Afghan Kush SoG

Day 1 - This is my 6th grow so far. Any advise would be greatly appreciated. Germinated 36 Afghan Kush regular seeds. Planted in starter cells 2 days ago using fox farm ocean forest, so far 8 plants have broke ground. I plan on vegging for 3-4 weeks before flipping to flower. Day 2 - So far 10 seed have broke ground, are are growing steady. Day 3 - 16 seeds have now broken ground! I germinated 36 regular seeds (seeded from my previous grow) before planting. Today i turned on 1 small fan to strengthen the stems and added a humidifier to keep the humidity around 60%. They are 2-3 inches tall now. Day 5- Getting close to the end of the week and only 21 seeds have broke ground. I wont have as many females as i thought i would. A few are very weak looking and i will remove them later. They have started growing their second set of true leaves. I watered them today as they were looking sort of dry i used a mixture of RO water and 1ml of liquid seaweed ph to 6.8.
