I need help, plant has n ,phosphorus cal maybe mag
- Thread starter Micke930
- Start date
Its in Soil,ppm and ph unknown. it's 89 days old been feeding it canna terra vega during veg and canna terra flora in flower little less then recommended. Running 400w hps 2 fans. Strain is afghan kush special from world of seeds.
All I really needed to know is if this corrective elements will help me with a n or ph deficiency. I don't think it's mag or cal theirs no curling on the leaves.
its day 9 of flower the buds sites are starting to form/show
i just need to know will the corrective elements help the plant

It's common for the bottom leaves to start fading to a yellow once you go into flower because the plant is now focusing more on the new growth and the production flowering. In flower, you shouldn't be feeding it as much N anyways, the big green fan leaves have stored Nitrogen and the plant will begin to use the N to supplement itself. Post some pics. It'll be easier to help.
It's spreading it started at the bottom now moving up, it is a deficiency I know it's n or ph I looked up a chart the leaves are yellowing around the the whole edge of the leaf leaving the middle a tinted green or completely yellow and ready to drop off, their are also rust spots.
This is one of the leaves I took a pic of most are simular or worse. Theirs curling at the tips I just realised yellowing all over pretty much, stunted growth, purple fan leave stems
I am running 400w hps 2 fans carbon filter it's in soil I'm feeding it canna terra flora it's 89 days old,
it's been in flower for nine days I noticed some symptoms in veg and they progressed into flower
im thinking about buying surfer zinc mag and iron would that be the case? It's afghan kush special
ph and ppm's are unknown

knowing the ph and ppm are essential when you don't know what's going wrong.
the various nutrients will be available to the plant, or not, based on the ph in the root zone.
you may have a situation where the nutrition is plentiful, but the ph is preventing uptake.
after reviewing these images, i'm sure you'll agree that it's very important for you to get an idea of what the numbers in the soil look like.

You have salt build up. Your plant is clogged and not eating any nutes. You can supplement it all you want, but without the correct PH level, everything will start going wrong and your baby will die. Your PH allows your plant to feed, and from the looks of the picture, your plant is lacking N, cal, mag, boron, zinc and phosphorus. All which act as a domino effect. One falls after the other.

I can't understand why for the life of me somebody who apparently has a digital camera goes ahead and takes a picture of a single detached leaf... why not photograph the whole plant in it's environment, that would help us a lot more.
Trace minerals in and of themselves are not going to help a Nitrogen deficiency, where N is the limiting nutrient; you need to apply nitrogen. Anything with a good soluble N content will help: guano, a little blood meal, earthworm castings, or a liquid fertilizer with a decent soluble-N content will help. Soil pH is generally fine from around 6.0 - 7.5, depending on microbial activity and humus content. It is recommended to mix some lime into your mix prior to planting in it, about a tablespoon per gallon generally depending on your water source (use a bit more with rain\RO-water). Dolomitic limestone will provide Ca, Mg and neutralize acidity.
Most potting mix products are sphagnum-based or contain some amount of sphagnum peat moss, which can be quite acidic. Products often come limed, but the amount and pH of the product will vary and often they don't include enough for the long-term needs of Cannabis.

Thats make sense along with what urbanpharmer had to say,
also I grow in canna terra professional soil with canna terra vega / flora I would assume they have what most plants would need?
So if I invest in ph meter des tilled water, after that what measures do I take to correct the ph level?
what should it be between and how do I lower/higher it, I grow in soil and its afghan kush special if that helps
Sorry for newb questions its my first grow.
Please advise me on what I should do.
please an thank you
Soil PH is safe from 5.7-6.5, I would PH the water you use to water them down to your desired PH, and that will somewhat help PH your soil.
Canna nab terra does provide what you need to a minimal basis, but like I said, you won't benefit from any of the nutes, if your plant does not absorb them (PH must be right)
