LIVE SOIL. too much nutes or not enough?
I think its toooo much nutrients from the live soil, and cold/dry conditions for too long. but someone else said it's lacking nutes? (I was sick, and they were a bit neglected for a bit.. ) using live soil, like I said more info in my diary thanks so much for any input 😊

Nitrogen deficiency, light burn? Calcium?? Which deficiency?
Growing organically with happy frog mixed with a super soil concentrate. I water them with spring bottle water, ph at 7.7. Recharge every 10 days. Top dress 2-2-2 dry amendments. No clue what’s going on with this, thought it needed nitrogen. Top dress. Some new growth looks good

Runoffs are significantly below inputs-Do I have a problem?
Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Halb gelb, halb grün
Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Rust spots on leaves, second grow and need some confirmation.
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

Troubled seedlings
Is this nutrient burn? Had what looked like a lack of nitrogen early on, lowest leaves were healthy then quickly went yellow and worked up. Now have fed nutes at 0.7EC (tap water left for 24hrs to 0.28EC) so fed under 0.5. Bio-grow 0.5ml/l bio-heaven 1ml calmag 0.25. Thanks

Hi, 2 of 8 got yellow/brown spots on lower leaves. I've watered them once a week and add calmag, pH=6,2 following b.a.c. instructions. Last watering, i forgot calmag so I did a second watering 5 days later with calmag. What could be the problem ?

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.
