Iron lack advice

guys thank you for feedback! DLI is 40 900 PPFD Lamp distance 55cm 26.5/27° temp center lamp some time ago I found the General Hydroponics tables🧐 they indicated higher levels of EC in hydro compared to soil cause no substrate and running water EC 3.0 maybe Is too much, but if I don't add feeds for a week I find EC 1.5 even less to keep EC 2.0 stable I should add automatic feeders 🤯 I cant do nutes everyday 😭 I wait a few days checking the EC level if it continues to drop too low I will add calmag and see how it goes! Ezzjaybruh thanks as always for valuable advice 🙇‍♂️🏻 this time, however, I'm more afraid to lower than to raise🤞 You are awesome as always buddies 💪💪💥

Also if you’re pushing 100+ DLI, as your profile pic shows.. that’s bad

I think you’re just over feeding honestly.. I’d cut down your feed by about a 1/3 You’re in a NFT/hydro set up you don’t need to be pushing 1500 PPM. I’d be more down around 800-1000 max You’re likely locking other nutes out. There’s some apparent N tox going on, you’re gonna wanna get that in check ASAP as flower development is at a crucial point and will begin ramping up on bulking. I don’t think you need to add anything, I think you need to cut a lot out as stated before - good luck. It’s a great first grow btw. Everyone seems to over fertilize their first grow.. less is more. Love seeing ppl run hydro first time around - you’ll learn a lot. I did the same thing
