Something wrong

I've posted on this before. Don't have any pics. Growing under CFL's in soil.Plants have been budding for quite some time and the buds would be huge but they are not filling up.Continues to grow and more hairs but no meat.Leaves have been turning yellow starting at tips and drying begins at the same time.Whole plants feel dry and crumbly.Flushed with rainwater and watering with plain rainwater as well.Had been feeding half strength superbloom prior.Don't know what to do.Any help would be appreciated.Thanks

Put up a picture.

Sidenote: Depending on the medium you are growing in, flushing, with rainwater, or Holy Water, can starve your MJ plant badly.

What kind of temps, how many times a week do you feed AND WHAT \kind OF NUTRIENTS ALSO WHAT STAGE OF GROWTH???

75 80* I was feeding once a week with superbloom half strength.Been in flowering stage for 2.5 months. Has been in stressed state for 1.5 months
