Ive been growing in dwc and it seems that everytime i clean my res while in the flower stage my plants go into shock. The leaves start drooping the next day and never recover. I thought that it might be from transplanting during the flower stage and the plant being sensitive, but upon further reading people clean their res often while in flower. HEELLPPP. ive had 5 or more plants that were half way through flower die bc of this. Can anyone give me some pointers???
