Pale leaves at the start of flowering

unless you are talking about 500+ ppm hardness, it shouldn't be an issue. hell, i've been using softened water for a few years now and don't see a difference. Didn't have to change my calcium levels in fertilizer, either. My unsoftened tap is 300ppm or less based on local water quality report. I think you have more than one deficiency. Possibly low S and Ca. I think that all mix is running low on nutrients. Start supplementing more and when the trend reverses, be ready to reduce if you've gone too far the other way... if the soil mix doesn't provide ca you mush... rust spots absent of interveinal chlorosis is Ca. interveinal chlorosis with necrotic spots is Mg. These are 2 different things. find a high-resolution leaf symptom chart and download it. You need more than just leaf symptoms to accurately diagnose.

Salam angrygrower! 👋 Welcome to the transition phase, Habibi! Day 36 is right when the plant hits the gas pedal for the "flower stretch." 🏎️💨 Let's use some Modern Engineering to diagnose this. You have two separate things happening here: 1. The Nitrogen Starvation (Pale Leaves): 📉 BioBizz All-Mix soil comes with exactly 3 to 4 weeks of food in it. Since you are on Day 36, the soil's battery is completely empty. Mixing 1ml of BioGrow into 3 Liters of water means you are only feeding 0.33ml per Liter. That is essentially just flavored water! During the flower stretch, she needs maximum Nitrogen to build new stems. The Fix: Increase your BioGrow to at least 1ml per 1 Liter of water immediately. 2. The Hard Water Trap (Rust Spots): 🚰 If your tap water is "really hard," it means it is naturally full of Calcium (chalk/limestone). If you have high Calcium, it chemically blocks the roots from absorbing Magnesium. When Magnesium is blocked, you get those little brown rust spots on the leaves! The Danger: If you buy a bottle of "Cal-Mag" and add it to your hard water, you will be adding even more Calcium, which will lock out the Magnesium completely and destroy the plant. 🛑 The Fix: Do NOT use standard Cal-Mag. If the rust spots continue after you increase your BioGrow feed, you only need Magnesium. You can buy pure Epsom Salts (Magnesium Sulfate) from the pharmacy, mix 1 gram per Liter of water, and water it in. This fixes the ratio without adding toxic levels of Calcium! ⚖️ Feed her a proper dose of her base nutrients, and she will green right back up! 🚀 Happy Growing! 💚

BioGrow is an organic 4-3-6 … 1ml / 3L makes 0.3ml/L … normally 1 (minimum) to 4 (maximum) ml/l is recommended. Cannabis requires between 8% to 12% of Nitrogen during Vegetative state and first 3 weeks of flowering. Biogrow (4-3-6) must be used with Fish-Mix (5-1-4) to make a 9-4-10 ratio. The rust spots are a Cal/Mag deficiency. You can use BioBizz Cal/Mag. «Ca/Mg deficiencies are common, as in today’s world we cannot rely on tap water to ensure correct mineral concentration...» (Source: https://biobizz.com/producto/calmag/ ) PH lockout is a myth…. I’m actually having issues due to a shitty bag of soil, the media was at pH 3.5 and is actually at pH 4.8 now, just look my last diary you will see …
