PLANT TROUBLE

[bluntman2006]

What deficiency do you think my plant has.I use 12-55-6 neuts, I am thinking it is to much phosphate causing a iron deficiency. I am changing to 15-30-15. Is this a good neut ratio for flowering? I am going to flush with tepid water and then fert with miracle grow bloom booster, which is the 15-30-15. What percent of ferts should I use after flushing?
Phosphorus (P)
Phosphorus is a component of certain enzymes and proteins, adenosine triphosphate (ATP), ribonucleic acids (RNA), deoxyribonucleic acids (DNA) and phytin. ATP is involved in various energy transfer reactions, and RNA and DNA are components of genetic information.

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.

I am putting a pic of phosphate deficiency and also a pic of my girls.

for flowering, you want a higher second number, so the 15-30-15 would work, but I advise you go to any garden store and get something like Earth Juice Bloom, even Miracle-Gro Bloom, either would likely be better for the flowering stage .. :smokin:

sorry to double-post ... next time, do what I do, just for shits and giggles, ... I always throw a rusty nail into the soil, when planting, then you'll not be wondering if you have an iron deficiency ... beyond that, I'm not real sharp on nutrient deficiencies ... I almost never have ailing plants, and I never did much more than the rusty nail, and a weak dose of Miracle-Gro once a week, applied foliar-method, both sides of leaves ... hope that helps .. :smokin:

I wouldn't worry TOOO much that late in flower.. But then again, do I ever worry??

wow that is fried plants for sure. Way to much nutrients and in the wrong portions for the cycle. All you can do at this point is flush and flush.

I am flushing as we speak, would the 15-30-15 be sufficient fert for flowering? Or is that too much n/k2o? What are the correct portions for the flowering cycle?

They change each week. From the looks of your pictures I would not feed them any "N" for the rest of the grow for one thing.

There are some charts in the FAQ section you can DL and keep on your desk top.
