Grow QuestionsPPMs are running high during germination

PPMs are running high during germination

WeedDoctorSamstarted grow question 4 years ago

My PPMs are reading 600 in the DWC reservoir, which seems high. Tap water reads 380 normally. Doing a top feed system so the roots will reach the top feed tube in about 2 days if they germinate. Should I do a complete res change or just top up with pH'd RO/distilled water?

Hello. If they germinate? Are they still seeds? Seeds only need water till the first true set of leaves come up. Always charge up your water with oxygen, it dissipates chlorine and the plants love it. All the oxygen has been boiled out of distilled water, good for car battery's not for plants. So charge it up. Good Luck. Chuck.

Good PPM for feeding Autos, 2nd week flowering.What's a comfy place for me to be for PPM for nutrient feeding for Autos (2nd week flowering)? Currently for the chart I've been following I end up at under 400PPM but have been bumping it to 450. Can I go a little heavier?

Ensuring nutrient solution isn't too strong for coco Is there a way I can make sure my nutrient solution isn't too strong while I save for an EC meter? Should I just go off CANNA's chart and use the lower values? If anybody could point me in the right direction or show me a good canna coco chart that has worked for them, please do!

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?

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。
