Can someone please help me diagnose this problem?
At first I thought it was root dry spots from the drip watering system but it’s gotten worse.
The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves.
Anything helps, thanks!
Heya!
That does not look like nute burn to me, looks like a magnesium deficiency. Early stages are represented by yellowing then browning into 'rust' like spots. (https://www.growweedeasy.com/cannabis-plant-problems/magnesium-deficiency)
Make sure your pH is 5.5-6 for coco/hydro or 6-7 for soil. If you know your pH is good, add a little calmag next watering. Another option is to use epsom salts in your water.
Cheers and goodluck!
you my friend have a nutrients burn. I recently went through that, what I did was gave them no feed, just ph water (6.0) and they bounced back within a week after the next feed. I hope my advice was helpful my fellow grower.
