Deficiency
Ahtoh_mgrowstarted grow question 5 years ago
Spotted a deficiency on my AK 420
Checked on growweedeasy charts and Imo it's a cal/mag deficiency.
I meticulously check Ph and runoff and she had the same treatment as my royal dwarf.
Probably more hungry than the others.
Just wanted to make sure, cal/mag deficiency right?

Yellowing LeavesI'm concerned my plant may be prematurely yellowing. I've added Cal-Mag to see if that would help with the yellowing of leaves, but the issue persists. Yellow leaves are moving progressively higher up the plant, but my other strain is not presenting same problem. (See Post)Week 18

Nutrient burn/deficiencies/feedingHaving difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses.
One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farmsLeaves. Curl down
