I have 7 white widows. 6 of them are perfectly fine, but one of them has developed spots and yellowed bottom leaves.
thanks, looks to me like a calcium deficiency right now. i tested ph again and i'm at 6.5, so there's no lockout going on. i'll try adding some lime and see again.
none of mine have been fed, and they're all approaching week four right now from seed. you can check out my grow journal at the bottom...
Agreed! White Widow seedlings are very sensitive to nutrients. I didn't add any at all until week 4. Then I did 1/4 strength until week 6, then half strength til week 8 at which point I switched to full nutrients and started taking clones.
Careful with the lime.... very careful, a little bit goes a way long way. Feed the plant a couple of ounces of nutes, give them their first taste of food.
