Hello
great forum, I am growing in soil in a 1m x1m (3 feet) tent
2 congo 1 jamaica regular seeds that turned out to be females (only 1 male, which I dumped to the compost pile)
textile pots 20 liters (5 gallons)
HGL led lights
they sprouted march 31, I flipped them may 31 (11 hours light, 13 dark)
water is mineral water (I know, but I dont pay for it), ph about 7
for the last 6 weeks, leaves have started to show white and brown spots
I have no idea why
I had exactly the same in my previous grow, which turned out to be small in yield but still fantastic quality wise (different seeds, some hazes, and an indica). I thought it had to do with my soil (I have made my own mix for the last few years to great results) and nutriments, that's why this time I bought biobizz mix soil and biobizz organic nutriments which I've used in moderation (or so I think)
The Jamaican is less symptomatic than the two congos shown in the pics
I've looked online but didnt find photographs with comparable symptoms
Any idea and suggestion would be greatly welcome
Thanks
