Master_weedastarted grow question 5 years ago
Hello to all padawans and jedis masters

On my pictures (last day 20) I took the deficiency.
Thank you all for your help and may the strength be with you 💪

J'aurais dit un maque en potassium ou en magnésium , ça parait difficile a croire vue la terre que tu utilise et l'apport d'engrais que tu a fait dernièrement. Comme dise les autres c'est peut être le PH , celui de ton mix est compris entre 5.5 et 6.4 donc en gros la moyenne est de 6 et tu arrose autour de 6.3 , sachant qu'en terre ces 2 éléments( Mag et K ) sont mieux assimilable entre 6.5 et 7 tu pourrais avoir défavoriser leur apport par ton ph de 6.3 et donc entraîner un manque de ces 2 éléments due a la difficulté de les assimiler correctement.
Ça peut se tenir mais j'ai quand même un doute

Don’t write it in stone but I know of four possible causes 1- Needs Cal-Mag. 2- fert. burn 3- brown spot leaf fungus. 4- transplant stress Because it’s only on first set leaves I tend to think it’s transplant stress. I would add Cal Mag as it takes a lot to over do. I’d wait to see if problem spreads to any new upper leaves. If so not transplant stress. Hope this helps but I get the feeling more of test to see if the “force is with us” then a problem you already know the answer to. I probably failed.

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.

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

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?

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.

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?

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.

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?

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.
