Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Been discovering these little burns and holes on all the plants, Pic 2, 3 and 4. I'm assuming the burns are the precursor to the holes but I'm unsure, maybe they're not related. Any clues as to what this is. I want to stop it ASAP Rocky

I'm starting to see my upper leaves turning a bit yellow in spots. I think I may be over watering. I've added 1 gallon water to 3 gallon pot leaves looked to droop a bit.

Do my girls look healthy? There's small lighter green patches here and there and some leaf curl. I might be a over analyzing/reacting. I'm a little paranoid but autos supposed to be finicky and stunt easily, and can go from bad to worse very quickly, from everything I've read.Thx

Damage, Deficiency or Maturity
Turned her around, on leaves at wall, lower, one of first stems. From bottom up. Didn't clean drip pan when should, used molasses, was fermenting. 8/9 weeks in flower. Scoped, the leaves are browning. Nothing on the leaf, like mold. Damage, deficiency or maturity?

What's wrong?!?
Help! I thought I had this. Is this calcium deficiency? I've been using treated water (1tsp CalMag+ 1tsp Grow Big per gallon). It's just getting worse. See photos and descr. from past few days.

Help. After months of babysitting my "autoflowering dwarf" it's finally started flowering. In the last week though all the leaves have become mottled and yellow with burnt brown edges. What can I do to save her?

So at day 55 I'm noticing that some of my leaf tips are looking a bit burnt and some rust colored spots are showing up on the leaves. I read that this might a deficiency of cal or mag or a ph issue. Just wondering if any one could help my diagnose this issue and try to fix it.

Light green "splotches" on leaves
Hi, I've noticed light green "splotches" on my leaves which I'm having trouble matching with images of leave problems. Doesn't appear to be impacting on growth and the issue is only visible on close-up so it might just be me being over concerned, but I'd be grateful for advice!

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]
Hey guys! Do you think these are thrips? The leaves have these white snipes already since some days ago. Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves. I'm thinking of adding potasium soap for this.

Does this look like minor leaf burn, too many nutrients or something else?
I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.

Yellow Leaves Autoflower
Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

Having persistent yellow/brown spots on my leaves. Took a close up picture to show them better. I adjusted my nutrient schedule to increase phosphorus content. pH is checked daily. What else can I do to eliminate the problem?

White/Yellow snipes on leaves? (13th day of growth from seed)
I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions. I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Phosphorus Issue?
Slurricane is having a phosphorus issue and not drinking water as fast after transplanting. I’ve been feeding cal mag every water and thinking it’s a root zone issue. Should I apply stop watering and apply a follar feed of 3 part general hydro nutrients?

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!
