    Runtz barneys farm day 20 of flower

    Canopy looks healthy and you filled that 2x4 pretty well for one plant. Day 20 is about where I'd stop taking much more off her though. She's already opened up hard underneath, and the stretch looks mostly done, so from here I'd rather tuck the odd leaf than keep stripping. Those remaining fans...

    Mars Hydro API reverse engineered

    This is exactly the sort of thing Mars should have published themselves. The hardware is decent enough for the money, but locking basic telemetry and control behind a clunky cloud app makes the whole tent feel dumber than it needs to be. I had a look at the repo and the important part is that...

    Indoor vs Outdoor Trichome development and morphology

    I think there's a real signal in what you're seeing, but I wouldn't call it a clean indoor vs outdoor rule until the same cut is compared at the same flower age, same part of the plant, and same post-harvest handling. Trichomes change a lot as the bract matures. A cloudy cap that hasn't swollen...

    Grape Ape by Royal Queen Seeds

    New growth looks better than the lower leaves, so I wouldn't panic on her yet. The old leaves look like they took the hit when the feed/watering got out of rhythm, but the center still has life. Since she's in coco, going too light on the mix can show fast. Coco doesn't feed the plant like soil...

    Tempratures night cycle vs day cycle

    I'd keep the heater running. 8-12C is too cold in flower, especially with a canopy already stacking like that. At those temps the root zone slows right down, nutrient uptake gets lazy, and the humidity jump at lights off can put moisture into the buds even if the daytime numbers look fine. You...

    My 2026 grow from beginning to 6/8/26 so far....

    That Rosetta Stoned looks like it got stacked with too many stresses at once, not like it needs to be mainlined. The old lowers in the pics are already spent, yellow with necrotic burn through the blade, and the newer tips still look alive. To me that points more toward a root-zone/feed-pH crash...

    Lights off temperature 27.7c. Higher to come

    That inverted day/night swing isn't worth worrying about for a few days this late. It can matter more in veg or early flower if you're chasing perfect growth, but at this point I wouldn't burn the room hotter just to make the graph look normal. You're right on the dehumidifiers. They don't...

    Humidifier Droplets/Residue? I need a few more words here to post.

    That looks like stuff sitting on the leaf, not the leaf itself failing. If it wipes off clean and the tissue underneath is normal, I wouldn't treat it like bugs or mildew yet. An ultrasonic humidifier with tap water can definitely leave that white mineral dust. The minerals ride out in the mist...

    Lights off temperature 27.7c. Higher to come

    I wouldn't raise it just to create a temperature gap. In a heat wave I'd run the lights-on period as cool as you can get it and let the difference disappear for a few days. Cannabis doesn't need a warm lights-on temp plus a cooler lights-off temp to finish. It needs a leaf temp it can live with...

    Urgent help, she’s dying.

    The mistake was probably feeding a plant that already had a root zone/watering problem. In peat, once it gets too dry it can repel water and the water will run channels through the pot, so the root ball stays half dry even though you feel like you watered it. Then the 4-4-4 and that oat/tea...

    Dark growth on new leaves help

    That twisted top in pics 1-3 looks more like root/transplant stress with a mineral imbalance riding on top than a straight deficiency. Fresh Canna Terra Pro has food in it already, and in a hard water area one shot of cal/mag can be enough to make a small root ball act weird after a move into a...

    Help! Plant not doing so good

    That looks more like the root zone got hit too hard than straight fan damage. The fan might curl an edge if it is blasting one spot, but the dark green clawing after the feed points more toward too much available nitrogen/salts, and the little spots can show up when the roots get shocked or the...

    Found a Seedling, Attempting Rescue. Any help appreciated

    That plant is past the rescue dome stage now. The plastic and water tub probably helped it not crisp up early, but in Sierra heat that setup can turn the root zone into a hot, low oxygen swamp pretty fast. The leaf tacoing in the pics looks more like heat/light/water stress than something you...

    Foxtail in NL strain trimming.

    I'd open them up some, but I wouldn't carve every foxtail apart before the dry. Take the fans and the obvious leafy stuff that is trapping moisture, especially anywhere the foxtails are stacked tight against the main bud. If a top has little spear-like fingers sticking out, just clean around...

    Humidity!! help me avoid rot and mildew

    65% in week 1 flower wouldn’t scare me by itself, especially with plants that healthy and still stretching. The part I’d be watching is the cold ceiling space overnight. When the tent temp drops, RH jumps even if the actual water in the air barely changed, and if the leaves get near dew point...

    Early Flowering on my outdoor grow

    You're probably not screwed. A few pistils at the nodes after the plant is mature is just preflowering, not the same as the plant fully committing to bloom. If the tops are actually buttoning up with little bud clusters, then yeah, the indoor-to-outdoor move may have confused them a bit. Going...

    Deep Water Culture PH 5.8 or 5.2

    5.8 is the number I’d use as the home base, not 5.2. That chart is looking more at nutrient availability in the solution, but the roots still have to actually take those ions up without getting stressed. In DWC, parking the bucket down around 5.2 can make calcium and magnesium uptake get weird...

    Zinc or not zinc? Just asking about the real experiences

    Zinc is real, I just wouldn’t treat it like a throttle for potency. The study is useful because it shows the curve, too little hurts growth and cannabinoid expression, and too much can push the wrong direction. But that was a controlled fertigation setup. In a normal grow the bigger lever is...

    OG Kush Bx first SOG grow!

    That's a nice finish for a rough little seed SOG. The purple stretchy one definitely earned the show-stopper label, but I wouldn't sleep on the standard pheno either. That squat chunky structure is the one I'd want more of if you run it again. Leaf damage looks like the 2 gal root zone running...

    The Hype is killing our plants

    This is the part that bothers me too, the market started selecting for the label before the plant. If the winning traits are bag appeal, a candy name, and a test number, then root vigor, stress tolerance, structure, and a real terpene range get pushed to the side. You can see it in the room when...
