Hey guys!
Please help to identify what kind of deficiency is that?
Symptoms appeared a couple of days ago. Leafs’ edge became light coloured, then turned yellow. Both plants affected

- Watering: giving her water only. (6ph bottled water), 30ml once every 2 days
- Climate: avg temp 24C, rev hum 65%

It stands on bottle. Unfortunately I don't have a pH meter, that's why bottled water is used.
I think I'll get a meter today to get more precise ph level.
According to graphs I should aim at 6.4 - 6.5 level for soil, am I right?

Not all bottled water is the same...read the label, purified, filtered, distilled, RO......best to know what type your using
