I always add calmag to the nutrient mix . I have soft water in my area at 0.1 EC . I up that too 0.4 EC with calmag . Then add base nutes on top of that . Doubt you need to flush . Just add some to your nutrient mix .

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Why are my leaves turning this color?I scratched in 1 TBSP of Down to Earth AP (4-6-2) 5days ago with 2L of pH’d water (6.5). I believe I over watered as the leaves got droopy and then all of a sudden had a bunch of gnats. Killed them, soil is drying but now pale leaves and brown spots

Is it time to flush or wait a week?Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!

Yellowing Leaves? Nutrient deficiency? Fixable?Is this a nutrient deficiency? I'm 3 weeks into flowering. 2 or 3 weeks away from harvest. I'm using Biobizz Grow, Bloom and Top Max. Is it an issue that can be fixed? Or do I just need to get it right next time?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light SoilOn my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Yellow Spots on Lower Leaves in Week 5 of Flowering – Nitrogen Deficiency?Hey friends, I have a problem with yellow spots on the lower leaves. People are saying it's nitrogen deficiency. It's currently week 5 of flowering, and I'm wondering if this is within normal limits and if I should just leave it as it is. Any advice on what to do?
