Organic Grow: Week 8 into flowering. Help

Hi.

This is an organic grow, I'm about 7-9 weeks into flowering I'd say. (Haven't really been keeping count).

I applied organic bone meal flow release nutrients in the beginning and halfway through the grow when I did a transplant into a 4 gallon bucket. (plus more organic soil)

I usually have it on a 12/12 light cycle (though at times im off an hour here or an hour there, maybe 2 sometimes). 400 Watt HPS.- About a 18 inchs away. Temp in the room is anywhere from 75-85 depending if the light is on. One fan blowing good circulations on the entire plant during light hours.

Problems:

Near the top-

tips end brown, near tip yellow. some yellow, brown spots on upper leaves. curling down, also upward.

Lower -

leaves yellowing near end, some new growth ends are dark green/ others are turning yellow towards the very, very tip.

the whole plant seems to be very crumbly and break easily.


Note: I was away for 3 days and it has no lights for that amount of time. But it started exhibiting these traits before I left. I wanted to wait and see, and its definitely worse.

The hairs started turning orange about two weeks ago, but still only about 30% are a light orange color. The rest are white

PICS here - sorry they are not too good of a quality

If your plants are that far into flowering I'd say that they are just about done with its life cycle and your shouldn't really worry about it. What is the strain that'll let us know how long of the flowering period it is. I'd say looking at the pics it looks very indica dom so it should be just about done.

Also, about the 12/12. You should invest in a timer so you don't have to turn the lights on/off manually. It just makes everything so much easier and then your lights are completely controlled. Not a good idea to leave the lights off for 3 days 7-9 weeks into flowering and then turn them back on all of a sudden. This is going to stress/confuse the hell out of your plants and you could (most likely) see hermies. You are playing with their light schedule like mother nature never intended.
