Oh No.. Does this image indicate a problem?

Indica strain in a 16 gal container outdoors for three months as of today. Noticed the curling leaves and purple/red stems last week. I had been watering every third day but someone watered for me every day for a week when I was out of town. I have the ph at about 6.8 and the nutrients are in the medium high range when I tested a few days ago.

The sativa clone with identical treatment does not have this..

Any thoughts?

Heat stress or over fert imo

i think your spot on with the heat stess buddy, im no expert and never claim to be but i've had a little leaf curl myself and doing alot of research on it, time and time again it seems to look like what you have right there..see if you can get a little more airflow going through and if it does'nt get better in a day or two, then it may be overferting but for now im going to say its just a little heat/light stress

edit: sorry i just noticed you said your growing outdoors, well if you can set up a fan outside that would do it but if not..maybe need to move them into a semi shadier area during the hotter parts of the day?

It never gets hotter than 90 degrees here and it is only getting about 6 hours of sun per day when it is not foggy.. I have been really hitting it with the nutrients though the past 3 weeks though.. Maybe I should just back off of those...???? Water everyday?
