Purpling on leaves
Purple spots on leaves, leaf tips curling downward. Possibly a phosphorus deficiency caused by high pH?

Brown spots on leaves! To Flush or not to Flush? That is the Question.
Hello, Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

HOJAS MORADAS
Empezaron a ponerse moradas las hojas pero no se si será escasez de fosforo según lo que me estuve informando, o si directamente será frío. Esta en el mismo armario con otra planta y ella no se a visto como esta,entonces se escuchan las posibles soluciones !

Deficiency or Change to Purple?
started using the new “Purpinator“by Terpinator. Used Terp for a time and I trust the brand. That being said I have a weird thing popping up on my Dos Si Dos. Can’t tell if this is the switch finally happening or a Deficiency. Never seen a purple color show up for Deficiency.

Autoflower Selective Harvest?
Should I do a selective harvest on an autoflower? My plant overall is pretty uniform in height outside the main. Is it safe to harvest so that I can drop my light to give the rest of the plant the light it needs to finish strong?

Leaves with purple edges normal?
Leaves are now changing to purple edges and know that some strains just have different coloured leaves, but this has just happened later on now she's under the light inside and couldnt find any pics of super skunk with purple-ish like leaves. Normal? Stupid question probably!

Purpling of the leaves
Leaves starting to turn purple? I assume this is due to the colder temps I’ve experienced over the last week or two. As my high temps haven’t been more than the mid 70°’s and my lows have been down as low as the high 50°’s. Agree or signs of bigger issues?

Some sort of deficiency?
I'm thinking it's lacking phosphorus, but this is a first for me. I gave bio nutrients yesterday, which also contain phosphorus. I've read that bio nutrients need a bit of time to become available to the plant.... Any other feedback is also much appreciated

Leaves purpling?
Hello guys, Noticed some darkening on the new leaves, from the edges to the inside. I suspect the dark manifestation to be the result of 15-16c degrees at night. Run off ph is on point (5.9), 5/6th w flower, strain(critical either super queen) What are your thoughts abt it? Thx.

Small leaves, purple leaf stem and veins. Newer growth drooping
Second time this is happening. Plant grows beautifully until it starts to flower and then I get purple leaf stem and veins, small leaves and grow slows down. Exactly the same issue I had with my bubba kush. What's the problem ladies and gentlemen ? Temp day 25 humidity 45-50 %.

Nutrient imbalance or healthy development?
Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.

The insides of a small number of future bud sites are showing some strange purple discoloration. My initial thought was that this could somehow be mold however under the microscope it is very purple. Any ideas or suggestions would be greatly appreciated. (see images week 11)
