What's wrong with my plants?

So I'm using a MH HID 1000w light with 8 sour D's underneath in fox farm ocean forest soil and feeding fox farm nuts according to the nute schedule which is probably my issue cause they looked nice green and healthy just a week or two ago and before when I was barely giving them any nuts. A few things. I recently made a few cuts for clones from all of them. They have an early case of PM and I've treated with neem oil twice. I'll be treating with eagle 20 in just a few days/ bleaching out my grow tent but what's up with these deficiencies?!?!? It looks much lighter l green, the new growth. And the rust? Whyyyyy

Ok so I just got a huge lesson in soils and fox farm happy frog and ocean forest. I used frog then forest and used the nute schedule from fox farm (ff) After 2 runs with this schedule I got the same result twice. Both times I Nuked the hell out of my plants with waaaaay to much nutes. I am a novice but live in Mich and have lots of access to good growers. My Yoda asked me "did your plants start amazing then burn up , get tip burns, start to herm , smells like hay, and no real crystals ? " I'm like dude that's my 2 runs to a tee!!!!! and I run 2 p900 platinum leds in a 10x10 gorilla tent in a super clean I mean clean space. Ruining my fans my fresh filtered air coming into the tent and venting out to the outside thru my charcoal filters. I did everything right besides talking to experienced growers. Yoda told me " the ocean forest has so many built in nutes that I can go 4 to 6 weeks in veg with just water ! I'm like what,!????? No veg nutes ?? He's like fuck no kid, when ya flip the lights to 12/12 then use " heavy 16"once a week in flower w some molasses and just test the runoff. ". I knew i was doing something wrong but what ff won't tell ya is that ya don't need nutes w that soil. Yoda said in the flower the plants will then tell me what they need. ( cal meg , fire , prime, or flush finish). So all in all DONT NUTE WHENUSING OCEAN in veg. Then add nutes in flower. And don't use ff nutes. Go get heavy 16 bud A and B. Hope this helped. Wish I would have googled ocean farm and over nuting along time ago !! Happy growing.

my bet is its either iron or zinc deficiency... maybe even a combo of a few micros nute def

check your soil ph make sure its not up to high

if you want a quick fix .. foliar feed resolves the issue quick and the old growth will mostly green up

zinc edta... if its zinc... or a balanced micro nutrient blend

I had a similar looking problem. I was using fox farm ocean forest and fox farm nutrients. I had a small amount of burning and I immediately flushed them. Also I added a microbe additive and stopped feeding all together. I used only pH water and a touch of molasses to feed the good bacteria. The fox farm soil is so rich you do more harm adding fertilizer. Keep the water clean keep a close eye on it. Once it is under control give it a few weeks before you feed them and only do it at half strength. Hope this helps.

another Fox Farm snafu day after day around here, so sad

Hey! looks like there has already been some pretty helpful replies to your thread. One bit I would just like to add is maybe invest in a RO system for water filtration if you are going to be using the fox farm mediums which require mostly just good clean ph'd water. I also would like to recommend more beneficial bacteria and creating a live soil. Giving your roots especially and your plant as a whole what it needs to survive.

Definitely a deficiency of some sort..

iron, zinc and phosphorus compete with each other

in most cases those symptoms are from ph rising out of range in the medium/soil which can happen even if your feeding with nutes that are in proper ph range

so if your soil ph has risen out of proper range then a good flush with some low ph water (5.8 to 6.0) todrop the medium/soil ph and then back to nutes as normal

the other option is you've got a nutrient imbalance,
either;
to much iron locking out zinc or not enough iron
to much zinc locking out iron or not enough zinc
to much phosphorus

if you want to provide me with what product your using/ the amount of MLs per gallon your dosing

and the guaranteed analysis info on each of the products your using... I can tell you with better certainty which is more likely
