How's my plant look

Looks planty.

If using soil nutes, i'd go 2-1-2 ratio and if using soilless/hydro nutes i'd go 1-1-2... these generalizations need minor adjustments by observing and reacting to the plants. You probably need to do something more than 4-0-0, i don't think happy frog has a big charge of nutes like their FFOF substrate. check label to see...

Sieht toll aus, wenn du aber jetzt noch LST anwenden willst wäre jetzt der Zeitpunkt um die Triebe nach unten zu binden, mit viel Geduld und Feingefühl damit sie nicht brechen. Bei meinen habe ich auch nach dem toppen direkt damit losgelegt denn jetzt sind die Triebe jung und leicht biegsam. Nutze dafür einen Draht der nicht zu dünn ist damit sie die Triebe nicht verletzen.

my grow formula is 711

She looks really good right now after the topping. wait a little bit and help the tops grow outwards and the bottom nodes will catch up and you can do the same with the bottoms and that will encourage each node on your mains to stretch upwards and create strong even budsites

plants are looking good. however a feed of 4-0-0 is lacking in P and K N-P-K = 4-0-0 Also you will want to think about secondary macros Ca-Mg-S and micros like Fe,Cl,Mb,Zn exct Want to give them something a bit more will rounded like 4-6-9 or 4-7-7 the exact number does not matter too much. good N and higher P and K nothing to crazy high like 10-30-40 but some elevated numbers would help like in the previous suggestion.
