Hi i could not find more information about yyour light// the lightdistance
, if she continues to grow very leggy withalong stem get the light closer and watch her-----
atm.. just dig some soil aroundd the stem to hold her and give her some airmocve / ventilation) to strengthen the stem... iam shaking my seedlingss daily, and let always let abreeze on them so that they are moving slightlly.....
hi i wwould start on 70 cm , and just let the lights where they are, and let the plants grow towards......
if your tent is not high enough dimm the light back if you are closer you can calculate wwith an X
that means
70 cm on 100 percent
50 cm on X Percent
drying quicker than other plants is another sign of root bound. I don't know if transplanting at this stage could cause problems but seems likely. just cut off Nitrogen completely, focus on bloom nutes and keep the light close to your plant.this might help.
