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.

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

Alright peeps, here's one for you. Still don't know what it is. Pictures attached to Week 9, Veg. This has been occurring since week 3. There has been NO spread, it is always localized to only 1-2 leaf blades and she is not stunted at all (largest girl). Please PM for more info

Leaves yellowing
These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

Possible calcium def. or other issue affecting leaves and buds
Is this a calcium issue, and if so why is it spreading to this one bud in particular? There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

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.

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?

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
