Spots on leaves

HappySkunkstarted grow question 6y ago

Could this be the beginning of a Phosphorus deficiency? Or something else? It’s not really found on my oldest branches, but more my newer ones.

I would say that's a slight calcium defeciency, just add some cal mag to the feed.

Noticing slight brown spotting on a couple leaves accompanied by the tiniest little bit of yellowing/tip burn on the very tip edge, any advice?Noticed today prior to feeding that i’ve started to get some slightly brown spots on 2-3 fan leaves and also noticed lots of tips starting to show the tiniest amount of burn on the tips. Dropped nutrients to about 80% dose and added some calmag. Any advice would be great.

Plants are burning part 2 Added some Bud Boom (0-40-23) to give a kick of phosphors…. Most of plants are turning yellow and burning that’s problematic ! What’s about phosphorus with my watering ? Maybe Cal-Mg? Or even are the roots to compact on the bottom of the pot ?

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Leaf mutations in Northern Light Automatic (RQS)Hello. Could this leaf mutation in Northern Light Automatic (RQS) be dangerous to the plants? What could it be caused by? Could this be caused by too much light for the sprout and the Top Crop Green Explosion fertiliser? The leaves grew very strong in a few days after fusion.
