All 6 plants are droopy like they are overwatered, but they are a little crisp to the touch as well. The yellow/browning leaves are very crisp and are worse near the bottom of the plant.
Two of the plants have been in veg for about 3 weeks, four have been in about 2 weeks. The younger plants are showing very slow growth compared to the others.
There was one other plant that died last week. It showed the same yellowing at the base of the plant, then the leaves and even the stem started drooping and it was dead within 24 hours.
There has also been more algae in my system then I have ever had before. I have tried flushing my system and running just pure water. The plants didn't get any better, but they didn't get any worse.
I am growing in hydro. PPM is around 850-950. Ph is about 6.3. Water temp is 70 deg. Room temp is 73 deg. Humidity is btwn 20-30%.
