That yellowing must be because the plant needs nutes
Maybe. I don't see a little yellow as anything to stress about, certainly no reason to start adding more nutes. I'm more worried about salt buildup and ph then a yellow spot on one leaf.

That is a nutrient deficiency.. You won't have to worry about ph and salt build up if you water with rain water

not everyone goes out and collects "rain water" bro, hell if i did that all my plants would probably die since theres like 4 cement plants around here and god knows what else spitting chemicals into the air.

My air is pretty clean. I may convert to rainwater but if there is a dry spell I will go back to tap. The switch could shok my plants though

back off the nitrogen, pilgrim. they look too "rich." especially for flower. imo
you're always one step ahead of me. I found it funny that Fox Farm calls for such high nitrogen right through flowering but followed the schedule anyway.

And to Bombasticon: you're probably right. I just tend to take a holistic view of the plant. Yellowing on a leaf doesn't bother me. Yellowing on a bunch of leaves before week 6 or 7 would. Aside from using chemical ferts, I try and be as laissez faire as possible. I feel that too many beginners like myself get too worked up over any sign of anything wrong. As scroglodyte said, they look too rich if anything. I feel that adding more nitrogen for one yellow spot is over-kill. Now the c99 has a yellow spot but hasn't had nutes yet, which tells me it wants nutes.

eventually i'm gonna get into the tea's and rainwater. I just want to get more experience. I've done 3 grows over like a 5 year span, so I'm still a super noob.

rainwater isn't what is used to be. in the city we've got high density populations, with excessive motor exhaust and smoke stack factories pumping all types of chemicals into the air which is brought back down on us in the rain water. It's still worth a shot collecting the water and trying it on your plants, we may be wrong about the water, but i doubt it. I live out in the country, far from all the city pollutants, so my rain water must be sparkly clean and perfect, right? Wrong. I am surrounded by monsanto corn and soy fields. Every summer literally tons of nitrogen fertilizers and strong herbicides and pesticides are dropped onto endless acres of monocrops. These chemicals then are carried up into rain clouds via evaporation, the clouds travel, and then dump their polluted water back onto new ground. My rainwater may be worse polluted than that of the inner city. Not to mention the same chemicals are in the ground water now, so my tap is even worse than the rain I'm sure. There is no such thing as clean water on this planet any more. We humans have gone out of our way to make sure of that.

Pretty sure your wrong I use only rain water plants are fine, all you have to do is strain the water properly and your good to go

Straining won't help with most pollutants (unless you're using RO or some serious filtration, in which case why use rain water as your source at all?), but it will get rid of insects, dust, and maybe even pollen. However, I'll agree with you that the earlier poster was probably exaggerating pretty severely. Our air and water quality in the U.S. has actually improved remarkably over the last few decades, due to a combination of tighter restrictions on motor vehicles, monitoring and restrictions on factory emissions, and the shifting of a large portion of our manufacturing overseas. There are some rivers and watersheds that were essentially toxic in the 1970s but are now pretty safe to swim and even fish in.

That being said, I'll also agree that if you live in an agricultural area, the large scale spraying of pesticides/herbicides/fertilizers will almost certainly get into your rainwater, and probably your local river/lake water as well. I don't know if it would be at levels that are high enough to effect your plants at all (probably not), but it'll be there.

If you're in the suburbs and there aren't any major industrial or agricultural areas upwind (prevailing winds, which usually means to your west in the U.S.), your rainwater is probably pretty clean. If you're right next to a major highway, or in the heart of an urban center, you're probably still getting a lot of particulates from vehicle exhaust, even if the per-vehicle emissions are better now than they were 20-40 years ago. Once again, I don't know if the pollutant levels will be high enough to effect your plants (again, probably not), but there will be measurable pollutants.

In sum, even in the worst areas I'd guess your plants won't suffer from the pollution in your rainwater. If you're in suburbia (and not downwind from an industrial park or agrobusiness district), you'll probably have pretty damn clean rainwater, almost certainly cleaner than your tap water, once you filter out the dust/pollen.
