola and nice secondary buds. It’s budding stronger than any of the AS’s.

        I’ll keep ya all posted. Happy growing!

          Yeah, youre right.. It's not bad and you acted quick. I dont see an issue either. Let's just hope it isn't potassium deficiency

            Hey Jerry, are any new burns showing up?



            I just read about Kanamu Pacha soil. Sounds a bit frustrating to water,but besides that very promising. Have you heard of it?

              Hi Ivan,

              I had never heard of that soil...had to look it up. Now I wonder if anyone distributes for them in the United States. Shipping soil from Germany would be a touch cost constraining. I wonder how it would compare to something like a Fox Farm Ocean Forest?

              Everything seems to have settled down. They are all drinking the fresh water well and I can’t see that any additional necrosis has settled in.

                So I have culled all of the Asian Sensations that I had vegging. This OPG cross that I have going is the worthy one for my next run. I pulled 8 clones, plan to give two to a friend, and I will then plan to run 6 of the OPG cross. I’m thinking both the AS’s and the OPG cross will go 10 weeks. About 16 days to go.

                  You should be closer to the soil than me. They say it's from South America.
                  It's very heavy and holds heaps of water. Needs slow watering but you might have to water a third less through the whole grow.



                  Good that you see no new yellowing.

                    Looking at your posts from 10/26/20 forward - with this latest one stating you found a high TDS in your runoff - is making me think you got some kind of pest in the root system. Seems that latest photo is consistent with the lightening of the pigments a plant gets when it is hungry - it doesn't look to me to be an overfert problem. Since you appear to have had sufficient nutrients in your soil, I'm thinking the roots might be damaged by pests and that is negatively affecting uptake of nutrients. PH doesn't seem far enough off to me to be causing nutrient uptake problems.

                    That said, it doesn't look like it will prevent you from finishing. However, it may mean you have to keep your clones for a subsequent grow for evaluation. If this grow wasn't optimal, you may not get a clear picture of how good each is - although, hopefully, you will be able to determine the relative quality of each so you can make a decision on a "keeper". Then again, it doesn't look like that huge an issue for the plants and if your flush improved the conditions for them, any difference in the finished bud compared to a grow without this issue is likely to be small, in my opinion.

                    They look like quality plants, in general, though - nice long buds and good calyx to leaf ratio.

                      Day 54 Flower

                      You're absolutely right Chester. I hadn't thought about some pests possibly down with the roots. Is there any way I can definitively know if that is the problem?

                      As I mentioned, the AS's are out, I pulled the cuttings that I had in the cloner this morning. They all had rooted but not knowing what these were given they were just bag seed, I would rather, at some point, dig into some known feminized genetics I now have laying around. Some of the RGSC seeds I have sound very interesting, I have some Female Seeds seeds on the way, I have Brother Mendel's Tropic of Censer that should be arriving soon, a White Widow clone and maybe a few others. I don't know much about the WW clone but it sure would be neat if it resembles anything close to the WW of the mid-90s.

                      A picture of my (NL#2 x Chem) x OPG. Still a bit to go before harvest.

                        Beautiful structure on that plant, Jerry! It certainly would be nice to see old school WW make a come back too.

                        As far as possible root pests go, it's usually either fungus gnats or root aphids. You don't have fungus gnats because you would have seen them flying around and it doesn't look like your medium is wet enough for that. Root aphids may be undetected - but - I think you would have seen worse damage by now if you had a typical root aphid infestation. You are in a weird in between state - it could mean any bad bugs have only a slight advantage over some good bugs who are fighting them - or, it could mean I'm completely wrong about the root bugs possibility.

                        I'm on the fence at this point about what it could be.

                        Although it didn't seem to me that your PH was off, perhaps these particular plants just like it a bit lower. If that's the case, you already fixed it with your flush and you'll proceed to harvest with no new damage to the plants.

                        At this point, I would consider any problem fixed and proceed towards harvest while keeping your water and nutes under 7 PH.

                            Day 61 Flower

                            Just a quick check-in. So I cut down one of the AS's last night, she was ready. The other 3 AS's and the OPG cross have a little bit to go but I'm expecting they will all be down shortly. The OPG cross remains the shinning star, no big surprise there. Everything in the veg tent remains positive. I have the OPG cross mother plant, 2 potted up and 6 cuttings that are just starting to root.

                            I'm excited to have this grow behind me and get a winter run going. I learned a lot about my new grow space which was the primary objective of this grow. The seeds from Brother Mendel arrived (FYI - found him on a local Growers Facebook page and was impressed with all the positive reviews). One is Miss Mendo '06 = '06 Mendo Purps x Tropic of Censer(Purple Cut). I also grabbed his pure Tropic of Censer to try given he crosses it to many of his strains. I have too many seeds now, I don't know what I will run after this next grow! I have Female Seeds C99 that might have to be the next one! I've never run Cindy but I have run Apollo 11 (Jack Herer x C99) that is my favorite plant I've ever grown. Hats off to Bros Grimm for that beauty.

                              Well done Jerry, I'm close to finish mine soon too. I hope you enjoy your harvest as much as i enjoyed watching your plants grow. Good luck for the new genetics.

                                Thanks Ivan. The other three AS’s and the OPG cross came down today. 64 days flower. All were showing just a few amber trichs with the balance being cloudy so a good time to give them the chop. I’ll come back for a smoke report once we get a few weeks cure. Thanks all for following along and giving me some guidance along the way. A few tweaks to my system for the next grow and I expect a very good next run. Happy growing everyone!
