Help- Deficiency

[Dr Pepper]

My plant has recently started showing signs of deficiency. Some of the brown was from the leaf almost dying due to a previous incident, but it is spreading.

What do you think the problem is, and could it be caused by high ph?
The plant is tiny, only about a foot tall, but currently flowering.
Please help!

Manganese? Calcium?

Need more grow info; but possibly due to ph it looks like..... what i your ph; what soil mixture are you using? How often have you fed and how much and what kind?

What lighting are you using how close to the plants?
What is the temps in your grow room?
What kind of water are you using? RO? TAP? Distilled?

Thanks core; sounds like someone did not take anyone's advice in that thread

Well it's obvious you did not listen to anyone in that thread about the big pots; why ask for help if you are not going to take someone's advice on fixing your issue? That plant needs a smaller pot you risk over watering you greatly in that size of the pot. It's rare you will see high ph in soil; you mostly see acidic soil. Did you even get a ph tester or test the ph this time?
You fed her at all? Why flower her if she is that small

Hi everyone, hi Stitch!

I believe this plant is outside under the biggest hps evah.....explains the flowering.

Ya know, that plant looked like it was recovering fine, this issue looks like N def for the yellowing leaf but i think it is just dying and fading from previous/current problems, and Cal def from the brown spots, prolly ph related. The bottom leaf was damaged before, but the yellowing has progressed,and there are more brown spots developing. I would like to see if there is a mag def showing up top....fading with dark green veins?

You've fed Fish poo every watering? Guanos and fishmeal ferts are very acidic, PowerBlend Pro included. I think there is the start of fert burn as well (some of those tips are really frying) from the high salts of the way strong miraclegro, plus the fish poo is pretty strong, as well. High ferts could be blocking your calcium, causing the spots.

Can we see some shots of the growing top, as well as the whole plant and pot? Thank you.

I'm inclined to think the ph is way low, but it only recently turned this way so for now just water with plain tap water, ph should be 8 ish if chlorinated with some minerals, and don't be cheap with the water, get good runoff...flush it out. That miracle gro is pretty strong and blech. You should be testing this runoff, but those pool ph kits with the drops are crap, a loose guess at best. Fine for your pool.......the coloured test strips are better, look for one with the most readings between 6 and 8. This should be most accurate.

but really if you are serious about growing.....

1. Lose the miraclegro and get into some good organic soil, coco recommended over peat. Add lotsa perlite, worm castings and a sprinkle of dolomite lime, to neutralize acidic ferts, etc and provide mag and cal. Your glorious and dank buds will remind you of your good choice everytime you smoke em. (hydro is fine for some, I am not dissing hydro, just miracle gro)

2. Use a quality organic fert like earth juice, biobizz, pbp or others and get dialed on feeding schedules and such. You need to learn your plants, your strains. You need to learn how to feed by "feel". Later learn to make teas and do it yourself.

3. Get a digi ph pen, doesn't have to be $200 top o the line, I paid $70 for a milwaukee ph40. You need to know ph all the time,and you need to see it to the first decimal point. Big diff between 6 and 7, ten times difference.

If you don't wanna commit to growing this plant and learning how, then you can expect failure. Sure, people luck out and happen to combine the right ingredients and get a good crop, but if trouble arrives......bam you are here talking to us instead of in your garden talking to yourself......fixing your own problems.

There are some basic techniques and concepts to master and once accomplished, you can grow any strain well.

PH is the first place to start and master. Once ph is confirmed correct then you can look elsewhere for causes of problems. Right now we don't know, as there could be ph issues and too much fertilizer issues together, but seperate problems.

Good luck.

Excellent advice heady

 

[Dr Pepper]

Thanks for all the advice!
Just a few notes:
I think the plant is large enough to be in the pot, i'll get some pics, (from above it basically fills the pot), and its upper roots are definately almost always dry. The ph being to acidic reassures me, since my water is ph of 7.0-7.2, and i was thinking my ph might be to HIGH.

Although i dont want to come off as a lazy grower, i don't really want to transplant this plant seeing as it will only have 1 month or so of growth left, and i don't think it will really be worth the effort, seeing as my current soil isnt the hardcore miracle grow, but a mix of the more mild "organic" ones as well as some normal topsoil and perlite, and i'm not terribly touchy about this grow since even with great growth the yield wouldnt be very good in just a month left.

Next year i plan on making a great soil mix using ffof, perlite, dolomite lime, castings, etc, (once plant is past seedling stage), and will make a grow diary. I appreciate all of the advice as it will hopefully prepare me for that grow.

I'll go take some pics, and water/flush with regular tap water (ph of 7-7.2), we are on a well so no chlorine or anything in there.
I'll do some ph stick research today.

Thanks again!

Ok, plant was flushed very thoroughly, the amount of water used is the big jar dealie in the back, over 2 gals i think. Took many pictures. Spilt water over keyboard so i have to paste "space".
1st pic shows scale , then leaves(problems), then top pictures, then side view, then a gnat i found in a top bud( searched thoroughly, only found one,i think it was high ), then a picture of a potential clone that i wanted to take but am not sure about due to flowering(let me know what you think, i want to preserve this strains as it is killer bud, and grow it out properly.) Comments are great, ya'll have been very helpful thus far.
Pics:

You want to pic clones before goin into flowering; reason for this is because stems are more woody and the clone has to revert into veg before growing decent size roots.

Not to mention you want to take lower cuttings from the plant because it does not have as woody of stems; if you pick a woody stem it will have a much less likely chance of growing roots.

You will know when you get a good cutting by feeling it; feels softer on the outside where a woody one feels like a soft stick.

 

[HeadyPete]

It's worth a shot to take cuttings...good luck. Take as many as you can, one may not make it to usefulness.

Honestly, now this plant looks pretty good, except it is behind for the outdoor season, and will probably not yield much, unless you are somewhere with a super long growing season or you move it indoors.

Well the sickness/dying doesnt seem to have affected any more leaves.
And i found the culprit of all the holes, damned grasshoppers.
Chomping away.

Oh, and backcountry, you threads are incredibly useful!
