Hi @blendmedmedman! This looks like pH fluctuations to me. You should buffer your pH to ~6.2 which is the sweetspot for regular soil. Watering with the wrong pH will slow down or block nutrient intakes, leading to a slow growth / poor health of the plant. Get yourself a pH-pen, these aren't expensive but definitely helpful to get a successful yield. By the way, you should also buy an EC-meter, this will help you to manage nutrients and adjust your feedings to the plant's needs. Hope this will help, let me know in the comments section if you need further information. Happy growing! 👊

What are your ppms? If you're running 5 tsp of beastie blooms you may be over feeding. Beastie blooms is a super concentrated bloom nutrient, I'd start at 1tsp of Beastie Blooms and build up from there until you're comfortable. I know my last grow I was feeding the equivalent of 2tsp of beastie Blooms, 2 times a week.

If possible measure the drain for pH and EC, may be overfeededor a lockout caused by wrong pH.

Fan leaves curling up could be either high temps or nutrients burnt. Slight over fert to me so correct you feeding dosage. Be careful of the Male, the pollen sacks can open from a day to another and the pollen is light enough to travel far.

I think it looks like overfert or lock out. When the plant is given to much of one nutrients at any one time, it creates a lock out. Ph level of water needs to be analysed as too high or too low can make it hard for plants to absorb certain nutrients, just give her a couple of weeks plain watering until she looks healthier. 🌱💦Should recover
