She’s starting to grow 😁

Sorry for the delayed response. I was on vacation. I think I replied to you about their feeding chart on another thread here on the forum. Doing a 1/2 or 1/4 dose according to the feeding chart is what many growers typically start at. Do you have a TDS tester on hand to measure PPM?

I run 5.8 pH going in every time for the life of the plant when in coco. What nutrient lineup will you be using? She'll probably be in that container for roughly 10-14 days depending on growth. You posted that pic 4 days ago; how does the plant look now?

Leave her in the solo cup untill she is much wider than the cup, then transplant into 2 gallon cloth pot . When she is wider than the 2, transplant into 5 gallon cloth.

I would revisit your research in the seedling-veg phase. PH in veg is a bit lower when growing in coco. 5.6-5.8. The PH you are currently at is typically what you will move to in flower. I would learn what your pot weight feels like when its full, then water when it's half the weight.

Are you using dry amendments or hydroponic nutrients? If you're making fertigation water for feed make sure you start the nutes at 1/4 strength and build up over the next week to full concentration.

you might want to try using these pots on amazon...search for: Orchid Pots with Holes Plastic Flower Plant Pot Clear Plastic Orchid Pot for Indoor.....with these you not only get good airflow to the roots but they are easy to not over water AND you can see the root system as it grows and you'll know exactly when to transplant.....
