I have a problem with my 2 week old plant. Leaves look burned. Sent from my iPhone using Grasscity Forum
Same thing happened to me a week or so ago with a plant, and now it thrives. Probably nute burn in my case. The top growth looks ok, and it will probably do well.
Light HID 150 W PH between 6-6.5 Temps range from 69-89 Flood and drain set up 2x2 tent Had setup for about 4 years. Last used about 4 years ago. Humidity???? Not sure Sent from my iPhone using Grasscity Forum
Your ph is too high. Hydro ph should be 5.6-5.8 What are your ppms/ec? Or what nutes are you using and how much in how much water. How often are you flooding? Are you flooding during light off? Also try and keep your temp swings at least with in 10 degrees. R-4808N
In my opinion just keep things simple. Use quarter strength fertilizer pH balanced until your plants are bigger and can handle more. Do this and your plant will end up fine. Your newer growth looks like it should so there's no real worries. J
