Don't really get this girl at all. She is an autoflower. Prob about 2 weeks ago she started showing signs of nitrogen toxicity. I flushed her like five days ago and she still doesn't look amazing. I never had a plant do this before. She was in the dark, so thats why she is so droopy. She is droopy a little when the light turns on as well. Im not overwatering her, hell the other three aren't acting like her. Have any of you had this type of issue. She's in a 3 gallon pot, fox farm happy frog soil, no added nutes until I flushed her. She is soooooo annoying. She has signs of calcium deficiency, but that was prob because of the nitrogen toxicity.
I believe the necrotic lesions are showing a phosphorus deficiency, not calcium. Your root system isn't developed enough to sustain the amount and frequency of your watering regimen.
Phosphates will not be taken up if the substrate is too wet and/or cold. Also your roots won't grow well if always in soggy soil. Cannabis needs a wet/dry cycle to enourage the roots to grow in search of water.
It's very possible that this one seed is not as vigorous as the others. Seed bank are notorious for mailing F1 seeds, unless otherwise stated in the seeds description.
F1 seeds vary greatly in vigor and growth characteristics. If you want genetics you can count on, breed your own seeds and make s1 or bx. Or purchase them as such but be prepared to pay a hefty price.
Let this plant dry out, if you can get her closer to the light (hid, T5) the heat generated from your lamps will warm her and she will transpire more and help to dry out the soil. Do not treat every plant the same when your growing unstable genetics.
