Conoces el pH de tu sustrato?
Quizás no lavaste bien el coco que estás usando o de simplemente no lo lavaste.
Una cosa que he aprendido es a siempre a medir el pH del agua que voy a usar sin importar su fuente: el agua de osmosis inversa no es raro que tenga un pH muy alto, lo mismo para el agua de lluvia (yo la he medido y me he encontrado con sorpresas como un pH sobre 8).
Yo lavaría el medio con agua de pH al nivel adecuado, idealmente 6.5, pero nunca mayor a 7.0
Lo puedes bajar con soluciones que venden (pH down) o artesanalmente puedes ocupar un gotas de vinagre de manzana.

translucent pest in soilHi, last watering I've seen tiny translucent insects (about 1 mm) emerging from the soil. They are fast and can jump like a flea. I assume they live in soil. What are these little monsters, should I worry about them and what should I do ? TIA

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.
Would it be the only way to smoke bug free weed?

What and why?What are these and do I need to address it?
I'm a couple of weeks in to my grow and just spotted these little critters when I was cleaning my run off saucers. I'm guessing there's more inside the soil are they harmful to my plants?

handelt es sich bei den Tieren um schwarze blattläuse? (Habe leider keine besseren Bilder hinbekommen)
Ich habe auch einige größere schwarze Tiere mit Flügeln an ähnlichen Stellen gefunden.
Denkt ihr mit Wasser und anschließend mit einer Seifenspirituslösung abspritzen reicht?

BugsJust noticed a small grey Rollie pollie looking big on one of my seedlings. Only found one and believe I killed it but what should I do to prevent/get rid of these bugs. I have another seedling that I didn’t see bugs on and a flowering plant that hasn’t had any issues with bugs

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

What are these bugs and what to do about them?Hi,
I spotted these on one of my balcony plants today. Somekind of mites?
They were around the sugar to middle sized leaves on new growth. It's around early to mid flower.
I removed the leaves that had the most on them and tried to get rid of those who were left. What else to do?
