It’s the performance pack. I only follow the green

You should visit their website and look at the other schedules for their trio. Review the options for light/medium/heavy feeding. I'm doing autos so I'm doing Trio with the lightest schedule and I'm backing that off a good bit on top of it (was doing half now I'm doing 3/4ths on the 7th week of flower.

Use some cal magic

It's a Magnesium issue

But whai. We don't know that its calcium deficient. And that leaf doesn't suggest that. Throwing more junk at it without knowing may make things even worse.

Something has stopped/locked out uptake for Mag and K. It could be pH or it could another element throwing off the cation exchange.

Lower the pH. I know its FF "soil" but if its depleted and if you've moved on to bottles/salts then you need to get the pH in range for better uptake. If you've been using Flora from the beginning you might have salt buildup.

If it were me, I'd only used the base and nothing else. Those charts are simply a rough guide. There are a LOT of variables a grower needs to take into consideration before adding supplements.

All you need is the grow, micro, and bloom.

1000 true watts? It actually uses 1000 watts? Tell us about your light.
