Weird rusting of leaves, what do my babies need?!
Robertsanswered grow question 3 years ago
Your ph is out of range is my first guess. If that is correct then you are calmag short, if they are autos they will be wanting extra potassium soon to. Good luck

Shot in the dark here, but that looks like what happened to my plants when I switched over to LED light and had it too close (light burn). Are the affected leaves dry / brittle? How high above the leaves is your light, and if it has a dimmer, what power level is it at? I find it very easy to underestimate the power of LEDs.

Hi there,It's seem like soil or pH problem to me.Your temp, RH and other parameters are ok.If FFOF is the only soil you used , I think it also should be fine.And also I see you don't add any pH up/down solution to your nute mixed.Is your solution pH around 6.0~6.5? Before you make any correction, check both of your pH in/out and ppm in/out.Happy growing... ✌️

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?

First grow with autos, are these growing too slowly after a week?It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

Spotted LeavesMy ladies looked good until recently, it has been very warm the last few days. Then they began to let their leaves hang down (didn't get enough water) and gradually turned yellow, now they are getting spots. This is my first grow and I am not sure what it could be.

New growth looking strange and growth slowed down (wilting?)The new growth of my plants are looking a bit strange, and growth seems to be slowed down.
Could this be that the light is too strong? Or can this happen if the humidity is too low?
I already installed an humidifier but looks like its not helping.
Whats going on?

Tiny holes!?This morning while looking I noticed tiny little holes on some of the leaves on one of my plants. I didn't see any pests with my eye, and I tried to use my phone the best I could but couldn't see any. I've also heard this could be environmental/viral. Any thoughts or ideas?

What is this Jawn on my Leaf Device?What is this on the leaves? Brand new clone 1 hour in my ownership. I sprayed her with Bonide Captain Jacks Copper Fungicide in case it is PM. Doesn't look like PM though. Looks almost like hard water deposits. What do you guys think?

Identify Issue: Brown Spots, Lower leaves first, from outer-tipsShowing up on 2 out of the 5 in my soil bed. Front 2. Transplanted 10 days ago, went well enough.
Watering with tap water, never tested but didn't have an issue last run. Same soil, but I did add 8 cu ft of new soil to the top. Gently amended with b6, Kashiblend, coconut powder.
