ILGM sweet mix (autoflower)

Week 3 started good; I think. Girls look like they are doing good in my book. But I do believe I am under watering them. -Monday: I feed them 2ml of grow big, 1ml of Cal mag plus and 1ml of big bud. I was watering the girls almost every day before week 3 with only about 1 cup of water. So now that they are growing bigger, I think I’m going to give them up to a gallon for their watering since my watering schedule is every other to 2 days. I’m sure this is probably not the proper amount or schedule they should be on but it seems to be working. Haven’t killed them yet. -Wednesday night after work watered the girls with a little over 2L of water with the cal mag, grow big and big bud. Next watering I’ll be giving the girls in the 5-gallon pots about a gallon of water for their feeding. So far so good all of them seem to be growing well, Gelato 2 is a lot smaller than the rest due to me spilling her during her seedling phase. Just hoping she produces some nice buds. Since I am using FFOF as my soil I’m barely putting any nutes in for the fear ill burn the plants. -Friday: I decided to pull the trigger on LST the girls. Was very hesitant since this is my very first grow, I’d rather not jeopardize my yield and have my first grow be a bust. Decided to do it anyway. When I worked the main stem to bend it there was no cracking or snapping but the stem did have a film that started to shed from it. I don’t know if that’s normal or if that will eventually lead to shock and then death of the plant. Tied most of them down by the 3rd node, I believe they say do it at the 4th node but realized too late and didn’t want to keep messing with them since I already thought I was being too rough in my opinion. On an 18-hour light cycle that starts at 10pm- 4pm. Gave the girls a good watering after I finished to have them start the day right, Ph was around 6.5-6.8 with run off between 5.9-6.4. didn’t have too much runoff in the 5-gallon pots and I was afraid to water anymore since some of the fan leaves were touching the soil.
