EC madness!!!!
mmmlovelytomatoesstarted grow question 5y 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

Adición de Blackstrap Molasses al programa outdoor/soil Biobizz- Try Pack (Fish/Bloom/Top Max). Cual es vuestra opinión?Is it harmful to mix blackstrap molasses into the Try Pack base Soil/Outdoor-Fish/Bloom/Max program? In what amount (liter/little spoon)? When should I use it? I don't think over-fertilization will happen, but will it be beneficial? I just stopped using Bionova after 4 weeks of Autoflower Supermix and before PK13/14.

I stopped giving my plants Plagron Silic Rock from mid last week (week 13, week 5 flower). Can anybody tell me if I did right to cut it in flower or does anybody has experience using this nute until the end of their grow? I think this nute is just for veg and early flower.

Nitrogen toxicity mid-flowerSo I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

Watering practice okay?When I water, I run 2 gallons of Ro water through every plant. I let them sit and drain for about an hour then I proceed to water them again, but this time with nutes (1100 ppm/6.4 ph). Let them drain, then they go back into the tent. Is that a waste or not? I have no issue.
