When should i start nutes on these gals? How about...

Once the roots pick up, so will she. Your pH is maybe a tad too high, I tend to do a water flush once every 10 days just to make sure the nutrients are not building up in one area. Wouldn't start feeding until growth has sped up, that's when you know you have good roots. Mychrorihzae is amazing really helps the roots alot! And a small bag is relatively cheap. 🌱😊

You need to start nutes now. She has a light color to her. In soil you have enough nutrients for the first 2 weeks autos can go 3 the most. For the strength start at 1/8 and slowly go up over time to 1/3 strength max. Autos do not require alot of nutrients like a photoperiod strain. They feed far less amount. Now for lst u really don't have any branches to lst yet wait 1 more week then lst. You can tuck big fan leaves out of way so you can get more light to the lower branches.

Your mix is pre-fertilized, it’s good enough to last around 4 to 5 weeks without adding any nutrients. All it needs for the moment is some root booster and some beneficial bacteria’s like mychorizae, trichodermas and Humic Fulvic acids. I do HST only called supercropping, I don’t believe in LST benefits. Defoliation, yes mostly on Indica’s as they tend to get bushy, but not necessary on Sativa’s.

Normally i would say... no nutrients needd before she is just before flower, But she looks pale,,, and dry.......Its great that you pay attention not to overwater her... but i would say water her nicely, then the nutrients in your soil will be solved and she get more gree... you can put her into your bathtub or shower and let some warm water run slowly on her and drain the soil more than now... then you have a good start to look if nutrients are solved out of the soil or not.... and if yu start giving nutrients the soil should be humid/ wet.... other wise the feedingsolution does not spread properly. So start in waterig her alittle more and look if she gets greener. Before saturate the soil well
