Hardly, raising RH into the low 70s with temps above 80 is incredible in flower. Air circulation is key. Stomata open, nutrients flowing. Plants love it.
you don't seem to understand. i'll try again: if your nutes have enough P and K, adding more does nothing. plants don't eat more nutes just because you add them. that's not how things work.
so does mold.
You seem a bit hostile with your ignorance. Your plants will benefit from additional P + K after week three of flower. Cannabis nutrient need shifts to these elements at this time. Jack's doesn't have the P or K to min/max this nutrient push in my experience. It's a base nutrient. The point is, you're leaving yield on the table, assuming your grow is dialed in, which might not be the case with you, and that is fine. Jack's serves all of us well enough as a stand-alone.
You're not going to get mold @ 70 RH in early and mid flower, dropping to 65% if your air circulation is poor in late stage. However, you'll see notable benefits in terms of plant health getting your VPD in check.
Fair enough - I just think enough agriculture research has been poured into these crops and similar to conclude P and K used at the right growth stage is easy and effective. And I do not think any base nutrient supplies the optimal amount when it's needed - and it shouldn't. That's the beauty of these base nutrient programs. You get good results leaving it as is, and you can push things even further by the addition of simple inputs timed correctly. No doubt people are overfertilizing. Overferting and lockouts because of it are the most common mistake you see on cannabis forums I think. I love the picture of your plant stalk a few pages back, really cool.Next time someone tells you that you need a PK booster in flower you tell 'em
The world needs gardeners like you to figure out the complicated shit for simpletons like me
While I appreciate that graph, it leaves many questions unanswered. Specifically, what was the feed program, which lead to the results shown in the graph? If a different program was used, would the results change? Most likely. Things to think about.
Post harvest dry and cure plays a far greater role in how the dried flowers burn. Excessive nutrients don't "build up in plant tissues" that cause oddly burning flowers
This isn't a new frontier in cannabis growing. Soil Testing along with tissue analysis of crops has been used and is being used to increase production across the planet. I do understand the point of concern you're making. You're using it and comparing it to what is known about cannabis nutrient requirements in various stages of growth and using it to guide you, not only in making sure you're supplying the right thing at the right time, but also that you're not oversupplying one as you antagonize another. It's a tool to use. It's well understood what nutrient ratios cannabis and similar crops require at various growth stages to "min/max" production.

I dunno, you might be underselling yourself. You have a really nice grow, even if you consider it simple. I'd say you're well past the point of simple growing even if you've made it easy. I do understand and respect your ethos.The world needs gardeners like you to figure out the complicated shit for simpletons like me
Some days I have enough trouble putting one foot in front of the other. There will be little to no complex thoughts for me in the near future. I'm balding enough as it is
Edit:
Thank you for the kind words. It's mostly a lot of grunt work day to day. I'm actually reducing next cycle. Tired of the work load. I want to enjoy doing it again. At this point it's just a lot of labor.
Automate! I'd go back to a closet grow if I had to mix, hand water, and other chores daily. Automation, more smoking less working.
no they don't. mine get plenty. never had a P or K deficiency. sounds like your base nutes aren't up to par.
Excessive nutrients don't "build up in plant tissues" that cause oddly burning flowersEdit:
When you tell me it doesn't matter how much P or K you feed a plant as it relates to flavor and burn qualities of the finished flowers what I hear is, "It doesn't matter what you feed your plants." It's kind of like a, "plant food is plant food perspective" that I disagree with. That's like saying a person that eats Mcdonald's 3 meals a day is just as healthy and vibrant a human being as a person that eats 3 healthy meals per day. See how silly that analogy sounds?
What you feed your plants matters. Bottom line. Don't even get me started discussing heavy metals. I'm too effing tired
Curing and drying are very important. I disagree with you regarding fertilizer as it relates to flavor and burn qualities. Maxi bloom grown flowers taste like shit. Jack's 5-12-26 using the same formula start to finish produced soil quality flavor and burn qualities. Now I don't mean to get all technical on ya here, but the proof is in the pudding. Don't go around sharing my secret with anyone
