What's up, just started using a hydro setup, and two weeks into my grow I saw browning spots on the lower leaves of my plants, I'm using the flora series nutrients in my reservoir with a ph of 6.2, I would love to know what's going in with my babies... Any help would b great.

Do you use some calcium or Ca/Mg+ beside the flora ? and what kind of water ? RO or tap (Tap usually keep some Ca)

No I don't use any calcium or cal/mag, didn't think I needed to as I'm new to the hydro process and I'm using distilled water

so you practically don't have any ca in your set up, other then what ever is in the Flora, is it Flora Nova or Flora Duo ? and do you use The Lucas formula or as it say on the bottle ?

These are what I'm using, and I'm just using the formula on the bottle

unless you have/use the Micro, but still look a bit like the early signs, maybe up the Micro a bit on your next water changes, maybe swap some of the Veg for it (like the lukas formula)

Dump the distilled water for tap instead, use a ph of 5.8. If you have a PPM meter and your tap is at least 150ppm as is then you shouldn't need a Cal/mag substitute.

just leave the water in an open container for 24 hours this will evaporate the chlorine

I'm getting same prob brown spots on the leaves. But I used bottled water. What should I use for calcium if that's the prob. I'm using miracle grow and I've never added anything to it and I'm about a month in. After two weeks the first spikey leaves got a rust colored spot and slowly got one or two more then it started and the very next set of leaves got it too.
