I started my first grow on 2/25 and put my 2 white widow fems on bloom mode last Friday. The plants did real well until about 2 weeks ago and then they started losing quit a few leaves and don't look as healthy as I think they should right now. My question is should the plants lose a lot of foilage when they mature? also had to tie off one plant because of the weight and I was afraid it was going to fall over. I am growing these in dwc and the big one is over 4 feet tall and the runt, which started off strong is 3 feet. The big plant drinks about a gallon of water a day and the runt about a half gallon. Pruning has got me confused with losing the leaves as they are doing. I have been changing the nutrients every 2 weeks, but because of the size of the big plant I am afraid to lift it up by the net pot to change it anymore. I hope I have made this clear to you guys that are experienced in growing. I just want to do what is best as for as pruning, topping and making some healthy plants. Any advice would be appreciated. I'll send some pics next week if I can figure out how to upload them.
