Techniques. Defoliation grow question by BudHaks

BudHaks started grow question 5 years ago

When would you suggest, I introduce Canna PK 13/14? I have started to notice white pistols, that I assume is a sign that it's in pre-flower (refer to videos above).

What is the optimal PH, PPM, Humidity and Temp at this stage?

From the videos, do you see any deficiency?

Techniques. Defoliation

Hi @BudHaks! What a nice bush you got there! You can keep your relative humidity up to 55% for 2 to 3 weeks but you will need to find a way to decrease to 40-50% to prevent mold formation on buds. It’s best to slightly lower temperatures during the flowering stage, this will help in terpenes & resin production, 20-26 C° is the optimal range for flowering plants. Now about Canna PK 13/14, go for it, your plant will need P+K in the next days but also a slight dose of Nitrogen during the stretch. As long as you don't exceed 50% of what's written on the manufacturer's schedule you should be fine, remember autos are fragile and it's better to fix a deficiency than to [try to] get out of a toxicity. Hope this will help, keep us up-to-date and happy growing! :facepunch:

Hello ! Yes the 1st white pistols are signs of pre flowrer for an auto , that's mean you can start to use the pk in 2 weeks after the full stretch of the plant. The PK is for mid flowering but some starts to add it slowly since then end of the stretch and slowly increase the amount until the flush (it's up to you). Your humidity and temperatures are good for that stage. The optimal PH at that stage is 5.8 in coco ( its the sweet spot) in flower you can go to 6 PH (6.3 max) . The good Ec is between 1.2 and 1.4/1.5. From the video I can see a healthy plant but maybe a magnesium def (purple stems). I hope it will help you :v::grin:
