Brownish spots on the leaves
BetaVulgarisstarted grow question 5y ago
Since two days, some brownish spots / edges burnt are developing on the leaves of the CMOG, but not on the Z&Z. She is alright. What could this be? Maybe lightburn? The LED has a distance of 30 cm to the canopy, as proposed by the manufactorer. Thank you! π

Brown spotting is typical of calcium defeciency, leds can sometimes curve the plant to use more calcium especially during flower. Raise or dim the light a little if possible. Increase your calmag feed I noticed you had this suspicion before. And also remove some of those huge overlapping fan leaves. π±π

Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?6y ago

Odd leaf bitten?Hi All,
Noticed the odd leaf like this that looks like something has taken a bite of it.
It is only the odd leaf. I had some fungus gnats a few weeks ago which are now gone.
Is there something else doing this and do I need to act?
ThanksWeek 7
