Okay so I have two plants, they are dutch passion auto bluemazar, in 10L and 15L grow pots. A 300w led grow light about 30 cm from the plants. A fan blowing cool air around the pots and leaves. And a maintained temp of 70-80 F. They are at the 3 week mark now and all had been good until now. The light cycle is on 20hrs light 4hours dark
the leaves feel dry and brittle, and seem to be drooping down (not stretching up reaching to the light like they usually do). The edges of the leaves have also started to curl upwards. I have read around and heat stress comes up a lot also with ph in balances and nute burn.
so I have now flushed the soil, tested the run off ph at about 6.0. Re watered with just water no added nutes. The nute mix I was using was dutch pro A + B, only at 50% of the recommended levels for vegetative growth.
Any advice would be appreciated, I flushed the soil 2 days ago.
