Nutrient lock out?

[Marine2805]

New grower here. I believe I had nutrient lockout and I unfortunately left it too long without flushing and had to cut away alot of the fan leaves, probably too many. I also had topped it. Will this start to grow again or is it a lost cause at this point? Got a little too happy with the nutrients.

You definitely have issue(s). Looks to be a non mobile nutrient. What are you growing in, what are you feeding? What’s your lighting? How often are you watering? Those those plants can recover.

Growing in DWC, using VIVOSUN smart grow system with the 100w LED grow light. All pics are the same plant from this month. Feeding them VIVOSUN nutrient base A & B. I havent been completely replacing the water, just adding more when it’s getting low. Also put in some liquid kelp extract.

i was going to say iron def, but im not sure, that's real pale, not seen that b4 sorry. i would try washing out your dwc bucket and adding new nutes and see if it changes colour

I was leaning towards iron or mg. With 100 watts it’s not light burn. It could have to with not cleaning the tank and just adding more nutes, maybe a chemical reaction locking out iron. I did see on the vivosun website it says not to add A and B together in concentrated form or lockout can occur.

Describe in detail exactly how you're preparing your bucket with those nutes. Give pH and EC numbers, as well. Looks like a very advanced iron deficiency.
