My 1st Grow! Super cheap budget Grow

Hello Growers !! today is the start of week 8. day 50. This week we will be covering day 50-57, last week went well. hope for a great and easy week 8 as well. Day 50 they seem to have stopped stretching, and starting to stack buds, 🙏hoping for huge buds. and a great harvest 👏 I have noticed that the pots are no longer hold water like before. When I water I have to do it slowly. the water comes out the bottom of the pot.and its not staying in the soil, I have to give time to the plants to suck up the water. water was ph to 6.4, I gave the girls 30 oz each, and I have to water every other day now. 😟or they dry out and start looking sad, 😦 Maybe I need to use a bigger pot next time, I should from a 3Gal to a 5Gal. update for day 56 😱my ph in the soil is creeping up!! it's at 6.8 -7.1,😕 I am not sure why its move up?? I watered my girls with water ph to 6.3 hoping to help bring down the ph to around 6.4-6.6ph😕 if anyone knows what is causing the problem. please comment below or message me. Im still watering every other day, I see no problem yet, I will be starting the 9th week on Sunday5-17-20. thank you!!😀 everyone that following along, and help me grow !!😀 😁All my Girls are budding up and stacking up real nice!!😁 and the girls are starting to fill up the tent, 😊 🙏I was hoping for maybe 2oz🙏just to break even on supplies and electric🙏now i think i may get 3oz out of it !! feeling positive 😇😊 thinking of upgrading to a real grow light maybe the Mars Hydro Mars TSW 2000 for $300 and a 4x4 tent or a 5x5 tent, 🙏Hope everyone is well, AND HAPPY GROWING👊👍
