K deficiency? Or something else?
TheProfessorGrowsstarted grow question 3y ago
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Looking good, but really hungry! :)
I'd feed calmag plus a normal NPK dose.
Make sure it's suitable for the flowering phase, meaning less N and more PK, at your stage, you might want the highest number of the NPK to be the P. :)
Good luck, buddy!!
Just a word: with organic nutes, you will have an effect for sure, but you will always run behind those deficiencies. I would get some mineral back ups!
GrowingGrannieanswered grow question 3y ago
The pH is a little high (I'd get it down to 6.2-6.3) but the REAL issue here is that you're not feeding her anything! All Recharge and Fish Shit are doing are enhancing the soil to make nutrients (which you aren't giving her) more available to the plant ... she needs a lot of P/K during flowering and not so much nitrogen... get her on some good bloom nutes along with extra P/K and she should be ok.
Good luck!

It could be she needs more p and K. Also led lights tend to make the plants use up more calcium and magnesium then hps or fluorescent lights.

Deficiencies while in late flowering during flushing periodThere is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Browning, curling of Green Crack leavesIs this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up.
Is this just a straight calcium deficiency?

Grayish brownish fuzz on sugar leavesTurned my northern lights plant around today and noticed this on the back of it. Yikes! Is it bud rot, pest damage, something else?
If it's bud rot I need to get rid of it ASAP because I have 6 other plants in the same grow room.
