Wedding Cheesecake Auto - 100 Watts

Hello this is week 8, week 4 of flower 4-5-6 weeks of flower are the most important because it's bulking phase, i have already see trichomes on sugar leaves are forming, which is a good sign! Wish me luck. Day 51 i did a small defoliation to open up the canopy for better light penetration and airflow Day 52 slightly lime green leaves on the top can be caused by low nitrogen in my water soo i decided to ise more Pro Organic Bloom nutrient, or it may can be just because of flowering stage, who knows😁 Day 55 plant is still yellow at the top, i don't know why, it can be either low PH in roots or nutrient deficiency, but PH is 6.8 at roots, so it must be PK lockout, i will stop using full disagree of Big Bud, for a few waterings. It also can be from genetics because i have seen many Wedding Cheesecake with the same issue, so i don't worry too much.
