Grow QuestionsWhen do you stop giving nutrients?

When do you stop giving nutrients?

Mosherd7started grow question 4 years ago

Pictures taken 3 weeks into flowering. Its 3.5 weeks now. Started as pretty basic potting soil, most of the nutrients im sure are gone. When do you switch to just pH corrected water to feed? Thinking 1 more week for my yellowing plants, and less for my very green one. Thoughts?

Personally, I don't really stop feeding my plants. But the general rule of thumb is around 2 weeks before you plan to harvest. Since you're at W3 now, I'd say around W6,7, or 8 (depending on your strains flower time) is when you'd need to consider stopping feeding

Hey So outdoor growing can be a bit harder to call. For me, in the northern hemisphere most strains are ready between September-Oct and i stop feeding them in their harvest month. If your pics are 3 weeks old and you're already having good pistil coloring and shriveling...I'd peek at the trichomes but ideally start removing any nutrients now and finish out with plain water. I think that'd be safe for both the plants since were close to mid October. Happy harvesting. ✌️

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

Nutirents for hard water Question regarding the correct fertilizer amount. Advanced Nutrients. If my water already has a high EC of 0.75 I use less base fertilizer (Bloom A+B). But do I also reduce the amount of additives like Voodoo Juice and Sensizym, etc? Is there anyone here with experience with AN?

Adding P20 and K20 to a 8-0-0 and 0-6-12 A B I'm feeding Bionova Coco Forte A+B which is 8-0-0 and 0-6-12. I'm afraid my buds will be airy due to low P and K dosages. Do you think this will be the case? I was thinking of adding Bionova P20 and K20 to the schedule as she enters flower. Too much or should I go for it?
