Nutrient Problems, high EC, but signs of deficit

Hi, from my perspective, the runoff values for EC and pH seem completely fine. If you're feeding the plant with an EC of 3.00 and getting a runoff of 4, that's normal based on my experience. However, I have the feeling that your plant is missing something. It looks very pale, which could be a sign of nitrogen deficiency. The necrotic spots might be caused by over-fertilization, but the rest doesn’t quite add up. The leaves are slightly curling downward, which indicates improper water management. Please increase the CalMag dosage to 1.0 - 1.2 ml per liter. The BioBizz Grow also seems too low—please increase the dosage to 1.0 - 1.5 ml per liter. From my experience, it’s quite difficult to over-fertilize when growing in soil. I suspect your plant is lacking CalMag, nitrogen, and potassium. Please increase the Bio Bloom dosage to 3.0 ml per liter. Good Luck! Feel free to Ask!

soil? Soil EC can run high and not be a problem. This looks more like deficiency than toxicity or some unusually limited lockout. pale all over, what looks like calcium deficiency... maybe your p/k are sky high locking things out? People tend to follow bro science and just blast the platns with "more" without knowing how much they already add, so if that sounds familiar backtrack on that. the skinny new leaves and chlorosis lines up with too much p/k. ratio of nutes, watering habits etc... this wasn't caused in 1 night of behaviour or 1 irrigation. this is month-long bad chocies or more.

Hi, it looks like you have a nutrient lockout. A high EC value can actually lead to a nutrient lockout in cannabis cultivation. If this value is too high, it can cause salt buildup, which hinders nutrient uptake by the roots. You need to flush your soil a few times with pH-adjusted water. Do this about 3 times and wait until the soil is dry between flushes. Check if the top 4 cm of your soil is dry. Or you can use a stick like a toothpick in the soil; if it comes out dry, you can flush again.

HI bud. This looks like a case of salts/minerals buildup in the soil. Often due to bad watering habits. If the soil does not get a proper dry/wet phase, the salts and minerals can continuously build up. That could give you a high EC value and yet measure normal on the ph scale. An EC between 1.5 and 2 is usually what one would aim for. If I'm correct, letting your soil dry properly (first 2-3cm) then only applying water ph'd to 6.5 (no feed) until a runoff of 10-20% should wash the build up away. Be sure to keep an eye on the ph and EC vales of the runoff. It will take a couple of waterings probably so don't be in any rush. When the EC and PH are both where they need to be, you can start feeding again. Just don't forget to maintain a proper dry/wet phase, and don't feed your plant every watering unless she absolutely needs it. Hope this helps, even just a little.
