What's up everyone? Ive been doing as much reading as possible but can't find anything that looks like it could be the answer to my problem. I've got some GDP from clone that I have never grown before, and just yesterday it started getting some purple on the top leaves and some yellowing of the lower fan leaves. The yellowing I assumed was an N deficiency, but the purple I have no idea. Here is some info on my grow to assist in your diagnosis.

Style: DWC SINGLE 5 GAL BUCKETS (4, BUT PROBLEM ONLY IN 1 PLANT. SAME STRAIN)

LIGHT: 1000W DIGILUX HPS 12/12

TEMPS: 58 AT THE LOWEST AND 75 AT THE HIGHEST. MOSTLY MID 60'S

NUTES: ADVANCED NUTRIENTS CONNOISSEUR A/B, BUD CANDY, BIG BUD, RHINO SKIN, BUD FACTOR X, SENSIZYME, VOODOO JUICE IN WEEK 1-2 AS WELL AS BUD IGNITOR IN 1-2.

ON DAY 24 OF FLOWERING



ANY HELP WOULD BE GREATLY APPRECIATED, PLEASE LET ME KNOW IF THERE IS ANY OTHER INFO YOU'D NEED!

Im guessing the purpling is normal but looks like your getting a lockout, I used sensi bloom for a while and it REALLY lowers your ph which cause all sorts of problems for me in promix. Was constantly getting mag lockout due to low ph. Conn is some strong shit, how much are you feeding them?

Thanks for the reply man, I thought it could be normal too and maybe the other plants will get it soon. Yeah after i mix all my nutes before i adjust the PH, its at like 5.2. but I bring it up to 5.7. Im giving them all different amounts, but this one takes the most nutes, im giving her 12 Ml per gallon of each A and B. Think that's too much?

lol, ya I would say you could possibly be overfeeding.. I think AN work very well but you need a damn PHD to get it down to the right feeding schedule. Don't go by calculator cause you will end up burning your ladies. Im pretty sure that the conniseur is alcohol based so it actually force feeds your ladies. Try backing off a little and think about getting some calmag cause to me it looks like your magnesium is getting locked out pretty bad

Thanks for the advice man. Yeah I already use Cal-Mag at like 3-4 Ml per gallon, but im gonna try to run my next res change at 1/2 strength in a couple days. For now I added some straight RO water to the res as it was getting low anyways. Hopefully it helps

Ro water, ummm I would run your plain water with the calmag added and no nutes.. I know when using ro water with AN's your calmag has to be at ATLEAST 100 ppm

60s is kind of cool. i've heard purpling can happen from cooler weather. is she outdoors 100%? is she getting a lot of sun? i think a flush isn't a bad idea. is your soil dry or wet? i think you need to give her a break. i find dryer is better than wetter.

Why is your room so cold? 65 should be the lowest and 75 highest without CO2. Max has you on the right direction and it sounds like you have kinda figured it out yourself Nice job!

On soap box I know you want the biggest buds but the hydro store saw you coming with all those additives not only adding a bunch of stuff you don't need it makes it more difficult to pin point whats going on. Off soap box.

Yeah thanks for the advice man, I wish I would have started off simpler and got more additives as I gained more experience. Im gonna lay off some of the nutes for a while and go with the "less is more" strategy until I know exactly what works for me. I've heard it was good to drop the temps into the 60's and 70's during flower, and it helps to dense up the buds. Is that not true?
Thanks again for your help

All I know is that when a plant buds it rips nutes from the lower leaves turning them yellow and killing them - I haven't grown that far to see what happens but thats what I have learned so far from the nice people on this forum.

Funny enough I have the same issue with a completely different setup, mine we're outside on 0-12-4 Guano and rainwater and my leaves look exactly like yours some purpling , others turning yellow, it has been frigid the last few nights so maybe that explains it. and the yellowing like you said is normal at this stage mine are 7 weeks in but I don't know the strain, what really gets me worried is that my other three plants are all really dark green still. does this mean they are taking longer ?
Is this just a strain thing? they we're all getting the exact same feeding schedule 1/week, only watering when dry, but it was all bagseed.
