One sign of lack of nutrients is the lower leaves turning yellow and falling off. The plant is using all the available nutrients in growing the flowers and starves the lower leaves so they die.
The lower leaves may also turn yellow and die the last 2-3 weeks before harvest. This is normal (See some of the plants in the August BOM contest).
At 60 days in 50% coco it would be hard to tell if this was a normal process for your plants or is it due to lack of nutrients?

The above article says half strength every 2nd or 3rd watering.
How much of the trio are you feeding in how many days? How often are you watering?
How about the pH of the water and the soil?
Could you post a photo or two of the plants?
You could give them a one time feeding of full strength and see what happens. If it is too much then you could get nutrient burn and the leaves turning yellow on the tips.

I feed them 1/4 strength every other feeding.give them rain water n don't test pH...been thinking that's my problem newbie with little supplies.but everything is fine till flower....so I wasg thinkjng it was the way I'm feeding them. maybe starting flower nutes at week 4 is to soon n plant is dying.....
I guess I should be in infirmary sec ,my first cry for help new to site.a bit confused.

I am betting the molasses is either throwing the PH off or the Epsom salt is locking out your nutes. I would run strait happy frog with the trio pack and PH your feedings and get that down before you start adding extra things like molasses and implement things like this one at a time through out grows so if you have a problem you know what jacked up your grow.

Temps in 80s should be fine as long as youve got some air movement. Do you flush before switch to bloom nutes? If not I would suggest trying that. Flush with at least 2x the volume of your pot, so 4 gallons of PH'd water, best not to dump it through all at once, do about 1 gallon at a time, every 30 minutes or so.
