What the heck is going on?!

You on good path, bluelab is my preferred choice too, but i dropped one and he started to lie, they are very sensative and need calibration every month. Have aquarium drops as extra mesure to double check are readings close after calibration. Water in 3-4 goes with 5-10 min intervals, she will soak better, amounts are ok, so all should start working.

@AsNoriu Why do you think my pH is off? I use BlueLab pen and its pretty new tbh I upgraded to it after having some sketchy from amazon which was jumping all over the pH BlueLab I found accurate and solid Anyway thought runoff of pH 6/6.2 is ok as you remember before I had lower so Im watering now with water of pH 6.5-6.7 to increase pH of soil. As to underwatering you might be correct cause its hot in tent amd I find pots always light, like no matter how much water I throw in it doesn't feel much change. I try to water my 20L pot with 3-4L at the time and have around 10-15% runoff smaller pot is 12.5L and I water her with around 2/2.5L at the time with same runoff % usually I water my plants twice a week around every 3days

are you watering enough and on time, now all pictures, like they overdried Lifting pots, the only way. Good watering regime is essential by numbers they are hungry, by ph, its still something unavailable for them, your pots ph is still wrong or meter wrong i had aquarium ph drops to check my meter always, sometime they go bad and even calibration wont sort personally think ph and watering are your two enemies at first, later you have to find good amounts and time for feeding girls I would boost them two waterings in a row with 1000ppm with high pk part and calmag added . after that will just use plain water when needed before harvesting them you are close, loosing a bit of solar panels, not the best, but not the worst scenario yet. Happy Growing !!!

@GrowingGrannie @AsNoriu where are u guys when I need you 😅

@GreenOrganicGermany Btw how can be overfed if my runoff is only 600pm at most? And on top of it I'm not feeding a lot either only every second watering with max 700pm water, where I've read at flowering you can go to 900-1050 I was kinda scared I'm under feeding 😑🤔

@GreenOrganicGermany Nitrogen overfed happened early days, hence I've cutted down micro + grow and I flushed those to ppm 300 from 1800, soil ph runoff is as today 6.1 on one plant and 6.4 on other so I thought that's decent? Ask what u need to know buddy and I will provide all details

Sie schauen überfüttert aus. Die Blätter Rollen sich ein und bilden Adlerkrallen... Durch Überschuss an Stickstoff ist möglicherweise die Aufnahme von Kalium blockiert🤔 Zudem halte ich den PH wert für Erde etwas zu hoch, ich würde versuchen ihn auf 6.2 bis 6.5 einzustellen. Also falls du, wie es aussieht auf Erde anbaust. Das ist aber höchstens eine Vermutung😅 Ohne Tagebuch, also aussagekräftige Informationen ist es nicht möglich, das Problem zu beurteilen 😅

Part2 Lamp I'm using spiderfarmer se5000 at the moment 80% 4 fans one top canopy one bottom of the tent one hitting lamp to spread heat one above lamp to cool motor. Nutes I'm advanced nutrients micro grow bloom + big buds e2nd watering terpinator + carboload + organic seaweed micro grow at 50% strenght bloom 100% but only last watering At the moment xtracalmag at 75% strenght
