Hello! I am a newbie in indoor growing. Ive grown 2 plants outdoors, and 1 plant indoor. However, I recently changed all my setup. I am currently growing in DWC, with Optic4 LED. Temp/humidity is at 26 C and 45% RH.
I have googled extensively, but have not managed to find anything quite like what I am having here. Forgive me if I have not searched hard enough.
Previously my plant was by the window, growing slowly but healthily. TBH, I basically forgot I had that plant and it had been growing quite a few nodes after I topped it for about a month. I then moved it inside the tent a week ago, and have been moving towards mainlining. But the new growth have come out looking like... this [attached]. It looks like the leaves were deep-fried! I'm using a generic tomato hydroponic nutrients at 1/4 strength.
I initially thought it was because of heat/light stress. However, my Optic4 LED was already at 5' distance (60 inches) above the canopy. Is it at all possible that is still too close? As far as temperature, there is AC in the room, running 1 hour before and after the grow light is on (18/6 cycle), set at 26 degC. Just in case, I have increased the distance to 80 inches now.
I've also looked at pictures of mite infestation... But they look different to what I have here...
For sure, there are many troubleshooting steps I can still take; but I want to pick your brains to narrow down where I can start. Have anyone ever seen something like this? What could be causing it?
