My seedlings keep having lower leaves die

If that's over a month old, then you have failed big time.

If you want to treat something like soil, then use a soil.
Coco isn't meant to be used like this and we've had many people come here with countless problems due to following some YouTube dude.

There's literally no reason to use coco in this way. It doesn't benefit you or your plants and you are far more likely to have issues than not.

If you really want to be organic then using some coco to bulk out a compost works. But you need to build a balanced living soil.

This post makes me thing : “I’m following everything that this famous YouTuber is doing but my results don’t match - help” You’ve been led with bad advice, and following this method and route will just cost you money and time, and lead to frustration. Either choose to go the coco route, or switch to organics in soil. Coco and organic amendments is difficult to pull off and not recommended unless you understand both organics and coco growing. Coco has different properties and needs than soil. It’s not interchangeable with soil.

So, for the past several grows, the lower leaves on my seedlings keep drying up, curling and dying. Pictured, these two girls are a little over a month old. The heat under my canopy is about 79, but sometimes rises to 81. my percentages have been a little low lately at 52%. I don't feel like 79 most the time would fry the girls, so there must be another reason. I water them properly, and I'm not fert burning them because only the lower leaves are affected. Anyone know what might be happening here?

Just over a month old, roughly same age as yours, fertigated twice/day with GH Flora in 70/30 coco/perlite. If you dry coco your nutrient salts precipitate, burn your leaves and stunt your growth.

It would be nice not to have to mix and maintain reservoirs. I've been eyeing this stuff wondering if it would work:

But after all the failed amended coco grows and no smaller amount I just keep on using my same old stuff.

What feeding chart do you use for your Flora Series nutes?

Their old one, not the new updated one meant to sell nutrient.

I only use the Micro, Gro, Bloom and some CaliMagic

Thanks for the info.
Do you follow those exact amounts?
It seems high to me.

You mean like this?.....

Since Amazon screwed up and I have a few quarts of Flora Trio, I need to start putting it to use. Saw the Grow Weed Easy schedule suggested on this site and planned to give that a try. Seems pretty damn simple.

Thoughts?

I use their ratios and then just dilute until I hit the PPM I'm shooting for.
