strain that cant handle full sun?

Has anyone ever had or ever even heard of a plant that couldn't handle full sunlight?
I have a strain Ive been growing indoors that I really like, It has always done very well. Clones fairly well, tolerates abuse, dosn't nutrient lock when others do, etc.
I put them out this spring and it has been nothing but problems since then. All the other strains near them are fine but the one strain has continuous leaves rolling up and an orange-ish yellow spotting along the veins and on the leaves. It is worse on the south side of the plants and on the tops. Interior growth that is shaded looks healthy and fine. Leading me to believe the sun exposure is the problem. I have another little patch of random clones I tossed out that have the same issue with the one strain and not others.
The plants are clones of clones of clones that came from an outdoor plant from seed, perhaps they just became so accustomed to indoor life they cant adapt now?
I wouldn't worry about it but the strain is irreplaceable and it is an amazing hash producer. Ive taken some clones indoors to select a new mother from but I sure would like to see it healthy budding outside.
Anyways, can a marijuana plant be intolerant of full sun???

IDK for sure, but it's a good question. My litle brother has a plant this year that goes kinda half limp every day when the sun is on it and gets hot out. It's fine in the morning, but in the afternoon, it geta droopy. PH is fine and all else is well, it's growing but slowly. It seems it doesn't like the sun too. He is putting some shade cloth over it to see of that helps. He got some 50% uv block cloth. I guess we'll see what happens. I 've never ran into such a thing till now.

i no if u start them inside u are sposed to gradually get them used to the sun or they will burn....but i dont know if there are any that absolutely cant take it


just cuz i never heard of it doesnt mean it doesnt exist...

Yes some strains cant handle the sun and die when it really heats up. Keep that one indoor. Was it ever a good outdoor strain?

yeah the first year it did fine. Solar intensity is way up here in the PNW this year though. The sun hurts your skin on the days they dont spray the chem trails.

It is perfectly normal for all plants, trees, shrubs, weeds to droop when under direct sun/heat. If they remain so 1 hour after the Sun is no longer shinning on them, they are shy of water. If they perk up, they are perfect.

I don't think the actual problem is the Sun itself, in part. It's the cause & effects, namely, the heated soil & rapid pace of traspiration needed to compensate the increased amount of moisture required. Most of the Plant's energy will be transferred from the Veg & Flower growing to increasing the moisture flow. To compensate for this, a very large & healthy rooting system is needed. Seaweed is a rooting stimulator, use it every 7 to 10 days, 'outside' the perimeter of the roots to encourage them to seek & grow longer & bigger. With a healthy amount of Fungi, Bacteria, Microbial life, the plant can readily absorb the needed nutes & moisture. This will deter heat/drying out stress, that stunts the growth. Some plants have lived in cooler climates for 1,000's of years, so they suffer. Even Roofers has to aclimate each Summer. Dappled Sun in the middle of the day is good. Water way outside the rooting system to stop the DRY/Hot soil from absorbing the moist soil at your roots edge.
