hey Dandamans, this doesnt look fantastic, but it could be one of two things scenarios : lockout/deficiency, or aging/flowering - the lower leaves could be nothing and just falling off after being canabalised for nitrogen as part of being old or the soil might be lacking in nitrogen. The top leaves could be turning colorful because of a lack of K potassium or it could be lock out from the nutrients that went too far. I can't really tell you more than this based on the progression I'm seeing. I hope you're not feeding every watering at least , because that would explain the first scenario. Hope this helps ! 🚀

I don't see any information related to feeding strength, so over feeding is very likely. That the leaves affected are the newer / upper ones, means it is a immobile element, which means it is not nitrogen, potassium or phosphorous deficiency. It looks like a severe case of calcium deficiency, most likely because of nutrient lockout due excess feeding. There are burnt and curled leaf tips, which supports the thesis of over lockout due overfeeding. Keep in mind that both excess P and / or K locks out calcium and magnesium. Get a EC / PPM meter and check your feedings. In the meantime I would stop using that Mammoth P and give the plant water only.

Hey there! So it tough to tell just from the pics But the top leaves on the Berry looks to be a Potassium deficiency. The thing is though you have to find out why it is having that problem is it not enough nutrients or is it getting to many nutes or bad pH range in the soil can cause a lock out and no mater how much you give them they won't uptake it. So first off if you are feeding them every watering. You may want to try a feed-water-water-feed schedule that will give the plants time to take the nutes in. You should also check your runoff pH to make sure that is in a good range If all these thing are good then try adding a little more K into the mix Good luck Happy Growing!🙏
