New Grower Same problem again :(

[joshua311]

Hi again AFN it's been awhile since I have grown. I have a plant it's about 16 or 17 days old and I am having the same problems as my last two grows. I still can't figure it out! Okay I am growing a northern lights auto and a white widow the white widow is doing awesome! The northern is the problem. Soil-ffof mixed with light warrior, 250 watt MH, temp is any where between 72 to 78 degrees, ph 6.5 runoff is a 6.4, I have the fox farm trio nute solution. Growth in air pots. Now I know this can't be nute burn because it happened when I was using a soiless mix (sunshine mix#4). The first set of leaves tips will turn a brownish yellow color and will start to decay and it works it way up to the next set of leaves. I am having really good new growth. I am stumped completely. I switched to a nuteient soil because I figured I sucked at sooiless mixes. I am allowing good dry periods in between watering. Some of the leaf stems are starting to get light purple. Not much purple but I can see it. Also I have not yet given the plant a feeding yet. Just some big bloom which reads 0.01 - 0.3 - 0.7

I dont think its burn.. How are you watering? Make sure those pots are paper dry before you water again.

Could be a slight nute burn but nothing to worry about Iwould not give any nutes for another week,than just a half dose of veg nutes.Tap root is growing down fast so make sure your pot is moist all the way to the bottom.

I watered this one to soon on my last watering but I usualy do the finger method and still wait a day or two

will do thank you for a quick reply. I was just curious because I even had this problem with the soiless mix.
