    I am a bit conflicted. The first set of pictures you posted seemed to indicate a deficiency. The tip burning I see on the middle section made it appear a bit like slight nutrient toxcicity, but I don’t see much going on at the top of the plant. Is that correct? It’s a bit hard to tell from the picture. Based on the fact that your runoff was 900ppm, it’s pretty hard to dispute it is a deficiency. I am going to defer this one to Chris because I’m just not sure what’s going on 100%.

    I can confirm that does appear to be nutrient burn. Is that the plant the leaves are from? You should probably try and get a runoff test watering cycle and post those numbers, including input water ppm/ec. Nute burn typically causesĀ  the tips to rolling inward like that or to drop straight down like they are really heavy at the tip.

    <p style=”text-align: left;”>Looks a bit like a phosphorus deficiency. My first thought was the soil being too wet also, but if you have a moisture meter that shouldn’t be it. You haven’t noticed any soil pests either I imagine?</p>
    Yeah, a more inclusive picture would be helpful.

    Are those lower leaves? Are they getting decent light?

    No problem.

    I think you are viewing the situation wrong. Warmer temperatures speed up enzymatic processes. I would rather have a higher temp and lower vpd than the converse. The plant has the ability to regulate its water consumption by opening and closing the stomata. It doesn’t have the ability to regulate temperature in the same way (yes it can cool itself down through transpiration, but it can’t generate any substantial heat). In an ideal world I’m shooting for 77f and 70rh for seedlings. Too much heat and they can get a bit stretchy.

    Realistically 2. You could squeeze 3 in there but with 15 gallons you are sort of overdoing the pot for the space. The plants will never get large enough to utilize that root space properly. I’d drop to 7gal and try for 4, but I like to push it.

    Q1: Depends on sexual stability of your strain. If you have solid genetics then hst before week 5 is acceptable when the plant might hit the light. If you are growing an unknown plant then i would just try and tie it down.

    Q2: When you stop pruning larf depends on how much work you want at harvest. You could continue to prune bottom larf through week 6 and 7 if you really wanted too. You have been through enough grows at this point to have an idea of how buds will dry. If it’s going to be a pain to trim, I remove it. This would hurt many growers feelings. It could be washed or pressed usually, but at the expense of costing time when trimming. I think everyone gets to a point where they just don’t want to deal with larf eventually. Plus, if you are pruning lowers you can look for nanners and other late stage gremlins better imo.

    When ph drops in the res that quickly it’s usually caused by a small number of things in my experience. You have bacteria or algea in your res that’s releasing exudates that are altering ph, your plants are drinking water too fast, or you are evaporating water too quickly with your aeration.

    Are/is your ppms/ec going up, down, or staying the same?

    Another possibility is that elements in your tap water are combining with your nutrients and falling out of solution.

    Yes, adding too much ph up/down can skew your ratios and cause issues. 2ml per day doesn’t sound too bad though honestly. 5.8 is ideal but bouncing between 6.5 and 5.5 is perfectly acceptable.

    You should dump it or feed it to other plants if you can.

    <p style=”text-align: left;”>Based on the information you gave I’m not sure it’s the light. If you have a ppm/ec meter I suggest you do a runoff test and post the ph and ppm. Lowering light intensity is always a good idea when you have issues though. Sorry my initial response didn’t do the trick. Was there anything that you can think that happened before they started going yellow?</p>

    Your picture didn’t upload. Could you try again?

    Looked up the product. Not a huge fan of the ingredient list in all honesty.

    Mr Grow It has several videos discussing that topic on his grow talk podcast. You can also check out Green Goblin 510 and Build-a-soil’s channel.
