Potassium, correct?
I think this is the beginning of a potassium deficiency. The near neon green discoloration is what caught my eye. This leaf is affected the most. Second week of flower. The Alga Bloom was just increased from 2 to 4ml/l earlier this week, so she should be alright. Right?

Cutting fan leaves
Just cut my fan leaves 😳 the stems we’re turning people, if I’m not mistaken it’s an early sign of an old leave that’s not as efficient in the photosynthesis? and it was covering the new growth, Or should I have waited?

So, something has happened, thinking it's either a nute lock or cal-mag deficiency so thinking a flush and then no nute feed with cal-mag. Should I be worried? Is this at all save-able? I fed them with bites about 4days ago. Really don't know what to do

Cal Mag from LED too close?
Brown spots on upper leaves mostly. Light was at 14" from tops, Mars says 18"-24". Top leaves got light bleached too. Moved light to 22", recalibrated ph pen assuming it's cal mag, given 2 feedings @ 1tbsp cal mag/gallon. Any other possibilities? Not bugs, I scoped it.

Will plants with Nitrogen toxicity go back to normal green color after they recover.
Will plants that have turned dark green with clawed leaves from nitrogen toxicity turn back to a normal green color and the leaves straighten out or will it stay like this? I flushed her Jan 2 and watered her again on 1/9. She hasn't started growing yet and still dark clawed

Magnesium deficiency? How to cure it?
Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance

Hi all growers, today I did the usual check and after 48 days, I noticed some problems. As you can see from the photos, some leaves have these defects. What could it be? The rest of the plant seems to me to be fine ... what do you think? Thanks to those who will answer me.

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?
