I have a Indoor Grow, with 2x 400 Watts MH Blue Lamps, just under 3 weeks into veg, using Coco with Cork and Mills Nutes(1ml Nutes per litre of water), PH is 5.9, watering every 3 days. I have noticed a Rusty/Burny mark on two of my plants. Around 7 days ago the marks looked like the following And the same two plants now.(Looking better) What can be the issue
The ph is fine. You might want to think about transplanting them in to bigger planters. Sometimes we make mistakes when we water and pour some nute or water on the leaves. You're plants do look better now...the look of new growth and how its developing is a good a way to determine the plants health, but not always 100% of the time. Coco is great to grow in and I wouldnt grow in anything else...coco is hydro and one of the biggest mistake new coco growers make is underwatering/feeding. You can feed you're plants everyday without any issues as long as u have good drainage and you must always have runoff to remove built up salts. I can tell you the roots want bigger planters Sent from my iPad using Grasscity Forum mobile app
Hey, when you say "you must always have runoff" does this mean I must water with an amount that atleast something comes out the bottom? - If so, how much should come out the bottom? Maybe 10% of what I poured in the top?
Hey..yeah you want to have at least 10%. I would go for 20% myself. If you transplant...flush before you do. Sent from my iPad using Grasscity Forum mobile app
Not sure you should be giving any nutes right now. They are way too young.... Sent from my SAMSUNG-SGH-I337 using Grasscity Forum mobile app
