Re: New leaf folding
Pictures would help. .... With 116 deg F temps, ALL of the leaves will fold or droop in half. The plant has stop uptake of water. .... there are 2 reasons for this folding/drooping: Lack of water & high radiant heat (>100 deg).
A cup of 16-16-16 fertilizer every 2 weeks is not too much. But you didn't state what type of fertilizer it was (slow release or fast release water soluble) or how much water the plant gets and when. So water soluble fertilizer could be dissolving all at once and shocking the plant. Use field grade slow release granular fertilizer.
