Need advice from experienced autoflower growers on the effects of Cal-Mag deficiency and the effects of stressDo you think the plant will be able to produce a quality harvest after the effects of a Сa-Mg deficiency and a 24-hour absence of light? I had a sad experience when an autoflower experienced a lot of stress and produced a harvest with a weak effect.Other. Harvest - Smoking

Potassium, correct?I think this is the beginning of a potassium deficiency. The near neon green discoloration is what caught my eye. This leaf is affected the most.
Second week of flower. The Alga Bloom was just increased from 2 to 4ml/l earlier this week, so she should be alright. Right?12d ago

HESI grow scheduleHello, I have a question about this grow schedule. It implies that after 8 weeks your crop should be ready for harvest? However my autoflowers have taken much more time than 8 weeks to grow. More like 12 weeks. So how should I give nutrients to my plants? Also, I don't use clonesFeeding. Schedule

AN SensI Grow / Bloom A+B interchangeable?Looks like I’ll run out of Bloom at some point and I have lots of Grow left so wondering:
Since part A is 3-0-0 for grow and bloom, are they interchangeable?
Could I almost double up Grow B and get a Bloom B? 1-2-6 vs 2-4-8
I’m feeding at half mix rates anyways.
Or bad idea?

Nutrients first stageIs it my imagination, that the proces from seedling to flowering, is the most crucial stage of the plant. In case of adding and boosting your plant. What kind of nutrients could I use to boost specificly that proces? Or am I living in a fairy tale? 😉Feeding. Chemical composition

Nutrients in Co2 GrowsSo about the Nutrient Uptake in CO2 enriched grows. Is my reasoning wrong to assume that I should adjust my Nutrients somehow to compensate ?
