Fan Leave Going Purple the Day After Adding Molasses

ok, I'm just trying to see this correctly. You believe his purpling leafs are bad. You believe he has over done the ferts and should flush to correct it as you stated above ^^? NOT to flush pre harvest WHICH in return yellows leafs do to nutrient use up ( we both agree on this, but I believe to flush pre harvest and want to see my leafs yellowing). I'm right so far?

The thing is though, IF the prupling leafs are a problem( which I dont believe they are) THEN this is a P DEFICIENCY problem.

Not him over doing the nutes.

Therefor if anything he would be giving more nutes....not flushing.

But as others and I have stated in the thread ...we don't believe there to be a problem, and this to be natural.

I understand you don't agree with this, I still value your opinion.

"Phosphorus (P) deficiency:
Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.
Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.
Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals. "

.....and to me it looks healthy

I'm getting too stoned to make coherant sentences but i am saying to flush because he needs to one way or another, you think he should flush to harvest in a week i think he has problems with the plant and i can't quite make it out but with those ferts and that fert schedule or what i can see of one i think he has overdone it somewhere and recomend a flush to stabalise the soil and plant for the last few weeks of growth. I believe that bud has 2/3 weeks to go and have asked for bud close ups so we can all give our opinions. Either way a flush should do some good for all of our judgements on the plant and pics. I have tread carefully as after all it is his plant not mine but hope that what i have said has been constructive. Maybe i can find a few threads to illistrate both our points with the natural state of the plant leaves when entering the final phase of flowering. I don't deem this too be bad for a plant if it yellows or purples and it has done most of it's growing with just the final finish to go, even a sick plant will make it over the line but this is not nessecary in an indoor controlled garden and certainly not to the extent his leaves have gone to. My tomato plants fruit and grow and harvest without a yellow leaf, so do my jalepenos and they fruit and get harvested again and again. Outside in nature it is common to see but in an indoor controlled environment with good soil and good nutes, dosen't have to happen. And yes purple and yellow too are natural to some ornamentals, it just means that per surface area it wouldb't absorb as much light as a green plant but yes still it would absorb light and photosynthesis none the less just at a reduced rate, again this is very strain dependant.

Wow you never PHed your water AFTER adding tiger bloom?!?!?!

It's been quite awhile since I used fox farm nutes, but last time I checked it dramatically lowered or raised my ph (cant remember which one, I believe lowered though)

hey vantheman, your signature just made me shoot diet coke out my nose I laughed so hard.

Nope, I knew nutrients could lower my ph, I didn't have one of those fancy digital jobs to read it. The strips I have would have an altered read because nutrients change the color of the water. But my next grow will be a little different And hopefully bigger buds.

I wonder if addding a tsp of crushed lime would have made different when feeding? Oh well, I guess I'll never know.

for your next grow:

Only one ive ever used, works great...but cant replace the electrode.

or

Is there a better Ph up and down? In other words is their a brand that's more stable when making changes?

I buy everything from Amazon, already had the control kit in my cart.

I'm a amazon fan myself. I use the same ph up and down that you see in the kit, they work great, AN also makes good stuff, but more taxing on the wallet.

if you want a tds meter, I can say these 100% work, mine is usually off +6 ppm, but thats no biggy.

I can't afford a ppm meter or ph meter but flush after every few feedings and repot up reguarly, epsom salts is also known to buffer your soil as well as cure mag deficiency. Garden lime takes time to activate and start buffering your soil. Outdoor garden lime takes 5/6 months to work in the ground and the ground is limed in the winter, indoor finer grades are used and you can ground them down to a fine powder which will make them work faster, a way round this is to lime the bags of soil you intend to use in two months time to give it a chance to start working. When you add fertilizer to limed ground the ph will at first go down but slowly the lime will raise it and buffer it back to near ph7, this is why adding the correct ph solution to the soil is better than lime its just lime dose the job as well allbeit not as fast.

I want to bring this to light. I have been smoking purple strains since the early days of Led Zepplin. The origins of purple weed are a mystery . However, purpling is as natural as the changing colors on the leaves of trees in autumn, which is attributed in part to the pigment anthocyanin. Anthocyanin secretion is goverened by both genetic and environmental factors. Purpling is a simple dominant inherent trait.

Several compounds are responsible for color in plants: chlorophyll, carotene, xanthophyll, and anthocyanins. Chlorophyll is the pigmen that reflects green light. Plants use the energy absorbed by chlorophyll in photosynthesis to produce food for their growth and development. It is continually broken down during photosynthesis and being replenished by the plant. Carotene and xanthophyll are pigments that reflect orange and yellow light Both are present in the chloroplasts, with chlorophyll enabling the plant to absorb a wide range of colors of light and capture more energy. These pigments are present in such small quantities that the more dominant chlorophyll typically masks them.
During flowering, phytochromes, the light-sensing mechanisms in leaves, recognize the shorter day lengths. The shorter days and lower temperatures stop the chlorophyll from replenishing.
The molecules reflecting red wavelengths, anthocyanins, are water-soluble pigments that occur in the cell sap. These pigments may not be present during the vegetative cycle, but their formation is encouraged as the flowering process matures. During these days when photosynthesis and chlorophyll production are decreasing,sugar is mass produced in the leaves and also arrests the flow of nutrients into the leaf. The formation of anthocyanin requires bright light, a diminishing water supply, and the accumulation of sugars trapped in the leaf.
But King is correct, that this could be a P imbalance, but I do not think it is, since there is a fair calyx to leaf ratio, and the leaves don't appear to be curling up. My 2 cents, but as usual, I spent a buck and a quarter. Sorry.

By imbalance you must mean deficiency? seeing as it rare for it to be toxicity.

And if so, then why would you flush if it needs MORE P?

I would not flush. I believe that is natural anthocyanin production.
And , yes, deficiency.

This is gonna sound like I'm a huge dick head but

I'd change the "king" in that sentence to "lamb".

Ah, here is my other plant, the reason I thought it may be a pheno type is because of the obvious differences in the two. (I know it hasx yellow spots on the leaves, I used too much cha-ching) It's also much larger.

And I flushed it a week ago.

you should start flushing now they look ready so a week of flush now and you're good to go

i couldnt agree less, this is a perfect time to finish up with a ripening agent, i use a 1:5:4 ratio and do it for a feeding or two. he has another month to go. easily.

its probably purpling from temps changing between day and night or genetics.

Yes tiny i agree although it should be 'lamb is right' not 'king' although i am right about the purple plants being able to absorb less light that the green per surface area. The purpling here is due to stress and i think that yes the nutes have been overdone on both plants and look at the results!! A flush is what i recomended but only because i thought it looked stressed or deficient due to a nute lockout from either ph, over ferts and too many different ferts or somthing else. He still has a while to go in my eyes so can we have those closeups of the buds dude??

lol @ this being stress.

go outside in the fall and tell me all the colorful trees are stressed.

Sorry about that. We old geezers get confused once in a while. Must be my "sometimers" disease. Kinda like alzheimers, but just not all the time. Sorry Lamb. My bad.
