A bit of an indoor newbie here. I am growing in a hydroponic ebb and flow set up. She is growing fast and looks healthy... However I see there are 2 discolourations on one leaf and google is not helping. Please help. Here is my details
Strain: feminized lemon kush headband
She is 19 days old from seed
Ebb and flow floods 3 times a day.
Light: 400w HPS duel spectrum at 50cm (20in) above the plant. 18/6
Nutes: general hydroponics flora series at seedling strength. Changed reservoir 4 days ago. Res temp 16 to 18 celcius.
Ppm: 200
EC 0.4
TEMP: lights on 24 to 28 celcius (75f-82f) lights off 20 to 23 celcius
RH 57 to 65%
Using phed tap water to mix (EC 0.065 ppm 80)
Any ideas? The discolouration does not go to the back of the leaf. Only surface and is only on 2 fingers of my second true leaves. Has not spead or worsened in 2 days
Thank you!!!
