Deficiency symptom for 2 weeks and in 3 weeks is harvesting with Auto Black Out

Definitely not an expert here, but i have similar issue, which in my best guess was caused by led light burn maybe combined with nutes overload :)

Have just measured the EC value of the drained water in the Potsfunters and this fluctuates between 1.4-1.8. That confirms again your suspicion with the overfertilization! Am interested in how the value is in 2-3 days!

Hola companero! I have been watering every 2 days for 1 wk 3-3,5l (pot has a size of 14l) or maximum until the water has run out the bottom. Sizes of the babies: No.1 : 51 cm No.2 : 48cm No.3 : 56 cm No.4 : 48cm I read that you should not flush organic when working with organic fertilizers. Would you still recommend doing that? Thanks for your comment anyway, as a first time grower it's really good to hear other opinions on this!

I'm not understanding your question here... sorry!

Ciao Bro,a me sembra che ci sia troppo fertilizzante nella terra,un buon risciacquo radicale con litri d'acqua a pH 5.8/6.2 Danno l'impressione di essere bruciacchiate dal troppo fertilizzante le foglie... è cm se già le dovessi raccogliere ma mi pare dal colore dei pistilli che manca ancora tempo Quindi si..io farei un risciacquo finché l'acqua che fuoriesce dal fondo del vaso, è uguale a quella che esce dal rubinetto che usi
