Leaves problem

Hey man. So tbh with you. This 1 has me stumped. I don't think it's mag though. In week 11 I can see your plant is clawing like mad. And I see you are using 1 core nutrient. If I had to give an answer I'd say you are experiencing a multi def thing going on there all stemming from nutrient lock. As that nutrient is locked out and it's only 1 core nutrient you plant is finding it hard to take up stuff and yeah it's just in limbo. Tbh with you. I've never seen growth go from the way it was week 11 to that. Which by looking is a few weeks apart from the healthy (but clawing) looking plant. You can see it clawing and if you didn't fix the problem from there your plant was throw into nute lock and without seeing past pics and how she came about like that. All I can say is if you have an all in 1 nutrient and it's not working but does for others you are in nutrient lock. I'm sorry there's not much more to it. But I would consider restarting her diet and add some a calmag after you cut your feed for a few days and give water. And restart on half of what you are giving her now. And I'd cut the silica now it's done its job. Let your plant focus on the kick start. I don't think she's near her end of life to look like that. But yeah. Leave her for a few days on what you have given and half it on the restart. Good luck.
