Looks like the beginning of calmag def.If you havn't used it get some asap before it gets worse.
Hi , I have 620w led , nutrients is AN Connoisseur Grow and Connoisseur Bloom (that what I found in my growshop ) , B52, I have Sensi Cal/Mag and Aptus Ca/Mg. My tap water is 8.5 that is why I don’t use it , I buy bottled water it 6.0 ph , and when I mix nutes my ph is 6-6.5 (color of GH ph test is yellow with green or light green and digital ph Hanna gives me +- same results) , soil is Plagron Light Mix , 15l air pot. I’m watered without runoff with small amounts every day or if soil was wet than in next day. Today I was making flush with Canna Flush and runoff was 6.5 ph (light green liquid). My plant is from the start a little strange , it’s small , not bushy with small leaves and not much side branches but always was healthy look and now 32 day and last 3-4 days I have that issue with leaves in a middle of the plant some 3-4 leaves with strange orange , purple spots , yellowing and drying.
This is it , it was small and last two weeks starting up with central cola grow , light was in same place 60 cm above it , I think much closer can make burns or something this light is mixed COBs + 5w diodes in full power 620w. But now she stopped to go up , nothing new wont growing from sides , there is some sites like can be a new growth but nothing only some calyxes with pistils but nothing going from it
and no new branches or leaves.
Yes I was giving Sensi and another day Aptus.
