I maintain and culture coral, and I know testerial/ hydroponic plants have similar needs. My question is will a brass pump adaptor cause leaching of copper or tin into the feed water, and if so is it toxic to plant the same way that copper can kill invertebrates? Are there any simptoms to look...

Just wondering if you usually reply or post to someones question with generic answers, or yet it seems like you just didn't read the original thread but your reply seems to be covering growing in soil media, not hydroponics. And I know I am new but help would be better than getting a response...

Can some give me sum info on reasons for curling leaves??? 17 days pH 5.5-6.2/TDS 480ppm(lucas formula) RH 30-55% temp 69F-78F/5 gallon res.65F-70F watering timer-1hr. on 2hrs. off 150watt 2300K HPS/supplemental 13watt LED 460nm. timer-18hrs. on 6hrs. off

learnin my self but all i can say is WOW,thats a system!!! how big is the res.?

once i started to notice the discoloration(10/18 ) i flushed res and media, raised lights from 8" to 10", lowered TDS from 475 to 422, and finally raised pH from 5.2 to 6.0 within two days. the plant <unknown strain> seems bout the same today

so lowering the TDS was not the way to go then? Iam using lucas formula , thought chemical burn, so raise it back up? sur its defficiencies?
