Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Leaf spots issue Does anyone know what is causing the leaves to look like this? Throughout the whole grow i've had brown spots as you can see in the older pictures, although adding calmag didn't really fix the issue. If anyone has an idea of what this could be please let me know!

What have I done wrong and right?I'd love some critical looks at my plants, there are two in this grow. With only a few weeks left, I don't think there is much I can do to really improve things. But, please look at my pictures and tell me what you see wrong and what I should have caught. THANKS! 🙏

pH very low (5.0) but plants seem to appreciate it!!The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

Should I use a pH up -product?After mixing nutrients with my tap water, the pH of the mix is around 5.5. Should I use a pH -up product? Plant is showing a slight nitrogen deficiency. My tap water base pH is almost 8.0, but the Biobizz nutrients bring it way down. I am using 50% of the recommended dosage.

Cutting damaged leaves away or not?Hallo, I have some spots on leaves due to calcium deficencie and it has stoped spreading above leaves by adding calmag to the nutrient solution. We talk about 2 single leaves per plant (max 3 leaves). Should I cut them of because they need energy to recover or does it not care?

Friends need your help! the leaves turn yellow at the seedling stage!Friends, help me figure it out! First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom now I'll tell you how it was! after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0 drip irrigation works constantly! The temperature in the box is 23-25 C - humidity is 40-60% Inside, there is a fan on top that turns 360 degrees to blow the plants!

Nute burn or pH Flux Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.
