Hello! first time grower and visitor of the growweedeasy forum.
I have no idea how to do this so ill start out with some facts about my grow:
Strain: auto fem Girl scout cookies from Seedsman
Soil: bottom half is biobizz allmix and top half is Biobizz light mix, both amended with Perlite.
water: i PH water between 6.5 and 6.8 every watering, i water about every 3-4 days and i always check that the soil is dry up to the first knuckle.
grow area: 60x60x180 cm grow tent
lights: spiderfarmer sf1000 that i run 20/4 on/off schedule
Nutes used at 1/2 of the recommended strength: Biobizz grow, bloom, Topmax, that is to say 0.5 ml /liter of water.
I did not use nutrients till the first signs of flowering. The plants are what should be their 3rd week of flowering but yellowing leaves have started to "crawl" up the plant starting at the bottom.
temperature varies between 22 and 27 degrees depending on the time of day.
My guess after some internet kungfu would be a nitrogen def, but there should be nitrogen in the Biobizz grow solution that i provide? My question is should i keep feeding them as i have, or is there more i can do to alleviate this problem? if it's even a nitrogen deficiency. Constructive feedback and idea's appreciated, stay awesome!
