buds getting dry? HELP

Yeh, my plants around about 7.5 weeks old, and after a huge storm nearly wipeing them out (one plant, 2 limbs were split, which i put a "splint" on). now, a week or more after, the tops of most buds are a little dry, but they definatly appear to be growing still. Also ever since, ive been getting yellow leaves, this was NEVER a issue b4 the storm. Is this common? or are they damaged in some kind of way??. I'm farely certain they arent rdy for harvest, being Haze plant they are 10-12 week plants. Therefore I think they need another 3 weeks. ill get some pictures up here in a few hours for reference.


Also im worried im not going to be able to tell when they are to the point i need to stop fertilzing them. I do not have a 30x microscope nor does the stores around me have them. should i stop when most hairs are 50% red?? seems to me its like 15-20% and i dont see any white ones really.

Dont panic, most likely everything is fine. Marijuana is a very tough plant. Most often the plant will recover with no effects from a split branch after you splint it. If it was going to die you would see it beginning to wilt first, not get dry.
It is normal for fan leaves to begin to yellow then fall off during flowering.
Find a 30X. Its a must have. I recently got a 30X following advice from somebody here on rollitup and I cant believe I lived without one all these years. Without one its basically guess work. If you dont have a credit card borrow one and get it online. I bought mine on Ebay for 10 bucks plus a few bucks shipping, but you can get them anywhere. Search for 30X Jewelers loupe, or watchmakers loupe. If you must figure out when to harvest without one, you can follow these tips in fdd2black's tutorial thread on harvesting here:

Hope I helped

Check the stem all the way down for splits, if you find one, tape it
