Revisa las dosis de nutrientes ya que no están siendo suficientes, ahora si no haz comenzado a fertilizar ya es hora de comenzar con pequeñas dosis 💪

I have not amended at all. I guess I need to start adding nitrogen? I will do more research and then start small.

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.Leaves. Curl up

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?3y ago

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼Week 20

At what stage do leaves get darker ? This is confusingI overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?3y ago

Black discolouration on leavesOkay so the problems with the black spots continue only on one plant. I tried reducing nitrogen and increased calmag to 4ml/g. I defoliated the affected leaves and sprayed with baking soda mix. 3 days later they're appearing again. If I don't get this fixed soon im gonna lose herWeek 2
