blackberry kush , ffof , 18-6 , 2-spiderfarmer sf2000 about 16" up . Twmps 75 rh60.

Hello all I am in week 5 of auto flower kush . All I am doing is watering . I have ffof as stated . I have yellowing going on.
What do i need to do to fix this ? I was under the impression that the ffof would do me good pretty much all the way , but not sure. I do have mega crop and big bloom I can add to the diet I just don't want to over due it . Both plants are the same treated the same but only one is turning. I greatly appreciate any advise

I would feed with mega crop, 2g/gallon and see how it does. I have some plants that sprouted April 12th in 0.05-0.0-0.0 potting soil and have been feeding with 2g/gallon of Mega Crop and it's so green I don't see a need to up the dose, it's good stuff.

When a nutrient is considered mobile, it moves around inside a plant easily. Nitrogen is a highly mobile nutrient. Nitrogen deficiencies can be seen when nitrogen is pulled from older leaves, causing chlorosis (yellowing), to feed newer leaves. Other highly mobile plant nutrients include phosphorus, potassium, magnesium, chlorine, molybdenum, and nickel. When any of these nutrients become deficient, the symptoms will appear in older growth first....

FFOF begins a degrade about this time ( week 5-6 ) and can be recharged again either by a top dress , dry nute addition or comparable
feed. You can begin MEGACROP as you like , but rechargeable FFOF is the easiest. Especially since you are about half way thru a typical auto life cycle. ( week 9 / 10 for harvest ) . Remember autos will finish ( average ) within 90 days , so complicated feeds are not necessary .

Pretty much , water in 6.5 , then go have a beer. You didn’t say what your ph is ,,,, purple stems tell me something is off ( unavailability ) , try adding calmag at 1tsp per gallon to start or 2 tsp per for “ maintenance “ amount. Led grows tend to ” need “ it from time to time .
Yellow leaf will not recover.
