Help! Plants turning black.

[Evilwam420]

Hey all! I've grown a plant or two in the past just to do it, nothing special. This year decided to grow to be set for the year and dropped some money on doing so. 6 different stains happening on 5 of them my iced grapefruit seems to be getting hit the worst. Growing in new England. Temp has been mid 80s during day and dropping to low 60s at night (for the next week going to be highs of 70 lows in the 50s at night) Growing outside in ground, using promix and the ff big 3 line up + cal-mag and beasty bloomz. Feed about every other day and water on most off days of not calling for rain or anything. Went in vacation begging on August and had a friend come water for me. Got home and noticed some of my baby/new forming buds were turning black. Checked out to try to diagnose and kept seeing the usual "mold, genetics, ph, weather yadda yadda yadda" after looking into each this does not seem to be the case. Wondering if anyone may be able to shine some insight as to what could be going on! Any questions please ask and I'll do my best to answer! Thanks for the help!!

I have seen this before but cant remember what the consensus was. It could be the purps depending on strain. Some strains will actually turn purple in lower temps (below 65F). I suspect that this is the case tho not 100% sure. https://www.growweedeasy.com/how-to-...es-turn-purple

The low temps at night is bringing out the dark colors. I grow indoors in my basement and winter temps get into the mid to low 60’s and the same thing happens. Certain strains are more prevalent than others. It doesn’t add to the potency but looks pretty cool

Lol it never gets cold enough in my house for purps. Dont think my roommate would appreciate me keeping the house cold enough for purps to show up.
