I think we’re doing well, have been letting the soil dry out and watering little and often, 300ml per plant on the 3rd day. Using a spray bottle. The smaller Malawi seems to be recovered. Watering using a spray bottle, used alga mic foliar spray. As always comments and advice is appreciated.
For your string, you can use cable ties to provide a loop around the stem then tie the string to the cable tie rather than the stem. I use hemp twine instead of string because it's not going to damage the stems and if any fibres get stuck stuck to the plant and end up getting smoked, it's only hemp instead of nylon or other man-made material! I also use bonsai wire instead of garden ties. No reason for this other than it's what I had originally so I stuck with it!
Hope this helps, good luck with your grow - their leaves are looking lovely and lush!
