Brown leaf edges from transplant?

I transplanted my 5 plants yesterday morning from indoors to outdoors. Now when I checked on them this morning the perfectly healthy leaves yesterday now have discolored brown edges. Could this be from going from led lighting to getting sun from 8:30am to 5:30pm full exposure ? Or could it be from me using superthrive for the transplant? Or possibly the temperature change, they got a constant 70-75 degrees in the house to 70 outside during the day yesterday to 52 last night? Any info would be greatly appreciated

Looks like a combination of transplant shock and frying from intense heat/light, when moving from indoor to out its best to slowly introduce the sun for a few hours a day and slowly add a few hours every other day.

Also, make sure that bucket doesn't get too hot from the sun or it will quickly damage the roots, exposed plastic is a bitch to work with in sunny/hot areas.

That was my thought on it, people on another forum are saying Phosphorus def or cold shock.

Give them three hours sun for the first three to five days and increase one hour each day after that.

Could be UV burn. Move that plant into the shade and as SPLFreak said, slowly introduce them to sunlight. Start at 1 hour a day and increase an hour each day.

52f is for sure cold enough to slow your P uptake, but never have i seen a nightly temp of 52f+ enough to almost kill a plant in one night.

Put that plant in the shade or back under the led until she starts to recover, then re-introduce to pure sunlight but only for a few hours and work your way up.

Not sure how you transplanted? If your soil stays together while going into the new pot its generally okay, but when clumps start falling out or you hear little strings pop than you did some damage, i like to mold the next transplant with the current pot that way it slips right in with minimal damage.

In my state, under direct sunlight a plastic pot would fry everything inside in just a few hours unless it has a foliage or some shade above the pot.

When I transplanted I filled the 5g up and kept putting the pot in it to see where the cutoff was. When I removed the plant from the 1g it stayed together roots were crazy, which scares me because I really don't feel like having to transplant again later on. Then I hit it with some superthrive. That was all about 730am yesterday, it downpoured yesterday as well for around 30 min, it did the same today to.

Ouch yeah try not to let the rain saturate the pot just yet, manually do your wet/dry cycle untill roots branch out first.

Ya I wasn’t to happy about the rain, it came out of nowhere, then I was slightly worried about dampening off because of the rain and over saturation, but I believe it’s to cold for that particular disease to rear it’s head ? I’m going to keep a close eye on everything and cross my fingers that there resilient enough to get through it.

There is no way you'd have a P def that severe overnight. Most likely the sun was too intense.
