Grow QuestionsDo these burnt edges look like heat stress or a nutrient issue?

Do these burnt edges look like heat stress or a nutrient issue?

zacwazstarted grow question 2 years ago

I noticed this browning on the edges of two fan leaves this morning. The affected leaves were right next to the space heater that runs all night (cold basement!), so I *think* it’s probably heat burn/stress. But don’t want to ignore a potentially more serious issue. Thanks!

I'd keep my eye on them, tbh... it certainly COULD be from the heater but it might also be the beginnings of a phosphorus deficiency.... I don't see any pH information or nute information in your diary - but you need to keep the pH between 6.0 and 6.5 for a soil grow... Good luck! Nice looking jungle so far! :-D Did you decide to keep all of them going? Hope so!

Yellow edges I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

Brown tips and edges, but not on all plants.2 out of 3 Kratky plants are showing some crispy brown at the tips and edges. Would I be seeing nute burn at 550-750 ppm? Why only 2 plants? Why only the Kratky but not the DWC? (Same strain.) (I am actually using GH FloraDuo A and B) Thank you!
