LSF, cal/mad def, overfed or ph problems

[dabbler]

Hi,
I've been lazy and let this girl go as she looked OK but I'd like to avoid this next time if possible.
Shes day 56 in flower, she's had rust spots on the leaves and yellowing of the leaves also. The fan leaves end up crisping up and dying. Its a soil based grow (westlands plus) so I havent bothered with checking ph levels. I've given her epsom salts 3 times in her life

I reckon I have overfed her and I used black treacle instead of molases. I used bog standard feeds from the garden centre, a splash here and a splash there - not ideal I know, but its a ghetto grow

Here's a couple of shots that may help you help me:




I have another girl just going into flower and it looks like a similar problem in the making - any ideas?
Thanks in advance

Hey Dabbler,

I've got a similar situation, bagseed grow in soil, right now at about 1 month into flower. From what I've researched, iron or potassium deficiency produces this pattern of yellowing leaves with green veins. They can lock out together with PH probs, also.

Another similarity is that I have used a local product called Garrett's Juice, which contains MOLASSES. I've never used this product before, also I've watered with rainwater instead of our high PH city water. I thought perhaps I'd gotten the PH too low.

So far I've fed with some chelated iron on one feeding followed by a liquid fert containing 6/12/6. The leaves that exhibit the yellowing/spotting are mostly lower leaves, which jives with the potassium or iron deficiency, as these nutrients are slow to move thru the plant, therefore affecting the lower, older leaves.

I'm interested to hear what some of the more experienced hands around here have to say; I wish you luck.

Hey Shuffle,
I think it may be a lack of some micro-nutrients that are not in my feed. Its too late for this girl now but I'm going to try and get my hands on some worm castings as they are meant to have a whole heap of good stuff in them.
Fingers crossed for both of us!!!

Hi Dab,

I was sure hoping that one of the big guys around here would chime in an help you here. My girls are still flowering well with trichs still clear, as I earlier reported, abt 1 month into 12/12.

My soil mix is actually worm castings 50%, perlite 50% vermiculite 50%, not to dampen your expectations, but I thought you'd like to know that. Also, on the line of PH, that Garrett's Juice product is probably pretty acidic. Contains and smells like cider vinegar. I believe that this, with the lower PH rainwater that I'm using is key to my probs. Since this arose, I've been watering with half rain, half tap, which here is probably up close to 8, but I'm not sure.

The reason I changed the water and added the Garrett's Juice is that I've had probs in the past with too high PH, and lockout from that. I know, i should change only one thing at the time, but, well, you know how we are,,,

I don't have a digital camera anymore, so I can't take pics, but your pics are the closest to my situation I've found in a lot of research.

I've taken cuts from the flowering plants, lower limbs, removed the little buds and hoping for backup this way. I like the looks of a couple of them, there's just 4, and they are small; this is a very small grow under T8 floros.

Keep me posted as to your finds, I'd appreciate it.

Wish us luck and help from the smart guys. Where are they when we need them?

Dabbler?

Well, us low post count types don't get much attention around here; I'm dissapointed that none of the hot shots have graced us.

How's that for a whine? Mebbe too much Valentine's day wine for me tonite. Anyhow, here's a link of help from one of the doc types here:

I didn't see any pics that accurately mirror our deal here, but I did bookmark it as it is a great reference.

Other'n that link, I guess this post could be considered a bump.

Or a don't drink and post situation,,,

hey guys. One thing I have noticed around here is it gets pretty dead on weekends. people are out doing things. Now we have valentines day so hopefully............everyones out gettin some. LOL ! Which apparently I'm not.

Looks to me like ya got a bunch of things going on here.
1) Slight nute burn on the tips
2) Magnesium def.......The rusty spots between the veins
3) Phosphorus deficiency....The larger brown/ rust dead sections of leaf.
4) Yellowing is due to an N deficiency.

I must be honest and tell ya that I do not grow in soil so take my advice with a grain of salt.

Now, alot of this could be due to a PH lockout. I would suggest a meter of some sort. If you overfed like you think you did then you can lockout some nutes when overfeeding with others others.

You mentioned "laziness". Well.......You may have answered your own questions with that admission. . LOL. Not a dig. Just a suggestion to keep a vigil on the next one. Keeping a tighter ship will alow you to catch these things before they get extreme.

Seeing as you are on day #56.........are you flushing? This will cause that appearance as well.

Hope it all works out for ya. Hang tight. A soil farmer will chime in soon enough.

Hey Shuffle,
I think our friend pirate may be correct when he says its probably a PH problem.
Because you have all those goodies in your soil - I think that we either have a PH problem and/or salt-buildups. It looks like you have taken care of the feeding properly from what you have said so the only thing that we have both not done is check the PH.
I read and chose to believe that you do not get PH problems with soil grows - this may be our problem???
I'm flushing now until harvest so I will get the dying leaves on this girl but I'll invest on a ph meter and get all scientific on this next one and try not to be so lazy.
Any further comments from the guys would be very helpful.

Cheers

Hey Pirate and Dabbler,

Great to hear from an experienced grower on this; I hadn't considered a multiple cause situation here. Sounds plausible tho, as I haven't grown in years and I tend to find ALL the mistakes sometimes.

Anyhow, I'll get to work and see if I can get this fixed; the only thing I haven't tried is the magnesium deficiency.

Again, good luck Dab and THANKS PIRATE!

Hey no problem.
Before you go treating a deficiency.........(unless you know exactly whats going on)............FLUSH with PH corrected water and make sure your soil PH is correct. If your PH ain't right then adding anything will only make it worse. The mag might be deficient for a lots of reasons. Not necessarily because there isn't enough in the soil. To much of other nutes could lock out the mag. You need to flush and then verify your PH, then verify all the correct nutes before adding anything. There is no way to correct a problem till ya know where your sitting at any given time. Unless you get lucky. Otherwise its just guessing, and guessing usually leads to....................Posting in the infirmary. :smile:

Simple rule:
When in doubt......Flush it out.

Flushing won't hurt ya. But adding anything could.

Hey guys,
All i can say is PH, PH, PH. When i first started I NEVER cared about the PH of my runoff and used so many additives in my feeding program, my plants had so much lockout it wasn't funny. If your PH is off and don't realize it or correct it, you can add what you want, it only multiplies the problem. Keep everything very simple, ensure runoff is around 6.5, which works for me and be very careful of how much ferts you use throughout your grow. I used to burn my plants alot because I ALWAYS went by the bottle instructions for adding ferts. Most plants will burn and lockout at the suggested rates on the bottles. Start off by cutting your nutes in half and see how they respond.Remember each strain is different and needs to be fed as such. Make sure you use some sort of cal/mag additive and keep things very simple. As Pirate has stated, when in doubt flush it out and take your time. Once i started to pay attention to my PH runoff, my girls rewarded me like never before.One other thing also, did this all start in flower or did the signs also happen in veg? I like to keep my veg fert regime 1-2 weeks into flower which ensures a good N feeding and not cause problems. Hope this helps.

THANKS, Jazz and Pirate!

I came here to listen and now I've learned! Thanks for taking time for such a noob as myself; like I say, I've grown before, but this is the first in a long, long time and I guess in the past I was lucky (kept it simple) and the only prob I had was related to high PH; this time I think I went way too far the other way by overreacting to that old experience.

Now I just gotta get some tools together for the PH game. I'd never thought of testing the runoff.

Thanks, Thanks a lot.

No problem Shuffle,
The more you grow the more you learn and the better your growing technique gets.

Peace,

Take a spoonful of dolomite lime and put it into a 12-16oz water bottle. Fill it halfway with water and really shake it up thoroughly. Now fill it the rest of the way and shake it a bit more. Now you can apply it a couple different ways. I would recommend poking a lot of little holes in the lid of that bottle, and shaking it out like a foliar feed. Do this somewhere that messes are okay to make in. If you have a pump sprayer for your indoor garden, you can just mix your dolomite water in there. It gives you calcium, magnesium, and pH adjustment. Do this about once every 2 weeks and it will do wonders for your pH. With the right mix and this practice you won't really need to test pH anymore. You'll just know that this plus that equals such and such pH...

Hey Magic, Jazz, Pirate and Dabble,

Thanks all for your help and comments. I flushed everything today with PH'd water; mixed tap and rainwater; checked it with ph strips from my hot tub. 6.7

Also popped a pot and discovered that it is time to boot these girls to the next size. They are in 6" now, tommorrow they will go to the 8's.

I'll report the results as I have them. I believe at this time that I overreacted to old probs of too high PH from tapwater/SuperBloom by going with rainwater and organic ferts that were too acidic. BTW, I was unable to get good results today of PH testing the runoff, so that is still an unknown. These plants, bagseed as I earlier said are very compact, no stretch, got 1 1/2" nugs at this point (about 4 wks into 12/12) and looking pretty good, very sugary with trichs at this point. Changing to tap/rainwater combo seemed to slow the problem, a dose of N via foliar fish/seaweed and no more new yellowing, however the old yellow lower and mid leaves are still yellow, just not getting worse. (shuffle knocks on wood/head at this time).Wish I could give better info, but between my ignorance and lack of funds,,, well, I appreciate your patience.

Magic, I checked out your T8 cab. I'll be following your grow and hoping the best for you. I'm using 4 shoplights from Home Depot with a mix of cool whites and warm (8 tubes total, space is 2'x4'). The middle of March, I'll be planting out all the eggplant, tomatos and peppers and have another 2x4 area and the 3 shoplights servicing them in order to have separate, all floro moms and daughters at the same time.

Dab, how are you coming along? Hope you don't think i've jacked your thread, but your pics describe perfectly what I'm experiencing, and the help is overwhelming.

Hope everybody has a great week, and THANKS AGAIN!

Hi Guys,
Afraid its too late to do anything for the girl in my photos - I've been giving her tap water for the last week or two as I had presumed that I had overfed. I have another girl going into flower now so I will keep a closer eye on her.
Here's a few shots of the girl about to be harvested:
