they are in 4 gallon pots and they are still really small so i don't think they are root bound but they could be.

they have been in veg for over a month now so the stalk was getting kind of stiff, i was scared i wouldn't be able to tie them down if i waited longer. I will keep posting pictures. Let me know when you guys think i should tie down the other one.

regarding to ph
The soils pH started at 6 or something, so the plants were fine at first. After the third watering they started to droop, and after the 4th watering they began to droop even more, so i figured it had to be the water. The ph of my water was 8. The pH of my neighbors water was 8.7. Im not sure how that works out but i got accurate readings.

Ill post some more pictures once their light period starts again

thanks for the advice.
