Help?! Deficiency or Light Burn?

IndicaSmoker239started grow question 4 years ago

Need help with my plant! Can’t tell if it’s a deficiency or light burn. I’m growing in SoHum Living soil, which is a water only soil, and have only been in it for 2 weeks (7 gallon pot). This is also my first run with my new MarsHydro TSW2000 and I had it at 60-65%, and at 21”

yellow/dark discolouring of leaves late into flower Noticed this on about 5 leaves, some more affected than others. The plant is towards the end of the flowering, with about 3 weeks left, better to ignore it now or try to do something ? perhaps leaf Septoria, already increased air flow and decreased humidity

Yellowing and dropping of leaves Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?

Yellow spots on leaves Am I correct in assuming that the spots on leaves were probably caused by ph fluctuation? If so, is there anything I can do besides flushing with proper ph water?

Yellow leaves question.Good morning growers, I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Troubled seedlings Is this nutrient burn? Had what looked like a lack of nitrogen early on, lowest leaves were healthy then quickly went yellow and worked up. Now have fed nutes at 0.7EC (tap water left for 24hrs to 0.28EC) so fed under 0.5. Bio-grow 0.5ml/l bio-heaven 1ml calmag 0.25. Thanks
