2 weeks after PMDD Ferts

This is the way my Hygro polysperma looked approx 3 month ago. Small leaves indicates nitrogen deficiency. The lower leaves started developing black holes and after that, falling off. Today my Hygro looks much better, but the leaves are huge. They are at least 3 times bigger than they were before. The injected CO2 and PMDD fertilisation must be doing great job. Yes, it is true that plants can grow without extra CO2, but do grow much nicer if added.
