Looks like you have overwatered the plant, maybe also incorrect pH

Over watering, too much nitrogen (curl), and possible micro nutrient deficiency or lock out. PH?

Nitrogen toxicity from feeding too much or too often (or both).

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

High Leaves stress in the last week!! PLS help!
Hi everyone! First indoor grow with autoflowers. Everything was fine until week 6, even after topping, but now in mid-flower the leaves show clear stress. I thought it was CalMag, but supplements haven’t helped. Any advice? I don’t want to lose my first harvest.

Problem in my cultures and I can't find what they have.
hello, I have a problem on all my crops at the moment I can't understand all this could come.the last time I put RQS easy boost fertilizer in a seedbed. I water them as soon as the top soil is dry. I added bio nova X-cel 5ml/10l to my water. I really can't understand the symptoms

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday). Do you think is this a problem? What can I do? Thank you. Peace

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!

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

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.
