What kind of setup are you running? Have you tried just feeding her some ph'd and light nute water? May just be underwater. If her situation doesn't change after that I would get some CalMag to add to your feeding. Best of luck .
I just got some today. When I mixed the soil I loaded the soil with enough to feed it for a while. At least I thought so. Liquid fertilizer Foxfarm Grow Big, Tiger Bloom, and Liquid Plant food Big Bloom. I was going to feed with the Grow Big but thought I would check with some more experienced people.
Can't personally say I have used any of those specific nutrients, or tried preloading soil with it. I've found my plants love light nutes about a week in then slowly increasing, But when I didn't use nutes my plants almost always reacted how yours are now, (especially ones that I topped because they need more to process that extra growth). I think you will solve your problems just by adding a regular nutrients feeding schedule
