I tried to follow the Muddy's life cycle, 11/12 weeks, this week will harvest the older plants, did the first flush on day 63, second flush on day 70 (yesterday).
I'm almost an foxtails expert lol... spent many hours reading about it...
Sativa strains carry it, is a defense mechanism for environments with high humidity, Sativa strains create foxtail buds to prevent mold but in the Indica strains mean stress... stresses that create foxtails:
. overheat
. over N at the beginning of flowering, heat excess will make the plant eat more N... N stimulates growth and P stimulates the fattening of calixes, over N at the beginning of flowering will make the plant grow calixes upon calixes
. over P in the last days of flowering
. not rotate the plants in the grow tent can also cause foxtails
. imbalances in nutrients, the difference between N and P is not appropriate, the difference between N and K is not appropriate, etc etc
. some Bloom Booster brands cause foxtails in some strains
In my case I have 8 autoflowers of 6 different strains, mainly Indica... 7 of them (5 strains) had the same problem, this was my first grow ever and I think I did all the mistakes that cause foxtails lol... if I do nothing I think the last plant (Auto Blue Mazar) will also have the same problem, I will try the tea, one tablespoon 1-10-1 guano and one tablespoon of humus to 4 liters of water.
