Is this phosphorus deficiency?

Platinum Huckleberry Cookies. Today is the 1st day of week 3 of flower. Growing in 1/3 promix veg&herb, 1/3 coco loco, 1/3 worm castings, with added alfalfa, kelp meal and oyster shell flour, also using gaia green 444 and 284 along with Dr. Earth's 4-6-3(was alternating with 444). In veg I top dressed every 2-3weeks and threw a tea in there.. First day of week 9 I flipped to 12/12 cycle and top dressed 50/50 ratio of 4-6-3 and 284 with EWC.. I noticed this purpling 4days ago before I left for the weekend. So early yesterday morning I started a tea using EWC, seabird guano, kelp, alfalfa, oyster shell flour and a little 284.. after 36hrs I fed the tea.. I'm fr a newb this is my first organic grow as well.. y'all think I did the right thing by giving the flower tea? Should that fix the purpling? The plant was not any shade of purple in veg.. I have accidentally watered until run off a few times so I may have washed some nutrients out if my soil.. all advice and criticism is appreciated in advance lol

It could be genetics which is normal, and yes it could be phosphorus but it's not a bad thing. Plants in flowering like the phosphorus.

Yea I get that they like the phosphorus but just wondering if it's lacking in P.. guess I'ma find out bc she definitely got a flower tea, if the purpling stops then I'll know if it doesn't I'm going to assume the best and hope it's genetics lol.. thanks

I usually get 15 percent runoff but I take my pot elevator down and set pot on the ground to suck most the runoff back up and then put the elevator back under my pots.

Ahh makes sense. See I keep them on my elevator so they don't soak it back in. I try not to water until run off though but few times I've gotten a good bit..

And if you think you have dry spots in your dirt dip your entire pot in good water until the air bubbles stop let drain for a little and put back into your tent.

You do see a lot of that color on this site. I really don’t know why. I can see in week 8-9 if it’s really cold at night. But for week 3 she needs something.

Consider week 3-6 they need everything as that’s the growth spurt. Let us know what you try and how it works? I suspect you need something water soluble to make available quick. Like fish stuff.

I definitely do have dry spots in my soil at times. I water with round up pump sprayer and I water as slow as possible 3Liters each time, they are in 5 gallon pots with straw on top to try to keep top few inches moist. I may have to try what you mentioned though. Is there a right or wrong time to do that?

Yesterday I fed a EWC tea with molasses, down to earth seabird guano, alfalfa meal, kelp meal, oyster shell flour and a lil bit(half cup) of GG 284. I let it aerate for roughly 36hrs

Update: it's been a week since I fed the bloom tea.. still seems to be purpling.. I was told this could be caused by consistent temps at night being 63-65°f? I was told that temps below 65°f make harder for the plant to absorb phosphorus. Apparently there is a lack of Chlorophyll being produced resulting in the purple shade? Any other thoughts on that?? I did get an ac 2weeks ago to bring the temp down for flower bc I was like 88-91°f with lights on and 78-81° with lights off. For past 13days it's been 75-81° with lights on and 63-65° lights off.. 2 other of my plants are starting to show very little purpling as well.

That explains it. Yep P deficiency due to cool temps. It's not really a big deal, but try to get the night temps up a little bit. It will give them pretty colors, but at the plants expense a little since it's doing that since it wants something that you're denying it.
