Am I close to harvest? plenty of pics. Fan leave discolored too. plz help. first grow

Ok, so I honestly have lost count on how many weeks I've been into flowering on my beautiful ladies. If you've read my earlier entries, you already know that this is my first grow. So far, I've had no major issues or problems, despite my lack of up-to-standard equipment. I need better lights and a ppm meter and that will be my next investment. But right now, I'm working on a very tight budget and can't make that purchase for a few more weeks. Anyway, I think I am around 7 weeks into flowering and unfortunately I just took my first clones. I know it will take longer to take root, but hopefully they will turn out ok. Right now, I'm unsure how close I am to harvest. I know I need to flush free of nutes 2 weeks prior. Look at these pics and tell me how much longer I need to be using nutes. When can I start my flush. I'm trying to be patient, but I am so ready to try out my first grow!! Also, the last pic is of my fan leaves. Several of them are becoming discolored like this one. Is this from nutes?

ide go 9-12 then staret flush and go for 12-14 days for the flush looks preety good but a ways to go yet prally sativa doinat u know strain

I think the best way is to tell via the trichome's (not sure on spelling exactly.) by looking at it under a 30x or 40x magnifying glass/microscope($3 on Ebay)

i regularly forget exact dates myself so i use a microscope. a week too much is better than cutting early imo. i dont flush either coz i work with soil/organic nutes and it doesnt really need it.

I'd get a microscope - it's really the best way to tell and after a couple of harvests you'll get to know your pheno an know exactly how many days left. If not my guess would be about 2 weeks as said ^

thanks for the advice. I am investing in the mag glass TODAY. I'm sure there are posts already on what I should be looking for. I'll do a search unless anyone knows of any right off... But no, I do not know for sure the strain, but I am pretty pleased with the look of it. My other lady's buds are not near as pretty and there are no red hairs at all on it. I started with a bunch of bag seeds and ended up with two females. I'll post pics of the other as she gets farther along. However, these plants are in the same bubbleponics systems and the roots have grown together, so flushing this one that has several red hairs also means flushing the other. So, should I avoid flushing this one altogether? I just took clones from this plant I've posted pics of here. I know it was late and it's going to take longer to grow, but I'm learning as I go and am working with very limited funds. SO... my next grow will be a bit more organized and I'm certain I'll have better results... but where should I go from here on this one? Thanks so much. I love this site, btw. It has been very helpful.
