I will start off stating that this is my first grow and I've gone through some issues and rookie mistakes; using MG soil and two plants, one pot. But I've kept these plants alive for the last 6 months and three weeks into flowering. I've noticed in the last week that the broad leaves are turning yellow and falling off. After reading, I'm guessing this is either a N deficiency, over watering, or over fert issue. Please take a look at the pics and tell me what you think.
What type of medium; soil or hydro?
What brand and type of soil?
MG - but the soil is about 6 months old now so I'm not worried about burn

What type of lights and how many watts?

Whenever dry, tap water left out at least 24 hours
What, how much and when was it fed? NPK?
Schultz Bloom Plus, 10-54-10
What is the medium/runoff pH and PPM if in hydro?
What are the temps and humidity in the room?
All within save ranges
What size pots?
Any bugs? Look real close.

Without a PH reading your just beating a dead horse:eek:. The PH has to be within range for plant to uptake the proper fert's at the proper time. Like i would guess Mag def and u try to correct it but in reality u r componding the problem because ur PH is off, locking out the Mag:smoking:

I'am no dirt guy,i think that's spot on only u want that reading from the run off water. To test soil PH start with water PH'd at 7.0,which is neutral. Water and ck runoff reading if it's 6.8 then ur golden. If it's to far out of wack and since u started with a neutral number you will know which way to adjust,that's the way i read it anyway,but i hav never had to deal with a plant longer than 3 months:smoking:
