Late reply but for anyone else reading this; use buddy from week 3 to week 5, then switch to PK 13/14 for one week only and then back to buddy until flush. Do not use them at the same time. Also, I find PK 13/14 quite unnecessary. Buddy is highly concentrated and can be used as the only...
I absolutely agree. The trial should be replicated and peer-reviewed. This is still the most objective data I've seen so far on the subject. Anecdotal evidence is simply not evidence.
If flushing makes no difference, then you can save your nutrients in the last two weeks. They're really not benefiting from the results. You still made a valid point. You can't have a conflict of interest in a scientific study.
I've been flushing for 8 years. It's great to finally see scientific evidence on the issue. I still would like to see a test for the effects of molasses.
SUMMARY
Rx Green Technologies evaluated the effects of different flushing times on chemical profile, flavor, and smoking characteristics in Cannabis flower.
Flushing periods of 14, 10, 7 and 0 days were imposed on Cherry Diesel.
No differences were detected between flush treatments for yield...
So far the only side by side test I've seen was done by Migro. They claim the average yield of an HPS is 0.5 grams per watt and 1.0 grams per watt for a quantum board (Samsung LM301B). Do you agree with these numbers and where would you position a standard LED light?
I'm helping a few people grow so I decided to create a series of infographics rather than overwhelm them with unnecessary technical details. This one is a comparison between HPS, standard LED lights and the new quantum boards (Samsung LM301B). Can anyone confirm or refute the numbers, please...
The fact that it's in the top growth makes me think it's a calcium deficiency. Potassium deficiency starts at the tips and the edges and looks like a brown or red burn. A lack of calcium weakens plant tissue and leaves it more susceptible to heat stress which is why it affects the leaves that...
