First time harvest problem!!!!! Help!!

[40below]

So my leaves are getting brown spots and dying. A lot of them. I'm into my 5th week of flower and not sure what is going on. I have used almost no nutes up to this point but have been using a blooming nute since the spots have popped up. My hairs are starting to turn color a little and I think it is a little premature for this to happen as the tricomes are still very clear. My fear is that the brown spots and dying leaves are also having effect on flowers.

Looks to me like you need calmag

Right on. Hopefully can turn this around. Went out of town and had it on auto pilot. Thanks.

You should use nutes. For something cheap and effective - Dr. Earth Bloom sold at Home Depot and other places. 4 lb bag is $10.98. It had nutes and also biotics.

Another good one is Jack's Blossom Booster 10-30-20. By JR Peters.

From what I read you should quit using about two weeks before harvest. Not sure really how to tell when that 2 weeks is. Lol.

First what type of grow medium, what type of water , what type of nutrients looks like my potassium def. (k) ....have u checked for balls or open male flowers herms or anything else...what is the breeders flower time what stran ...arenu foliar feeding or spraying ur flowerswith anything .

If im growimg a 9 10 week strain if im healthy ill flush at week 7.5 in ur case id flush at week 8.5 because ur onviously lacking nutrients already

I use tap water thats fairly hard adding calmag for me would lock me out of multiple others phosphorus will usually give u purpling splotches on ur leaves and purple stems.... pottasium will cause yellowing and what almosst lookss like nute burn with dead tips edges and possibly necrotic brown splotches on leaves.

Thanks for the replies. I am growing peppermint kush (Barney) in soil. Using well water. I let my water sit for a few days before using it. As far as testing for nutes I have no meter. I plan on growing more in the future but only after I build my shop. My wife isn't down with the weed smell in the house. I am only growing one plant so shouldn't be any males correct? And what is a herms? From everything I have read it is the 3 P. C &M.

needed more food

Looks like a PK and probably cal/mag deff might have done with some extra N too

Depends how long your keeping that one up as to what you want to do

I would feed light npk, cut off all shitty leaf and see

probably would give it a week or 2 and swap to just feeding K and crop it a week or 2 after that she looks like she`s ate all her fat (fan leaves) so that bitch is on a root to buds diet now, lol

Calmag has nitrogen in it so be careful using it with N nutes or ull lock out ....

calcuimphospate build up can also cause problems normally when people with hard water use cal/mag with bloom levels of P this can happen if you don`t have good bacteria or zyme

I give cal/mag during veg and a few times during flower never a staple or I cut the P down some when I use cal/mag

Lots of people there with calcium phosphate issues that never seem to work it out.......

by the time they start looking really yellow in bloom cal/mag won`t fix much and you want to start cutting cal/mag near harvest

cal/mag is a bit useless if your cutting the plant in 3/4 weeks or less

Update.
Here are a few shots of the buds. A few at the top are huge. Maybe 6" long and 1-1/2 thick. Happy with my first grow. I think I will try my hand at a larger grow now that it's legal here. Thanks for the help!!
