I am supposed to switch from liquid Koolbloom for the next week to dry koolbloom. My trics all still appear clear so I am hoping it is not too early. ANy experience will help if you can offer a suggestion. I posed this advice query last week as an update but I don't think it was read and was not responded to, so I will repeat my questions to more experienced growers "Now, as I am approaching the end, I need some advice. Aside from trics, is there any other way to determine approx how long left in the grow? I need to change my nutes to end stage stuff (adding dry koolbloom, phasing out unneeded nutes, and finally the flush. ) I am super worried about getting the timing right. Besides trics, are there any other clear signals that we are rounding the corner to the final stretch? Thanks in advance. Also, I live in a dry environment. A desert, actually. For real. It seems like dry trimming will be very important for me if I do not want it to smell like alfalfa after the cure. Any thoughts on dry trimming? I know it is more work, but the results seem better. My plan, so far, is to hang the entire plant upside down in 1 piece to dry. The only question is, how many of the large fan leaves to leave on. Some leave all, some leave only the small ones in the buds. Any thoughts will help me decide along with my other research. Thanks!" The time lapse just doesn't seem that interesting during later flower. I made a mistake with the server and am debating phasing it out. I will decide soon. But please. Calling all experienced growers! I have done a really good job of my 1st grow so far, and i am surprised and delighted by it exceeding my higher expectations. But now variables come into play that are overwhelming for a first timer as far as end stage quality, during the final part of flowering and ripening and curing. I have been blessed with big, beautiful frosty buds. I really want to ensure I finish, ripen, cure, and dry them correctly. I have been blessed so far, but right now is make or break time for my late flowering. I need experience that I dont have. If you can offer advice based on your own real world experiences as far as these timings, please do. I may not take it exactly, but everyone elses experiences can help me gauge my next move. Thank you all in advance for advice, and for supporting, following, commenting, and such on my first grow. I really love this place. Thanks to the devs for giving us this space. I am watering daily in coco, so i can adjust very quickly if conditions change rapidly, if that point is not obvious. And once again, i am grateful you all have commented on my grows in the past. My inexperience is coming into play in a major way as far as timing for end stage nutes and flushing and how far in advance to do this and drying/trimming in desert like very low RH conditions. If you can assist me with your own experiences in any of these areas, i would be oh so grateful. Thanks again, in advance, to all my fellow gardeners.
