Deficiency?

I'm not see much signs of deficiency. They are praying and looking happy to me. The light leave could just be from new growth. I would just keep and eye and see it the yellowing changes. If it does check the symptoms checker on I love growing marijuana website. It will at least give a a better idea of what it could be.

https://www.growbarato.net/blog/en/deficiencies-due-to-excess-nutrients/ excess of nitrogen blocks absorption of calcium, that drags magnesium and stuff, very simply - YOU OVERFED and have lock out of magnesium. nothing to worry, new grows looks not stripy , i would say few plain, phed water cycles without any food, just added 0.25 ml/l calmag and they should be back and ready for half doses of the things you want to put into them ;))) less is more in growing ! Good Luck !

I agree they to small to know 100% but look doggy and I'd keep close eye incase they hermie happy growing

Hi there At this stage its hard to say as there not much to go by .. i would keep an eye on it for now, only thing i would point out is the mature growth looks rich in nitrogen, Best of luck 🌱
