Bottom leaves yellowing and turning up

Imo nothing wrong with rainwater if it's clean. You may need to add back some minerals like calcium or magnesium if your nutes aren't meant for rain/RO/distilled water.

Again nothing is a rule but being aware of the differences is important.

Is it ok for the light to be 15in away from the plants and turned all the way up? I know they’re supposed be stretching so wasn’t sure if the light needed to be higher.

Edit: Still in Week 1 of flower.

Dang ok I’ll move it up when they wake up later. But you think having it at full power is ok?

Why would you do that when you have a dimmer?

Do you enjoy getting sun burned?

 

[Aqua Man]

Yeah it as @growsince79 said you can cut it to half power? It's hard to say but read the plants.

It was my understanding that during flower you want more light closer to the plant. Must have been my mistake.

You do but I think that's to much. You can try it and see how they respond

Gotcha. Sorry still learning here! Will be much more knowledgeable on my 2nd grow.

You do but people tend to think the plants can handle it simply because there LEDS but its just not the case a bright ass light at 18 inch is still a bright ass light.. at 18 inches :P

Somebody might recommend a light meter app for you soon but if you want to check it out old school you put the back of your hand at the height of the plant tops and hold it there for a solid 30 seconds and what you feel is what the plants feel all the time; it's a pretty good indicator of whether your light is too close or not good luck

So many mistakes I made on this grow!! I’m surprised they have even made it this long. Thanks to you guys on this site I’m hoping the next grow will go much smoother

I'd love to see someone grow perfect weed from start to finish there first time lol

Mistakes are how you learn.

Yeah bro LD nailed it... Nobody makes a perfect grow. The more mistakes you make the more you learn and the better grower you will become. After a while you intentionally will try things just to learn. We all started there, nothing to be ashamed about. One benefit is you can draw on the experience of others to help speed up the learning.

Hell I'm doing my first soil grow for the learning and let me tell ya it ain't perfect either but I'm learning.

Someone correct me if I'm wrong. I think a light 2 ft above is 1/4. as Brite as the same light at 1 ft. Knowing that might help figure out the dimmer.

Nope it's not linear like that but I can't remember the ratio of loses. You can search online.
