Hello all, and thanks in advance for any assistance you might be able to provide. As mentioned in the title, I am a first-time grower and it looks like one of my Jack Herer autoflower is in a bit of trouble. Can any of the more experienced growers give a sense of what's going and what I can do to remedy the situation. This plant is about 75 days from seed.

Some background:

I hope someone who knows chimes in, that looks like calcium deficiency, look it up and compare. Hope you get it sorted out.

Hmm. Good question. I would have expected it to last at least thru harvest - of an autoflower, anyway. In this case we're at 74 days. I stopped by our local grow supply store and asked them about my situation. After a 20+ minute discussion and a review of some pics, I walked out with a couple of free samples of Fish Sh!t and some Roots Organic Buddha Bloom. Will give them a try at next watering.
