Getting concerned about lack of odor and stickyness

I am entering 5th week of flowering today and my 2 plants are looking good , they are healthy and robust and have buds all over them. I have 2 strains , one is Orange Kush and the other is Durban Poison .

I am concerned because there is absolutely no odor or smell coming from my grow room . This is my first hydro grow , I have always grown in soil before and everytime I have ever grown I usually have a very powerful odor coming from my grow room , so much so that I can smell it all throughout the house. and even down the street if I have a door or window open.

This time there is no odor and the when I touch the plants stems and rub them I can get a faint smell on my fingers but it is not very strong , also they do not feel that sticky to the touch. I have looked at them with a jewelers loop and they do appear to have trichome development but it's not frosty looking as it should be so I think I have a trichom problem and I don't know what it is. I have read online that man say it could be genetics but I have 2 different strains , one being a Sativa and the other being an Indica dominant so I don't think it's genetics . I get the clones from a reputable clone supply company in Seattle and never had a problem with their genetics before.

My grow room temps range from 55 degrees during dark and around 70 degrees during Light Cycle. Is it possible that it's not warm enough in my grow room? I can't think of what is going on but I should have more stickiness and more odor by now.

What do you think?

Ps. I follow the entire feeding schedule of the General Hydroponics Flora series and use every product accordingly to the directions exactly to a Tee.

55* at night is too cold if you are running reservoirs in that room. I dont let my temps get below 65* at their lowest. As for highs in my room, I seldom get lower than 72-73 or higher than 78 when the light is on. What has changed other than your growing medium since your last grows which produced more frost/smell? What kind of hydro setup are you using and in what medium? What ppm/tds are you running at? What is the ph of the reservoir?

Sometimes plants just don't smell when they are growing happy. The smell is like a deterant when the plant feels it's in danger (I think). Shake the plant a little, I bet it will smell like crazy.

Some just don't smell that much imo. I've grown the same pheno of Blue Power in soil, coco, and rdwc. Always smelled the exact same in each medium. Largest/best grow was in my rdwc. I've grown plenty of strains that just don't smell, or don't smell very good. It's harder than you think to find that good strain and pheno that meets all of your requirements like smell, taste, yield, ease of grow, etc. When you find it, keep it!

Cooler temps keep smells down. Think about standing in a garbage dump in the winter vs the summer. The smell is still going to be there but nowhere near as bad as it would in the summer. Don't sweat it. Keep em growing happy and they'll be fine.

At this point you have nothing to be concerned about. It's just too early to make any kind of judgement. Think about it for a second. The first two weeks of flower all the plants do is stretch and put on more leaf. Weeks 3-4 will see flowers starting to form but nothing major. You really don't see/smell much until after the 5th week. Even then some strains are slow to develop.

I had a pheno of Blue Cheese that I grew from seed. It seemed about 2 weeks behind the other plants. In the end it completely smoked the other strains in both yield and flavor. It took longer to start flowering so it kept getting bigger while the other plants stopped stretching and started putting on bud. It looked to be almost pure Afghani with the super broad/wide leaves so it finished the same time as the others. I haven't grown many pure Indica plants before so I don't know if, "that's the way, uh huh, uh huh, they like it, uh huh, uh huh" Watch this video and imagine KC is the Indica and the backup singers are the other plants. Same fucking thing exactly!

That was a good fucking song for my opinion, laid a lot of pipe behind it hehehe. I have a couple White Widows 75 days into flower Buds and Trichomes everywhere, and not that much smell either, some girls just aren't that stinky Uh Huh uh huh
