Sun scald. Where they well hardened off before transplanting? If so, usually the plant will adjust with time and while you may lose those leaves the plant itself should be ok. If not then you need to protect it for a few days with some shade and wind protection. Dave

Looks like an ivy (Hedera helix) to me too. They are British and North European natives which tells you the kind of conditions they like. This one could be something like 'Glacier' a hardy outdoor variety in the UK. It needs to be cool with plenty of fresh,moist air. Keep out of direct sunlight. Sounds like a challenge in the Phillippines when you could grow fabulous tropicals which we can only dream of.

Welcome to the forum, and welcome to summer vegetable gardening! It's a tough time of year for most familiar veggies, as you see. Humidity, heat, mildew, bugs. Did you see stunted, gnarly, bubbled roots on the plants you removed? That would be nematodes...kill plants quickly. The white squigly marks are probably leaf miners, not a huge problem unless there are lots of them. You can use the "search" feature at the top of this page to find past conversations about growing vegetables in Florida. It should give you a lot of info. Good luck and again welcome. Keep posting with your successes, failures, questions, observations, whatever. It's fun here on this forum! Treefrog

Pic isn't clear for me to see what I'm looking for so here is a guess... Do your stems have lots of black dots on them that turn into long black lines,eventually turning the stem black? If so I have some kind of sucking insect that seems to spread a virus that starts out as a bunch of black dots on the stem,turn the whole stem black-not sun purple. Sometimes it ,most times it effects only the branches the bug got to. I've had all but a couple branches get messed up and eventually die. If it's what I had,it doesn't seem to effect the branches without the bug bites.But the bug bites are not just 1 or 2 per plant/branch. The bug bites are a bunch at a time,close together. If it is a fungus,try Sulfur. Whenever I use Copper it seems to do more harm than good. There are several fungusides out there with 10-14% sulfur. Just NEVER use it with an oil or during the day.Spray it EARLY morning or sunset. If you use it withing a month of using NEEM or similar oils you can kill your plants(been there,done that). Oil reacts with sulfur to make a plant poison/Toxin under different conditions. I think some bug leaves a toxin that causes what I'm talking about since when it starts out it mostly effects the branches that were bitten. I've seen a plant bie except for a couple branches that didn't get the bites marks. Here is a link that might be useful: oil and sulfur
