The past 2 weeks been noticing some dead spots(necrosis) brown spots/rust spots, and one single leaf on one plant has purplish blotches. Is affecting a few plants. I'm thinking some kind of nite burn or defiency. Can anyone please help me! Here's a quick rundown of my nutes soil and shit, I'm useing all organic:
Humboldt nutrients grow natural-bloom natural-deuce deuce and molasses. I'm also growing in FFOF. I been feeding my plants every watering the recommended dosage, not anything crazy or nothing, as of last feeding(per gallon) 5ml grow 5ml bloom 1.25ml deuce deuce and 15ml molasses. I'm also 17 days into bloom. Can anyone please help me try to identify this shit and help me correct it, thanks!0

Just from a glance looks to me like n problems from my own personal experiences anytime u c the leaf tips turning any direction other than straight out the majority of the time its n problems
Id start cuttin back on grow nutes instead of 5ml try 3ml and if problems persist then drop it more usually by day 20 of flower I've completely done away with grow nutes until last 3 wks of flower to give an extra lil shot of n to finish strong but hope this helps good growin guy

Word. I plan on feeding straight water next feed. Maybe straight feeding nutes every other watering, or maybe at a diminished dosage.
Anyone else feed every watering

looks like low ph could be locking out Ca Mg. Do you use tap water or filtered? also that ducedeuce in my opinion could be doing more harm than good. Huge levels of K dont mean huge buds.
also molasses can be counterproductive unless your making a AACT. can stop nutirent uptake if not being eaten by microbial life. also check for pest. something looks like its been having dinner on pic number 2 in particular.

1st step: check your runnoff for ph and tds. ffof can swing pretty low espesially with feeding every time you water.

nothing you can come back from.!

Do you mean nothing I CAN'T come back from?Jeez I really hope I can come back from it! What I'm going to do is give a good straight water feed next watering and after that feed every other watering. Also cut down on the mOlasses. But I only fed them deuce deuce once and just started feeding mOlasses recently too, and some of these symptoms were their before I started. Also the water I have is well water, and IMO it has alway been on point with ph ect.. Not sure about the pest, if their there then I never seen them, and I'm in my fargen pretty much everyday looking at them super close.
Do you think by cutting down on the nutes, as I mentioned, will correct this problem/ stop it from getting worse and/or spreading? This is something I can deff come back from right? Most if the. Foliage on my plants are mint and looking nice, but just some places show these symptoms

Yeah I was up all night def. meant all good. You CAN come back. In fact your not gone yet. If its growing good and not showing new problems keep doing what you doing. Well cut down on molasses for sure.
