    I wish more things were informative and straight to the point . Internet is now “hey just watch this for however long I can make you so I make money “ not with debacco these guys are the truth

    I’m having a really difficult time trying to figure why plant is not 100% healthy. It’s close, but something is off. I use general hydroponics trio but cant find a good balance for this specific strain. Will pay for help if anyone wants to zoom with me and help me figure this out. Please reach out.

    dark green leaves with brown spots on , any ideas what deficiency I have ?

    95% of the time ppl getting deficiency are because of overwatering

    My fan leafs new growth is showing that potassium issue. But it’s at the tip of the leaf. It looks like light green though you say yellowing. To me it looks light green maybe I’m wrong but that’s same color at the tips of one or two of my plants. How to fix issue ?? My plants are week 2 of veg

    I love your presentation and (while I know this is old) wondered if you could answer a question. First grow, realized my math was wrong and not adding enough nutrients. Starting to see yellowing of bottom leaves at week 3. To correct the issue I’d imagine I just need to have my formulations correct BUT since I just watered yesterday, is it safe for me to wait until the soil dries out more before adding in the correct solution OR should I do it now even though I’ve already watered recently and risk overwatering

    I need help with mine

    I like the quick visual guide but you should provide links somewhere in the description or comments to the videos. Like phosphorous deficiency-link calcium deficiency-link etc etc. I just tried to find your video that would further explain calcium deficiency and it’s a little difficult cause you have quite a few videos

    My plants are growing in a 3 gal pot in ocean forest. I usually ph my water/ nutrients at 6.3. At first the top leaves were just yellowing, now their having brown spots on the leaves. Can’t figure out what type of deficiency I got and how to save it.
