Hi all
looking for some input on what’s troubling my girls
the two bigger plants have a lot of browning. I’m leaning toward overwatering. I water using Blumat auto watering. I’m not planning to do anything except get to harvest but I like to know what the community thinks for next run.

They are about 4-5 weeks into flower at the time of pics they are in Organic living soil in 7g pots.
I generally amend my soil before my grow starts, and at the beginning of flower I amend again with a bloom mixture, which is what I did this time
temp 75-77f day , 70-72 night 45-50% RH

Im running about 650-750 PPFD from my Photontek LED. I do struggle with light burn generally as I grow “sativas” and there hard to keep short enough.

any input is appreciated, thx

Looks like some sort of deficiency. Calcium?

 

[Gingerbeard]

Mid-late stage flowering deficiency. Annoying but normal.

 

[Bluey]

Agree with roots. Are you checking pH of inputs?

 

[Smallgrow]

As a living soil grower I don’t really PH.
I do from time to time check the soil ph and it’s always 6.5-6,8 so pretty bang on
Yes calcium was a thought I’ve been adding more crab meal to my mix maybe I need more or a different source

 

[Smallgrow]

Ya it’s a drag cause you know it’s taking away from the finish product so close to the end

 

[Gingerbeard]

Actually, the leaves are turning off and the buds are soaking up all the nutes. Just keep with the bloom mix.
You've been growing for a while. This has never happened?

 

[Smallgrow]

Hopefully you’re right. Its defiantly happened before , but I think it’s more than just fall colours and the leaves dying off
Just trying to up my game as always

 

[Bluey]

A few small changes can bring it on more or earlier or both, such as brighter lights or a change in the VPD.

Hi all, I grow in soil (black Swallow) one of my plants has developed this problem but others are unaffected, just curious if you have any idea what's going on? I am losing the big fan leaves because of this now

Thanks kindly

It's a calmag deficiency most commonly caused by too low pH in the medium.

 

[Rootsruler]

Cal deficiency usually shows up as crispier edges. I'm going to say N def. Could also be related to pH issues as mentioned by Bluey

How do I get rid of the bugs first time growing

 

[Rwise]

in veg I use spinosad, in flower if I must I use 1 part ISO with 8 parts water, both are contact killers spray the under side first then the top the soil everydamnthing. Do this every third day for at least 3 treatments.

 

[Bluey]

You appear to have spider mites

I've never had them so read below for a good run down.

If growing out doors I use neem oil. However once plants start showing sex I switch to garlic and soap spray. 4-6 cloves (or two heaping teaspoons of powder). Let set over night strain and add to 1 Gallon of water with 2 or 3 drops of the mildest soap you can find. If won’t eliminate them but it will dramatically reduce their numbers (re eggs). Be sure and spray underside of leaves. Only needs repeated after a rain or every 5 days or so. I would also suggest you discontinue this topical spray once flowering is fully underway. 👍🏼

Hi all
looking for some initial thoughts on this girl please.
She’s growing outside in living soil at a friends place.
I’m going to have a look this weekend and get some more details and pics.
This is all I have for now. It has been pretty wet and rainy here the last few weeks.
Any thought appreciated

 

[Bluey]

I've had this before but not to such an extent. I think it may be related to phosphorus issues. I'm pretty sure in my case it was not related to any pest issue. I had maybe a dozen of those circles on a dozen leaves at most and it went away with proper pH and nute management.

Hello fellow growers and thanks in advance for any help. This is my third grow and I have two plants in my indoor grow area; one is a banana purple punch (doing quite well, thank you) and the other is of uncertain genetics but was called Fem Autogrow Hi-C on the card I was gifted. The latter is the problem girl.

My setup:
1 - 100 watt generic LED full spectrum
1 - 200 watt Spyder Farmer SF 2000

Plant growing in potting mix in a 5 gallon fabric bag

Germinated on June 9 and has been in flower for about 12 - 14 days

Temps range from 72 to 78*F and humidity between 41 and 57%

Using Dyna-Grow/SuperThrive Foliage (during veggie time) and now Bloom at 3/4 tsp per gallon. I pH the water to between 6.0 and 6.4

Noticed some yellowing on a few leaves with brown spots, about 8 or 9 days ago and now it is nearly affecting all levels of the plant. Today I found some really scary leaves (see pic) that had curling and dry/necrotic leaf tissue.

I have flushed with plain pH'd water twice in the past 3 days but the ugliness marches on. I can't tell if it's nute burn, light burn, cal-mag deficiency or what.

Thanks again,
Allen
