Good day to everyone,
I hope someone can help me with this situation that has been driving me crazy for the past 2 months.
I have been able to harvest our favourite plants from seeds for 6 grows now, a total of 20+ plants. I am by no means a great grower, still plenty to learn. But never have I imagined I would run into a brick wall such as this.
So a few months ago I moved into a house with a proper grow room. I used to live in an apartment, used to need lots of ONA block to mask the smell. Now i have a properly equipped grow room with ventilation and carbon scrubber.
So after everything has settled down with the move, i started 6 seeds.
Everything seems fine till the 4th day, when yellow/brown spots start to appear at the tips of the leaves.
Soon after, my girls start dying.
A liitle background, I grow in soil mixed with perlite, using LED lamp.
Grow room temp is around 24 celcius/ 75F.
Humidy is a little high at 75, a dehumifier is ready to lower for flowering stage.
Water PH is measured and adjusted.
Grow room has been well aired and cleaned, so no issue with paint fumes or other contaminants.
First i thought, the seedlings are overpowered by the new 600w LED. Hehehe i collected quite a few new toys during the renovation of the new place. Ok so I started over with the old trusty 150 UFO LED that has served so well in the past.
But second batch start dying too...
Third batch gets bottled water, while the new house tap water get sent to lab for test.
Test come back fine, and my girls died too.
Maybe I had a bad batch of potting soil, so I sourced from elsewhere, different brands, different suppliers.
Nope, they died too...
Maybe the perlite I had got contaminated somehow.
So on the latest batch, i started 1 seed in pure soil, and 2 seeds in soil mixed with coco.
Lo and behold, the same problems has reared up again.
Is it possible the light is overpowering the seedlings, as the grow room is painted white for better reflectivity? Although I have tried increasing the distance to the light, which has caused some stretching in my deceased girls.
The photos are of the 3 in the latest batch.
The leaves have started yellowing, more pronounced at the tips and the centre running through the leaves.
They will be dead in a few days...
Any diagnose?
