First Grow.

osmotic pressure causes the water to track up the roots anyway... sort of like how the end of a towel in water will cause it to "suck" up the water.. I keep my water flowing for water health/quality reasons.. Moving water is then sitting stagnant water.. Either way I'd recommend a high quality air pump..

Sorry i have to disagree with Larimar "I would say yes.......if its just a question of mathematics" uhm no that's not how that works and that's not how these ratios are determined. I can get into it , but long story short just use the florabloom at the recommended doses otherwise you'll burn your plants. Hope this helps ! 🚀

привет, друг! Да, это нормально. Растение заживляет свои раны. Но не в коем случае не пытайся убирать эти капли с растения! Некоторые опытные гроверы замазывают эти места специальными средствами, чтоб избежать заражения или болезни растения из-за этой травмы. Но если в твоем месте культивации чисто, стерильно, нет лишней влажности и нет проблем с плесенью, то эту рану растение без проблем перенесет. Все хорошо, бро! Продолжай свой рост! Удачи! 👋😇👍

That looks like a Calcium deficiency to me more so than a Magnesium one. If your PH is 6.5 I'd say it is too high for a Hydro grow. I'd recommend getting it to 5.8 to 6.1 so that both Cal and Mag are able to be taken up together. Since Calcium is immobile the plant can't "rob" it from older growth. Here is a good link that has the Botaincare Nutes image that will help you out. https://i.pinimg.com/736x/2b/b6/c4/2bb6c485409b6a2515024e8e91dfee2a.jpg
