Brownish spots on the leaves

BetaVulgarisstarted grow question 6y 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. 🌱👍

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

What could it be?I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

My plants are 70 days or 10 weeks old but due to I used low power led first they didn't grow too much in starting. Now I am using 80 W of LED. I wanna ask if you guys can look at them and tell if they are ready for flowing?

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Discolored leaves, rust spots, and burnt tips Began with burnt tips, followed by rust spots on upper leaves. Then top leaves of new flowers came in yellow, followed by bottom leaves developing gross pale spots. Not sure why, please refer to my super soil recipe as well as the one feeding I did in week 5. Underfed, pests, ph?

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? Thanks

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Deficiency?OK so my plants are in week 6 to 7 of flower. I'm seeing what I thought was a potassium deficiency. The nutrient line that I am using is Remo Nutrients. I added an extra bit of Astro Flower (which has the most amount of "K" in it) to the last couple of watering top ups. DWC.

Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.
