Defeciency help - cant pin it down

Need some RIU input. Cant quite pin this one down.

Basic Rundown:

Age: dont realfly know. Maybe 5
weeks into flip.

Light: 450w LED (solo :/)

Medium : FFOF

Nutes: main nutes im trying Tippin
Roots bud booster.
Supplement with, Blackstrap
Epsom, and a Bonide rot stop
Liquid calcium.

Environment: Grow box, humidity
45%-60%, Temps 63-70. PH
runoff at 6.6.

Plants looking allright. Too many for light. Im rotating plants but its allready kiling yeild outcome. I can add another in a week or two but will be too late. Anyways..
They show slight nute burn from last feeding, and had some light burn here and there. Been having deep rust covered spots on lower , larger fan leaves. Ny first thought was Calcium right away so I added the rot stop luquid calcium. However two days later the
Problem is still spreading. Mainly
On older lower fan leaves but some newer fan leaves also. Its not consistant. Rot stop being a liquid calcium I figure its pretty fast acting. I use tap water too not R/O. I have always had cal-mag issues with foxfarm though. Could this, be iron, or another issue?





Heres what starting to hsppen..


Thanks for checking this out and any and all input would be great!

That's more likely a magnesium issue if starting at bottom of plant, calcium shows up on newer growth. So the question becomes why a magnesium issue if you are supplementing with epsom. Answer is often nutrient antagonism so you have to see what else you may be overfeeding, reference Mulder's chart. High potassium levels can lock out magnesium, so maybe an issue related to the molasses?

Yeah, that was along the lines of what im thinking. Maybe caused a lockout somewhere. Its tough to figure out lol.

Maybe best to flush, and start again

Have you checked for mites?

Yes. Checked mites too!

Have you checked the ph of your soil? if your runoff is that high your soil may be to hot thus causing lockout of micro nutrients. I would check that first before you flush everything out. Soil you need to be 6.8 to 7 is perfect.

I try to keep PH at 6.8 usually for soil. But i stay away from over 7 and under 6.5 hopefully. Soil rigjt now is sitting at 6.9. Last watering i think i was a bit high to start. Old pen getting less accurate I imagine. Honestly I think im stuck with a micro nute problem. Its not quite calcium def looking nor Magnesium. More leaning towards iron I beleive. Will check them when they wake up. Not my main grow so set up sucks. I hate flushing these. I didnt set up a tray system so its literally take the plants to the tub set up. Ughhh lmao. But it works . Im not fimliar with the Tippin Roots nutes. I used 1/4 strength so shouldnt be excess of pk. I have FF soil trio but I dont like adding that much N in bloom phase.

Well why i grow 100% organic never have to worry about if your adding too much of something and never have to worry about flushing out nutes just water them and talk to them occasionally give them a little hair cut, only prob with organics is it does attract a few more bugs but nothing a little neem wont solve, here are my girls they are 58 days into veg flipped to 12/12 tomorrow

Good looking plants, you in 10 gallons there? Whats the flavor of the day?
