Why are there soon many brown spots all of a sudden in WK 7?

ElevatedThinkingstarted grow question 6y ago

I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

You may have overfed her, causing the dry brown spots and burnt tips I see, this could have then caused nute lockout. Flush the medium and apply a foliar spray until she’s ready to be watered and fed again.

Looks like a calcium deficiency to me , in fact if you type "cannabis calcium deficiency" on google the 1st pictures will all looks like your leaves with the brown spots. Maybe the flush you did to correct the ph have washed away the calcium or maybe the ph fluctuation you just corrected have cause a lockout

The purple on your leaves is most likely genetic although the strain you're growing is not meant to be purple some times it can happen especially if the temps are low. The spring on the leaves is most likely a calcium /magnesium deficiency can easily be solved by adding cal mag to the feed (this is quite common) 🌱👍

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Discoloration and Spots I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.

Late Flowering Stage Deficiency or Nutrient Burn I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

Saw this first day of 12/12 Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!
