Zinnia and gladioli brown leaf problems

Hello,

Can anyone help with info/a solution for brown leaves on Zinnias and Gladioli? 
 
Here are some photos, both have been very healthy until recently.

1 Zinnias

I raised them from seed and they've been in greenhouse growing beautifully. 
I can't see any critters under the leaves.  I did water them a couple of times from above and wonder if that has any bearing on it?  




2 Gladioli

Possible thrips? Read about it never seen it/them!  The bottom of one of the plants feels loose as if the bulb is no longer holding it in the ground, as if the bulb is empty.

Thank you very much for any help and treatment suggestions.

    My zinnias looked like that, greenhouse grown, I just nipped the tops out to the next pair of leaves down,   There’s nothing wrong with yours, they’ll be fine soon, just pinch it off.

    Gardening on the wild, windy west side of Dartmoor.

    Thank you Lyn, I'll try that (when it stops raining 😁).

    Pull out the bulb of that gladioli and see if it has rotted off.
