Pineapple Expression

PE1 and PE2 are flowering and stretching heavily. PE1 has a few wilted leaves, wich i think is due to overwatering, or maybe some sort of root issue. However, the soil doesn't feel muddy or anything at touch; actually it feels quite normal. PE3 began to show some magnesium/iron deficiency, and also seems to be stuck in vegetative; no pystils at all. I transplanted it to 18 liter pot; just to avoid any risk of root-bound. In addition, the main shoot has been trimmed, and the secondary shoots have stretched in two days, so i guess the transplant went ok. PE3 will be sent to a dark room for a couple of days, to see if flowering triggers. Hope it's not a male.
