Early flowering yellowing

[Cwmoore577]

Posted on August 27th about my issue. Plants are 15 days into 12/12 and I’m having yellowing and dying of the lower older growth. Assumed a nitrogen deficiency and gave a gallon (1/4 str) of GO BioThrive Grow (4-3-3) on the 27th, and half gallon of the same on the 31st. Still had yellowing so I gave it again on Sept 3rd (3/4 gallon at 1/2 str). Also, gave small bit of calmag with each watering. Still everyday there’s 2-4 more leaves that have yellowed and I’m wondering if I have a problem or is it normal? I’d imagine a few dead leaves is normal but not at this rate.

Are they burning through nitrogen in stretch and I’m giving too low a dose? Or could they be receiving not enough light?

Picture from Sept 3rd (tox curling is old)



Leaves from today


The canopy still looks good



Quick overview of my setup..
1x 600w full spec LED light
5 gal buckets using Fox Farm Strawberry Fields.
4 inch exhaust fan and carbon filter with a small fan at the bottom circulating air.
Temps usually 70-80, humidity unknown my guess is 50-60%

Ok thanks! I know that lower yellowing is normal bc the plant is sending energy up top to the buds, just questioned the rate. Seems every day theres 3-4 new leaves that have yellowed and fallen off. Is that a normal rate?
