Wilmaponicsstarted grow question 6y ago
Everything I read on pH for hydro gives different figures. Some say below 6.0 is to low. Some say above is to high. So which is it? Ive believed 5.8 is perfect but I'm still getting calcium deficiency even tho Im adding calcium. Now I read calcium cant be used below 6.2 confused

In hydro, calcium is best absorbed by the roots in the 6.2 – 6.5 pH range (in hydro, it’s generally recommended to keep the pH between 5.5 – 6.5, but calcium specifically tends to be best absorbed above 6.2)

All nutrients are absorbed at different ph levels but I've been told that 6.2-6.3 are perfect ph levels for soil and hydro to help the plant intake all the proper nutrients it needs.

Calcium is best absorbed in hydro at 6.0+. My feed always drops, so I like to set it at about 6-6.1 and then bring it back up when it hits 5.6/5.7.

All my readings and studies makes me believe she’s a female because of the white hair (pistils) around the top. Since I’m a newbie can someone take a look at the pics and let me know for sure? Also, how can I know if a plant is an hermie? It shows both sexes next to each other?Week 1

Possible rookie defoliating issueMid flower, defoliate, bad idea? Brought in more light and air circulation, but I’m thinking I might have stressed her out. Hopefully she will respond positively, what are your thoughts friends? If I messed up I hope it helps someone not make the same mistake by defoliating late

Is it normal to have different flowering times on occasion within the same strain? I believe yes as I have one that just grew one tall branch. So it focused on flowering sooner as it expended less energy on vegetation. She will be ready to harvest 3-4 weeks sooner than her sis.Week 10

Plants are 2 weeks old, approx 2 inches (5cm) tall in 3 gallon (11.5L) pots. I'm watering them with 1/2 cup (125ml) twice a day, and only around the base of the plants. Should I be watering 1 cup once a day? Am I under-watering? Do they need more water than what they're getting?Week 2

Hi everyone, anyone have any suggestions on when to put this little beauty into flower? I’ve never grown such a small plant and I’m not going for quantity here just quality. On one hand I’m thinking I could flower right now at 8 weeks but I also do not have experience mainlining.Week 7

Do I need to trim more?Do I need to trim more?
This is my first successful attempt, 2nd grow ever. First was a disaster (this one too, almost.)
I am petrified that I trimmed too much. But - when I see others plants, I'm questioning if I actually need to do more. Thank you in advance!
