Ready to harvest? pics

Do you think these are ready for harvest? If not, how long would you wait? They have been flowering for a long time (almost 4 months) but the buds only started to fill out about a month ago when I switched the funky HPS bulb that came with a budget system from htgsupply with a Son Agro bulb. TIA

Have you studied the trichs? You are one patient person. 4 months is a lot of folks whole grow . . . sure hope the trichs aren't all amber, unless you wanna couch it. Your buds look great, Salo99.
I can almost smell them thru my monitor! Yum.

gi damn man u been budding for quite a while that how long my plants are from start to finish hope u like ur budas and definantly harvest man

Nice job.. Enjoy

If 2/3 or 3/4 of the hairs have turned brown or red.

If you look at the trichomes with a magnifying glass and they appear to be amber colored. Clear means that they haven't developed fully and brown means that they are overdeveloped and losing THC content.

Ok, thanks guys. The reason I waited so long is the buds were tiny and I couldn't find the reason until I got the Son Agro bulb and realized it was the crummy HPS bulb from htgsupply. So in a sense they've only been flowering under good conditions for a month. The buds were practically nonexistant for the first few months.
