Thanks man, I have Fim'd and Topped in my previous grows and I have not used any nutrients yet just been waterin with water and a little molasass here and there, I do have a full thing of all purpose mircle grow plant food that you mix in with a gallon of water is it time to start useing that?

hmmm ive never used miracle grow, as this site advised me not to lol. As long as you've got a high nitrogen content versus phosphorous and potassium. the "N-P-K" number should be like.. 20-5-20 (just an example). Fox Farms sells a product called Gro big, and it seems to make my plants healthy everytime, but I'd imagine an all purpose one would be find. do you what the N-P-K content is?

I like how you used that soup cup for a pot......nice

When temps go to low the plants dont up take the nuets mabe this could be your problem. I had them same problem with the cold and my ladies were showing a mag def. good luck mate
