Nutes day done this morning, beautiful weather indoor 21C and 41% RH
Week 11 flowering... Thinking of chopping buds that have 80% brown pistils
She looks like a mess!
Me thinks that vegging for 11 weeks 4 sativas gonna be a challenge lol
If you have enough space you can make your own feminized pollen. How to below. The Colloidal silver can be bought at Clicks.

So I did a bit of Googling and seems the copper soap is not ideal and not recommended during flowering:

Seems Hydrogen Peroxide at 3% is what is recommended.
I have 4 x 5L containers, use about 10L water a day. Water stands for 24 hours. PH seems to have stabilized at 6.7 which is not too bad. Sent from my CLT-L29 using Tapatalk
Feed through out the veg and flowering cycle. I'm not bothered with seedling soil, I've been planting straight into the classic with no problems Sent from my G3312 using Tapatalk
This needs to be a sticky. This is Vital information and look you dont even need to know what V's from the C's. Thanks so much. Now I just have to make some PM happen...
Wrong time of the year in Joies for mildew
@LukeS the reason i dont like bicarb at a late flower stage is that it can get absorbed into the trichomes which will leave you with a harsh smoke & taste.
foliar spraying with lemon juice will attract WPM so its not a good idea, ideally you should be at about 6.2ph for foliar feeding.
the only real downside to H2O2 will be that you may loose some terpenes - this is debatable, but you will finish with good smokeable bud - i would still advise a bud wash after harvest. apply every 2-3 days. spray early morning before lights or just before they switch off & have a fan running. if you do this mid light cycle your plants will burn.
you can use the formula for diluting anything thats a bit tricky:
Using C1V1 = C2V2
To make a fixed amount of a dilute solution from a stock solution, you can use the formula: C1V1 = C2V2 where:
V1 = Volume of stock solution needed to make the new solution
C1 = Concentration of stock solution
V2 = Final volume of new solution
C2 = Final concentration of new solution
So lets say you want 3%(C2) final concentration & 1000ml (V2)of the final solution
You have 35% H2O2 (C1)
So:
35 x V1 = 3 x 1000
35 x V1 = 3000
V1 = 3000/35
V1 = 85.7ml
IMPORTANT STEP:
V2-V1 = water volume
1000 - 85.7 = 914.3ml So to get 1L of 3% H202 solution you need to add 85.7ml of 35% H2O2 to 914.3ml water
I do clones off clones. I have a big budha cheese cut for about a year now still doing strong no issues. Cloned it about 4 or 5 times already and I'm sure it's been cloned many times before I got it.
Just make sure they healthy before you take clones.
Maybe a bit late to reply but I used this guide, worked well for me: https://www.growweedeasy.com/cloning-made-easy
I was thoroughly dejected after my first couple attempts, as I had 75% failure rates, but it seems I was misting too often, and didn't let enough air in on the first few days; that recipe got me to 75% success.
