Hongo mildiu?

JuanHaze_Argstarted grow question 4y ago

Hace unos días, las primeras hojas presentaron zonas con necrosis, y día a día avanzó. Será por el riego foliar con ? Por el viento directo del fan? O es un hongo mildiu? Un día la H.R llego al 80 90%, el crecimiento avanza pero muy lento, el sustrato parece tardar en secarse.

If your using soil in your mix then your ph is out. You have it set for hydroponics. Soil needs to be 6 to 7 ph... 6.5 would be best.. Cheers

Hi guys. Considering the several problems of this grow, how I can change my setup for the next grows? Now I'm using Plagron Alga fertilizers and the Promix substrate (no fertilized). Do you suggest to set the lamp in bloom mode (more reds) also during the veg phase? Thanks, M

Weird leaf ends missing/holes My plant (mainly top leaves) have been developing weird holes/ends missing over the last week or so. Right now I am thinking it is due to its proximity to light? I'm really unsure. Any help is much appreciated!

Plantule aux feuilles vert clair. Engrais organique et fibre de coco.La plantule s'est bien développée, mais ses petites feuilles sont encore pâles. J'ai utilisé la dose recommandée, puis légèrement augmentée au second arrosage, sans amélioration. Dois-je ajouter plus d'azote ou passer au stade suivant de nutrition ? J'utilise l'engrais organique.

Is it nutrient burn?Week 9 I noticed orange/brown spots on leaves and tips turning yellow. Is it because nutrient burn? Was feeding them with all the Biobizz nutrients by their schedule. Second day, 10 week I flushed the plant. Should I continue flushing 3 weeks before harvest?

All of my plants have started to burn yellow in colour when they switched to flower, they have also lost they lovely green colour and started to go lime. Too much nitrogren still in the soil? Or Just a deficiency? They have recently been fed 1ML fishmix and 2ML Bloom.
