Brownish spots on the leaves

BetaVulgarisstarted grow question 5 years 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! 😊

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. 🌱👍

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Necrotic spots The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!
