Any takes?

Any takes?

Thought I'd throw these pics out there. These just got sprayed with a Neem oil mix. Grown in soil. Currently under T5's. I believe the problem is in the soil mix. I am going to give them a kelp foliar a couple times to see if it turns/hilts the problem. If not then ill go to a alfalfa/kelp foliar. Ill also be giving a AACT sometime in the next week or so. Not as a solution but to make sure my Bennie microbes are present and ready to put these plants in the right direction.

I'd add about 2 cups of diluted Epsoma Lime for each plant. You'll probably need to water them with the lime a couple of times. Looks like you have the beginning of a Magnesium deficiency that's most likely caused by PH lockout. You might also want to try about 1 tsp of Epsom Salt per 2 gal water.

Hey mates!

I have this project going on:
They both are in a mix of 60% soil and 40% burned cowdung (not sure what the english word for it is) and watering with a medium dose of nutriments.

As you can see I have some problem with my plants. My newbie guess is that the plants got a shortage of magnesium or maybe they have to much nutriments?

I'm watering with a ph of 8 but that shouldn't matter since it's soil right?

Aloha,

Looks similar to what happened to my first grow. I'm using Fox Farms Ocean Forest, and no matter I do the nutes burn my plants. Raising the PH won't do much imo, but I do the best I can with it.

I'd do the same as I mentioned previuosly. Looks like nitro burn.

Hope it turns out good for ya'

Excellent thread Joe, thankyou for taking the time out to put it together

Hi, could anyone tell me what could be wrong with my seedlings, they are planted in levingtons number 1 but then I topped them with some guaonkalong soil mix, they are 18 days old apart from the tiny one.

 

[Maryjane grower]

They are getting pailer by the min, the ones still in the tent are fine, just these that I brought out :-(

 

[Maryjane grower]

I'm sure they are worse than a hour ago

I'm sure they are worse than a hour ago

put them in the shade...too much intense sun for such small seedlings...let them get used to the climate little by little

 

[Maryjane grower]

Thank you joe fresh, I hope it's not too late for them :-(

Zinc or Iron Def?

Zinc or Iron Def?

I'm having a wee problem after over-fertilization.

I'm growing 4 autos (Blue Mammoth) under 250w HID and in soil-less mix Terra Professional Plus growing medium. The temperature sometimes varies but usually is around 25C and drops at night to 20C-18C. However this is not an issue that I'm worried...

At 3rd week I have used vegie fertilizer. Half what was said on the bottle...but I feed them twice a week which was a mistake. I got nute burn...yellow tips to new growth. Done a half flush after 2 days from feed.

Now I'm in 4th week and they are getting to flower. Should I start feeding them with bloom fertilizer whilst they still shows signs of tip burn? Or wait for another week and let them burn all the nutes in pots?Or flush them again with fertilizer rinse solution like The Final Flush by Grotek?

Interesting thing that the plant with egg shells mixed with medium shown only little nute burn.

The biggest issue that I have is that one of them shows signs of Zinc or Iron deficiency probably due to mess up with ph.

My tap water ph is around 6.5. When I use neutral water 5.5-5.8 to get overflow my reading is 6.5...What should I do with this one?

Nute Burn


Zinc Iron Def?


Zinc Iron Def?


I will be very grateful for any advise and help. It is my first grow so I'm learning and the best way to learn is on mistakes...

What's wrong with my young plants?

What's wrong with my young plants?


Hi Joe,

Here's a recent photo of the top of my young Train Wreck strain.

They are in new, custom mixed coco-based soil. The tops appear somewhat skinny, but twisted. What's your best guess on what's wrong here?

These plants were transplanted from 1qt. pots into 5 gallon pots 2 weeks ago.

Daytime temperatures in the garden (full sunlight) are regularly exceeding 100ºf. And, yes they are getting watered daily, about 1/2 - 3/4 gallon each. They are being fed "Growilla" brand as a top dressing weekly.

 

[ExEcutioner]

nahh the burnt tips along withh the scorching is def nute burn....give them a flush(or plain water if in hydro.dwc) for a day or 2 and then resume...

Ive been a dumbass and i think i ruined my od season doing the above, and worse it was outdoors with soil crystals, the ground is moist and stays that way. am i best letting em dry out then water or do i try to flush so to speak?

its in the ground, mixed a bag of good soil in ground with half native. I roylayy fd up and used way to much house n garden a+b soil

Edit:

Problem wasnt house n garden. there nutes are amazing espically when u keep it 6.2 or 6.3 like they tell you. my problem wast N burn from strays pissing on the plants... problem fixed

Slow-to-no growth, help!

Slow-to-no growth, help!

Hello ICMAG!!!
Virgin post here, been lurking for some time.

Ready for the flames - here we go:

10 Unidentified bagseeds, recovered from flowers acquired as "ak47", if memory serves, soaked in paper towel May 7, first tap roots May 8, 2015.

9 germinated, 7 survive planting to 'pro-mix' (50-75% peat moss)
Been under 70-90w cfl, tried to keep the watering down. Had a fan on them for a while, but it was a bit direct.

This seems like very little growth for that much time.
The only purchases I have made are a bag of coco, but I haven't used it yet.


All help appreciated
