<span class="link_user">@miasmatic</span>, Yo, thanks. I've literally been doing nothing lol. Just turning the 100W light to 100 % and giving her some water 2-3 times a week. :D
<span class="link_user">@nomad_farmz</span>, They are looking fine today and plants need N even in flower.
Think the issue was solely caused by the fact that I let the soil get too dry too often. Which inreased osmotic pressure and that resulted in defficiency in lower leaves and excess in upper leaves.
I'll water more often from now on.
<span class="link_user">@nomad_farmz</span>, I appreciate the input. The clawing is why I lowered the dose of N by half and kept going with 0,5ml/l CalMag in yesterday´s watering.
I´ve measured the runoff (75ml) EC yesterday right after watering and it was 1,37 mS/cm. So about double the EC of the input. Though people say runoff EC is misleading while using organic fertilizers, so IDK what to make of it.
