too much nitrogen; classical claw. I suggest backing off the nutes, or changing to low N higher K&P (like Maxibloom)
lots of other plants have red stems that could be stalled sap being too cold check your temps too, or miss a couple of feeds good luck
i would suggest testing your soil runoff ppms and ph you have a lot going on including burnt tips, clawing , red stems and yellow fade maybe your soil is too hot or are you in coco?
