Hola, tienes que mirar el pH del sustrato y del agua sobrante para saber si estás en los niveles adecuados, 6-7 es lo ideal. También es muy importante la EC del agua sobrante del riego ya que así sabrás si están aceptando el alimento o no. Normalmente los sustratos vienen con más abono del que nos imaginamos y sobrefertilizamos las plantas, me acaba de pasar. Tienes que esperar a que se seque bien la tierra y ajustar el pH de riego. Con esos nutrientes que le agregas seguro tienes el pH bajo y la EC demasiado alta, ahora no notas tanto los problemas, pero más adelante no tendrá solución. Escríbeme por privado y te mando un artículo que te lo explica todo al detalle.

It could be magnesium or potassium deficiency. You look to be feeding kinda heavy on nitrogen. Npk ratio for vegging is 3-1-2. I would worry about it. Not is a sign of inexperience. I would start with readings of ph from run off. Tds, ph. Is always first place I investigate.

Organomananswered grow question 3 years ago

I would not worry about it, at this age it is most likely just a slight mutation that the plant will grow out of. Quite often the first rew leaves can have strange things happening while the plant is still trying to work out what all this "living thing" is all about. A dose or two of half strength soluble trace elements (available at any garden centre) may help, and if not, trace elements are essential and should be given every 4 weeks or so anyhow.

Die gelben Verfärbungen deuten für mich auf einen Magnesiummangel hin. Ich würde Mg hinzufügen und beobachten. Falls sich die nächsten Tage bräunliche Flecken zeigen zusätzlich Kalzium füttern =)

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
