Hi folks
My seedlings are just around 2 weeks old, I've been watering them with PH-ed water, after 10 days I fed with 200ppm worth nutrients, specifically, I gave the bottoms a quick dunk on the nutrient solution. The roots are exploding out the bottom, which is great, but the leaves aren't looking too happy in general. One plant specifically is showing purple under the leaves.
I thought it was overwatering at first, but they've pretty much dried up and are still not looking happy. Could I have introduced nutrients too early?
Temperatures are around 20c (68F) with RH around 35%. I give them a boost to 25c (77F) and 70% RH around 3 times a day. I moved them from 30W led to a more serious cob fixture putting out around 100W over the weekend, could this be light's doing - they're around 15" away?
They just don't seem to be happy. I'm currently planning on watering them again, with just PH-ed RO water, but I want them to dry out nicely before I do so, so will keep an eye out for signs of underwatering before I do that.
