Help my 2 plants are suffering.

[waktoo]

Yes they did, thanks for the reply.

Which was it, before or after?

edit, just checked my journal they started showing issues during around 30 days, so later veg, very early flower.

A 3 gal pot with most soils does not need any nutes added until flowering and then just once a week or so.

But I suspect your main issue is a ph related lockout so the plant hasn't been able to use the nutes you have been adding and it has been building up slightly.

What do you think, just pH water for a week? then back on the nutes ?

Sounds like a plan.

It's entirely possible that your soiless media is lacking sufficient levels of bioavailable carbon, rather than any particular/standard nutrient. Relevant to efficient microbial metabolic function, the role of labile soil carbon is very rarely, if ever, discussed. It is absolutely required for effective microbial nutrient cycling. I'll skip the boring soil science part and get to the remedy...

Try top dressing with 4-row (6 is OK, 4 is better) malted barley powder. It's a pre-germinated grain typically used for brewing beer. By weight, it contains a very large percentage of starch, and a consortium of enzymes that will break that starch down into its smallest molecular links, glucose. Glucose is one of the most basic forms of labile soil carbon.

For those small pots, I would suggest two tablespoons of finely ground malted barley powder scratched into the soil. Use a coffee grinder to turn the grain into dust. The finer the better. If carbon's the issue, you should see improved growth within several days. It should work pretty fast, but I can't say how fast, as I've never used it after things have gone awry. Heavily damaged leaf tissue will not fix itself. Reapply every two weeks up till just before anticipated harvest. It will not harm the soil, its inhabitants, or your plants.

Thank you for the great and full answer, you could well be right. Unfortunately, I do not have any malted barley or a coffee grinder.
I think there is some malted barley in pre-packaged form from a nutrient company, so I'll take a look into that.
Don't you think PH is the issue?

My Bluelab Combo Meter Plus arrived :smoking:, I'll check the ph of one of the plants I watered last night and check the ph of the other sick plant tomorrow after watering tonight.

 

[Don't Fear the Reefer]

So I took some soil ph readings,I took 3 reading and then averaged the 3.
The average PH from the Slaughtered Lamb is 5.36.
I also took 3 readings from another plant, which has just started showing issues and the average PH was 4.9
I will take readings from the sick Godzilla Cookies and the other plant I'm watering today, tomorrow.
Not looking good
What's everyone's recommendation now?
I'm definitely not using this soil again.

 

[Badfinger]

From what I have read, baking soda is a pretty quick fix.

 

[Don't Fear the Reefer]

Thanks Badfinger. I think it would be tricky to raise with baking soda as I'm using small pots and wouldn't know how much to water in.
Thanks for the suggestion.
I think I'll continue to Ph my water and nutrients and hopefully I can see this grow out to the end and get some smokable buds.
I'm definitely binning of this soil though, at least I've run out now.
