EC madness!!!!
mmmlovelytomatoesstarted grow question 3 years ago
About EC. Er...confusing eh? So, if I feed with 1200 and it comes out 2000, I need to lower the feed until it comes out 1600? And if I feed at 1200 and it comes out at 1400 I can increase? Right? Is the whole point of this to give the plant as much feed as she can take?

Yes it is to feed your plants from the top and know what's at the roots as well. For coco a ppm of 800, 1.6 ec is a good range for photo period plants. 600ppm 1.2 ec is good level for autos. If you check your runoff waters ph and ec level and their going way past that level, you know lockout is just around the corner so you run some plain water through to lower it back to acceptable levels. If EC is getting low you know to increase a little same with ph. Always stay in range for trouble free grows. Cheers

Ready for a flushing ?As I don't have any magnifying glass or microscope to check the trichomes, I'm relying on the color of the pistils to evaluate the maturity of the plants. However, as it is my first grow, I don't really now if they are ready for a flushing. What do you think ?4 years ago

C02 exhaust bagHi. I wanted to know if adding a CO2 exhaust bag in a small grow tent (60x60cm) is effective for overall growth? I'm European and most off my pairs said it was useless but the topics dated from 2010s and I couldn't find current definitive argument so... here I am.Leaves. Other

PH meter was wrongSo I learned my lesson by not checking the calibration of my PH meter. It was off by .6 and I don’t know for how long. The run off of my plants are right at 6.0. Using FFOF soil. Will it bounce back now that I recalibrated my PH meter or do I need to flush all the plants.Feeding. Other

Nute Advice - Botanicare PBP vs. KIND Full Range (Base Supplements).Thinking of changing nutes from @Shogun to @Botanicare for next run. Has anyone used the FULL PBP & FULL Kind range and could advise between them (Quality, Yield). Trying to work out the costs and if they're worth it (KIND range looks like £85/grow as opposed to £133 for PBP).Other. Other

Nutes mixing order??I’ve just read that you have to add calmag before the micros. I wasn’t aware of this specific order. My plants have been struggling, is there a chance that because I’ve been adding calmag as the last before pH, this is the cause of my issues?? What other problems can this cause?Week 4
