Mo’Koko plant looks pretty bad. Most leaves yellowed up and died, buds have a lot less trichomes on them but bud size is okay. Not sure why the top dressing had no effect. Pro-Mix HP is doing very well. Good leaf colour, good bud sizes and trichome production. Added 4 tbs blackstrap molasses and some banana peel soaked water into 16L and will use that to feed them the next few days.
