ProfessorNusters811started grow question 4 years ago

Hi growers! Just wondering how much Calcium and Magnesium is needed per Litre? (Coco coir nutrients). My water is very hard and contains 117mg per Calcium Per L and 6.5mg Magnesium Per L. Should I be supplementing my autos with extra? Thanks in advance!

Auto ultimate week 7 Enquiry Is everything OK so far? I'm thinking back left could do with nutrients? There is 4 here. Hoping for 60 grams each. I had 60 grams from my last one and that was natural, no scrog or lst or topping. Thanks everyone.

Potassium soil with neem oil and kelp extract as a foliar spray on seedlings I have doubts about applying some foliar sprays. I've used Neem Oil + Potassium Soap with some kelp liquid extract, together without any issues. The benefit of using it now is obvious, but, are my seedlings too small to handle foliar sprays? Could I harm them if I apply this mix?

我的女孩怎麼了，這個是生病了嗎？還是太多的餵食？在他長出第二對葉子的時候這樣的現象就出現了，但是只有一邊有葉子，我查了相關資料顯示這是菸草鑲嵌病毒（Tobacco mosaic virus；TMV）我覺得挺像的。但是不是很確定，我該繼續等幾天嗎？還是把葉子切掉。誰可以告訴我解決方法，希望他可以度過生長期，因為他是自動開花，每一天都很重要。

Advice?Done with LST. I added a little overdrive.. just so anxious. My plants seem in line with pics from other Growers diaries. Any advice appreciated. Sometimes I’m afraid I overdo it with early topping and I did a lot of lst on these. I’m new at this. Thanks for reading! 🌱

Good Nutrient Mixture For GH Flora My outdoors are transitioning and I got GH Flora Series (Micro, Gro, Bloom). I mixed 2.5ml of each into 1 gallon of water (4 L) and spread that across my 4 plants. I feel like this was too little? What is a good general mixture for 1 plant, or is it better to make a bigger batch?
