Issue getting progressively worse

This plant was one of the healthiest at one point, then took a turn for... I don't even know. Never seen a plant do this. The soil (ffhf and ffof + 33% perlite) is being used for multiple plants, and this is the only one showing this sign. When organic nutes ran out i started using Mega Crop (2g per gallon) 1 part, watering in at 6.5.

Any help would be apprexiated!

If you are doing the same thing to all the plants of similar strains and only one is showing symptoms, about the only thing you can do is see if it gets better or if other plants start developing the same issue.
Cal-mag seems to be a common cure for many definite nutrient issues. As opposed to pH, EC, soil moisture...
 
I've always watered in at about 6.5. Today was a water day. I watered in at 6.7, and runoff came out at 5.9. I will continue to water in with a higher PH. I thought about dolomite, but I don't know if that will help buffer PH by only being top dressed; I do know it will possibly turn the top of the soil into a brick from experience.

I've had mag def before with fox farms, so I usually add epsom salt at .25-.5g per gallon of water, which has helped for the most part. This still seems a little different as the mag def I've always experienced went brown after greening the veins of the leaves. This lime green with lime green sprinkles is reacting different. Either way, I added some calmag plus at a low dosage just incase, and cut out the epsom salt.

I'm still trying one thing at a time, as recommended by most, I figure as the only change is calmag. Increased water PH is a given.

Thanks everyone. I will update the post, even if it is to say I cut down the plant (flipped to flower a week ago -- it's on a timer to see if it recovers at all and is worth the eight weeks).
 
I had the same problem my first grow with Fox Farm. Both plants did it. Switched soils and no problems.
 
This is my first time using FFHF and I have fought cal-mag def for a month now. Went real smooth for 60 days and the nutes got sucked up. Been using cal-mag 1tsp per gallon phed at 6.5 with Azomite and its coming back greem. Most of the leaves that yellowed out fell off got cut. Good soil but sure does cost.
 
I was going to go with foxfarm for my grows and when I called my landscaping buddy to ask if he could order it he gave me a lead on a local compost facility that made super soil. Cheaper than FF and man I am getting results. More of a local thing so it won't help many but the place is called Tilth soils (Cleveland, Ohio). Seems like a bunch of young hippies making awesome soil. I reused the 1st grows dirt to finish off some small plants and it had enough soft nutrients to where they finished and didn't become deficient. I'm cheap and I've spent about 400$ with them so far on about 4 grows worth of soil.
 
Yeap. I used them and after like 1 weeks flowering had major deficiencies. Chasing down why. Well, Fox Farms Happy Frog loses all nutes after like 6 weeks. Also, it does not drain well. Easy to over water. Becomes compact after time. I use DNC water only. Put a 5 gallon of DNC up against a 5 gallon of Fox Farm in fabric pots, it let me know which one drains better. Fox Farm soil, in my opinion, is WAY overrated. I get a bag of DNC for $25 where I live. Delivered. Zero problems all the way through flowering. Fox Farm Happy Frog, dude, your chasing. Dump that garbage.
 
For pH issues I would do a slurry test to test what the rhizosphere/soil pH is. This should give you a better idea of what your true soil pH is rather than measuring the runoff. Not that runoff is bad but slurry is more accurate.


How to Test Directly in Soil

Using an auger or ruler, first put a hole down into the soil. The hole needs to be the same depth each time you test to avoid pH discrepancies.

Add some distilled or deionized water to the hole; the soil should be damp but not saturated with water.

Insert your testing instrument into the hole, and allow for the reading to develop or stabilize.
 
And I'm not plugging a company here. As you can see I've done both. Happy Frog red, sticks and chunks of mulch, very dense. DNC very black, loose, no mulch. Happy Frog in my opinion is nothing more than glorified mulch. Way too dense for MJ.

I grew in coco before so deficiencies are easy to spot and correct. Follow a schedule and alls well from my small indoor growing experience. I came a bit confused as what to do when it came to a soil that already had nutes in. It seemed very abrupt when the nutes were gone and the rebound took more time in soil. Now three + months in I'm on schedule for mid flower using organic nutes FFHF for amendments for FFHF soil.$$. I noticed the compaction before i top dressed and slowed the water a bit before . I dont drain like coco for sure.
 
I've found Roots Original to be very stable. Every bag I've bought has pHed within range.

Plants under LED tend to need more cal/mag. Add in coco and the issue gets worse.
 
I didn't add any coco and was able to stabilize the nutrients in the FFHF soil. I like coco but it takes more vigilance and im a lazy hippie.
