Is this a Potassium deficiency or lockout issue? Symptoms show up after 2 weeks in flowering. No root rot. Poor yields and turn hermies/bananas a lot

Looks like nutrient burn. Even if you are feeding low amounts the proper amount of water that guys flushed out every time is very important. You need to mix enough to flush out roughly 10-20% of the water though the bottom of the pot. This will clear out any salt (nutrient) buildup in the soil. I suggest you run about 2-3 gallons of pHed water though your soil to flush any build up that may be occurring in your soil. It’s really easy to build up salts in the soil if you do not properly water it with 10-20% run off every time. I hope this helps.

it looks like a nute burn. when i started growing i got this adwice.... if the tips are curled its usually a sign of wrong amount of fertilizers. if they are curling upwards its a sign of burn. if they are curling downwards its a sign of deficiency. i have experienced something similar which was a slight nuteburn mixed with continiously over watering the plants for 3-4 weeks.. make sure you let your roots dry between each watering. Good luck mate.

Looks like a lot of nute burn. Which I think is a salt build up. You are not providing enough water or solution at feeding to rinse out old nutes. So it's just building up and causing lots of ph issues and burns. Brown tied curling up an in is nute burn.

2.2ml /L of such a potent nutrient needs to be given to a NO nutrient soil.. Ur using promix. Idk if bio vegan holds an EC but its clear its causing PH issues with ur soil.. Also. Promix and orgainc nutrients don't need ph'in as its an organic process so I'm definitely going with cla

Looks like a bad clash of nutrients. When giving give a few days apart. ..not all together if you're doing this these nutrients used with other products need time apart in the pot or u get adverse reactions. Also. Soil ph should be 6.3-_6.8/7ph. But lower than 6.3 in soil is not good.

Sounds
