usually 60 watts per square meter is recommended for good yields
Proper lighting is based on lumens not watts. (Recommended is 1000-3000 lumens per sq ft.)
Could try some, if any kick, then shorter to finish than starting over.
Not sure what this means. I don't speak the lingo.

(When I said "stretching" I also meant long internode lengths.)

As I said, for my other grows the lighting was too far away. During present grow the lighting was too far away during veg and most of flowering (Feb/March) then I learned how to get HPS closer about 5 wks ago (buds were already formed then). I've never had a grow where triches turned partly amber or milky which confuses me.

On previous grows I used lousy commercial nutrients. This grow I've used Foxfarm (plus some MicroBrew) from the start and Foxfarm potting mix added to black soil, manure, dolomite lime, perlite, sand in 3-4 gallon pots. Flower Lighting is not from the very top but slightly above the top and angled down @ 45-60 deg. (from opposite sides) due to low ceilings. (Veg. lighting was from the top and probably not enough light.) pH has been good throughout (6.3-6.7) and I've raised it once or twice with dolomite lime and flushed the plants once during stagnant growth (and yellowing of an AK plant) during flowering. Water is distilled and good ventilation. I get all feminized seeds from Attitude.

Pictured is white widow (open in new tab for better detail) w/haze in background (top fan leaves have yellowed and buds still growing). Thanks for feedback.
