I think you got more than one thing going on with this plant. Definitely a rootzone problem, either overwatering or pH. Address this first before playing with your nutes, they may be linked.

What’s wrong!
Any ideas what’s wrong with this plant? None of my other orange sherbets look like this & they are all in the same environment & getting the same nutrients?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?
Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Please help! What am I doing wrong? I’m a first time grower
My leaves were burning and now I know that I am burning it with nutrients cause my soil already got nutrients. I’m only using water now but now they are turning yellow and the big leaves have spotting. What’s the problem now and how can I fix it?

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

possible deficiency?
Please help. Noticed some yellow leaves, some misshaped, fallen off. Should I water to correct deficiency or wait for normal watering cycle? I watered 24hr ago but starved them for 4 days prior thinking i had fungus gnats. Temp dropped to 15c usually 25. Thanks

Small brown points on older top leaves
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.
