Rust spots
Sup3rNov4started grow question 4 years ago
Hey guys more issues with the one plant that looked like it had magnesium deficiency. Fed the plants and noticed the bottom leaf had rust spots (did not rub off) any idea if this is a lockout or needs more calmag ?

The leaf is healty i will exclude the lockout, raise a little the calmag ( i usualli give 200us ec of calmag every watering in soil ) if u have high residue in your tap water low a little the dosages. Hope to be useful and comprensive ✌️🏽

Not knowing your feeding schedule, i would more say it's a cal deficiency, and not a lockout.
I've had quite a lot of calcium issues in the past (due to having very high levels in my tap water.. an EC of 0.8, but somehow still lacking some usable calcium), which all went away, when i spent the 50 bucks on an RO filter. Best investment ever! Since then i of course always need to add calmag, but it's now all controlled and i've never had issues like that anymore.

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?

Brown/white spotHi everyone. The plant is a photo on her 7th week of veg. I give solid ferti and diluted compost tea water then appeared white spot on old leaves and the new leaves have tips burnt.
Is it PH problem or PH mix with overfed?

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?
Info in week 10.

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.

White spots on a few leavesAny idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

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.

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?

1 out of 3 doesnt do as well as the othersIm just wondering why one out of 3 plants, does not perfectly well while the others seem doing awesome. Can it really differ from a strain that it shows signs of light stress or nutrient burn while other plants seem to do well with it?
I added 3 pics, 1st one showing the meh one

Normal trichomes or something bad?Dumb question, I started noticing this on my leaves. I recently battled with insane humidity which I was just recently able to fix, and was wondering if this is normal/my usual over worrying or if it's some sort of mold/mildew/fungus or something I should actually worry about.
