Hello everyone
A majority of my plants seem to be dying yellow rust spots on the leaves dry crinkly leaves….
My pH for my run off is between six and 65 depending on the plant… My pee p.m. depending again on which plan a test is between 400 and1800…
I’m growing these in either Foxfarm ocean forest or royal gold soil…
When I feed or water IPH my water between 6.2 and 6.5…
I’m growing under LEDs and using the Foxfarm nutrients according to the schedule..
I’ll be honest I’m kind of lost my first three grows went awesome but that’s because I’ve never had any issues it was smooth sailing start to finish I am at a loss I don’t know if it’s not enough fertilizer too much fertilizer I flush the plants twice in the last two weeks with sledgehammer by Foxfarm and still no improvement…
Any help would be greatly appreciated I’d hate to see these ladies not make it to the end..

They look a little hungry to me and possibly a ca deficiency. How often do you feed/water? What’s you ppm going in? 1800 seems a little high for runoff but depends what’s going in.

I mix fox farm nutes at about half strength I also use cal-mag once a week.. I never really checked the ppm going in.. I’m still kinda new I’m very sad my first 2 grows went so well…

flushed all the nutrients out. we also dont need calmag in soil at all if using tap water.

feed her 2.5ec with runoff, drench the pots. hang back and watch until the pots are dry, then feed again 1.5-2ec throughout flower. ok to drop ec down later in flower with water only the last wet/dry cycle

when feeding in soil, always feed with runoff, it flushes out excess salts and ensures balances nutrients throughout medium.

eek.. firstly back off the light some as they are unhealthy.. and you could have some light stress going on..
flushed twice already you say?
wet/dry cycle..

Flushed 2 times in 3 weeks… I let them dry out pretty good between watering like almost drooping…. I am torn because I was going easy on the feed… I’m trying a slurry test of my soil … it’s not easy to figure out if it’s not enough or 2 much.. I feel not enough cause if the PPM of my si. Off is lower by far then what the go farm chart says is going in

My first slurry results of my soul.. this is one of the ones that isn’t looking well..

These plants look to have nutrient burn from chronic over feeding. As a point of reference, most grow charts give you the maximum amount of nutrients you should use in your water, but I have found from growing that plants will only take what they need...not what you give them. It can be deceiving when following nutrient charts because things look good for a while after a few feedings and then after a few weeks when the roots are growing into the soil, the leaf tips start to burn, then along the leaves edges, until eventually the leaves turn yellow, dry, curl up and die due to a high concentration of salts in your soil. One thing I have learned over the years is that it is better to recover from a lack of nutrients than it is to recover from chronic over feeding 😉 However, I have also found that some strains are more resilient than others, and it can make identifying the problem harder when growing more than one strain on the same nutrient mix. As a rule of thumb, in soil anything you do today will take close to a week to see any results (sooner in hydro).

Here is an article which might help you, but understand that a plant never really recovers well after identifying it to be overfeeding due to the time it will take versus the plants genetic life cycle.
