Plant leaves yellowing! Please help!

Legolandon · Sep 26, 2011

I'm currently in the middle of flowering a Northern Lights plant that is under a 400w HPS light, and is in 50% Hydroponic beads 50% Soil. She has been yellowing from her lower leaves upwards and I would love it if you could help me save her! Here are the pictures:

I water her twice a day (considering that she is in beads and soil) and nute her with miracle-gro bloom booster about twice a week! If you have any more questions, feel free to ask! Thanks a lot!

twice a day is excessive. could be overwatering. that soil should hold in plenty of moisture to water once a day.

you should even practice a 3 day schedule.

Day 1 Nutes. Day 2 Straight Water. Day 3. Dont Water. Repeat

and dilute the nutes early in flower. i do 1/4 str for the first few weeks, then bump it up to half.

remove those dead leaves and monitor closely for spreading. It looks burnt so i'd go straight water and make sure pH is in range

its more likely to be a nutrient deficiency if ur using miracle grow. i'd get some good micro and some good bloom. before you think its a nute problem you should check the PH.

Thanks a lot! I will definitly try this, and see if it works!

I just tested my water run off's PH and it's a little past 7.0! I'll try to change that somehow. And I am using miracle-gro over and underwater protecting soil, mixed with a little bit of Jiffy seed starting soil, could this be a problem?
