Can anyone help diagnose this issue

[toolit4real]

so growing in ecolife soil and have had no issues until yesterday when plants were very droopy and lower leaves started to yellow so ive foliar feeded with some cal -mag and gave them a good watering as was bone dry, they have responded ok but was wondering if anyone can give me any tips on what the issues was, last 3 pics are of today and a close up of the lower leaves.

Are you feeding any nutrients also do you have any fans going? Picture 3 I believe it was looks like mold on the soil.

No nutrients as its meant to be the soil that has microbes that feed - the mould showed up when i applied a top feed of ecolife amendment, only a small fan

Id get that mold out asap as spores are easy to transfer. The new pics she actually looks pretty good. The tops looks yellowish I think because it's flowering. That very bottom growth dieing honestly looks normal as those lowest leaves usually die off. Let some others answer before doing anything though.

What's your watering schedule?

 

[toolit4real]

bottled spring water every few days as needed

Sounds vague....watering is often the root ( ) of many problems...

You have fabric pots, so you should be watering to runoff...which means they get all they need...not sure if you are going light because it's bottled (and therefore costly). Get into a pattern and stick to it...every 3 days is a good rhythm, and the plants will use what they need. This plan also prevents overwatering, which is much worse than under watering. Plus, with a schedule you can rule out "watering" as an issue
