oh btw those ladies are on week 5 of flowering

It's normal for the lower leaves to yellow and look a little beat up at about this stage of flowering. The top 3/4 of the plant seems to look ok.

I don't see a problem.

rly guys? u sure? cause some of it is spreading to the younger leaves.. i dont want to ruin my ladies when im so close to the end

I only see some yellowing on the bottom of the plants other then that they look pretty normal. I have to pull a few yellow leaves every few days, seems to me the largest bottom sun leaves die off first. I had some massive fan leaves larger then my hand that are slowly dying off all but one of my plants. It's my understanding the fan leaves us a lot of N during veg growth and when the plants start to bud they don't use/need the N which results in some of the lower vegetation dying off.

PH water to 6.5 DO NOT USED DISTILLED WATER it has no micronutrients in it and the plant needs them. Some yellowing is normal but your yellowing is showing burn from nutes. You are very close to the limit of how much that plant can take. DO NOT GIVE ANY MORE NUTES> You will complete the grow, expect many lower leaves to drop but the buds to stay green and healthy. The plant sends it's reserves to the part that is trying to reproduce and it could care less about the sun leaves any more at this point and it will start dropping them.

no distilled water? isnt it like reverse osmoze system?
so i should not feed them anymore till harvest?? wow.. thank god, i was gonna feed them tomrrow.. rly thanks! but thats odd caues i gave the nutes according to the company table of feeding..

so if im not giving them anymore nutes till harvest, should i still flush them 2 weeks before?

BTW it looks like you're going to have a few very nice cola buds there.

Distilled water is evaporated to recondense without any minerals in it whereas RO uses filters to catch the minerals and contaminates. Neither are good long term for cannabis growth.

The companies are in business to sell nutrients, 'nuff said.

Flush....how about just over water every day the last week. I never flush, but I never give nutes either.

LOL, seems like I'm having to do this daily now just to keep my plants from wilting! I worry if I'm flushing too many nutes out by having to water so often?

hmm but if i over-water every day, the plant wont show over watering stress? like falling leaves etc..?

As long as you have good drainage over watering shouldn't be a big problem, I water until it's flowing from the bottom and when I get home they're almost dry. Been in the 90's which is a factor but I'm trying to keep the area humid with tubs of circulating water and I soak a heavy bed spread with water and leave it spread out between the plants before I leave for work.

Normal watering is just enough to keep from getting runoff.

Over watering washes out nutes and if it goes on long enough the roots will rot. During the last 2 weeks it is not a big deal, so a few sun leaves drop, you would trim them anyhow.
