Guano teas are your friend. Need some pk.
60 days is based on earliest possible harvest under optimal conditions and barring you had 0 issues during flower cycle. From what I know about WW it's a 77 day strain, not a 56-60.
It definitely
Its a Philips 250w HPS bulb, brand new when i put it in 7 weeks ago, used a Philips 250w MH bulb in veg stage. Im not sure how far away it is from the light my box is 65" H 27" D 36" W
So your grow area is 6.75 square feet. At 250w that is 37 watts per square foot. That's a little on the low side at least for me. I aim for 50 watts per square foot.
But, a small space like that would be hard to keep cool running 50w per sqft. Smaller tents are harder to pump 50 w per sqft and stay cool than a bigger tent with a proportionate increase in watts. It's counter intuitive because you would think that if I halve the size of my tent and halve the watts they both should be just as easy to cool. But that's not the case. Surface area does not increase proportionately with volume.
Something to know about small watt lights. Four 250w lights would not be equal in performance to one 1000w light. Sure they use the same amount of watts, but the par out put of smaller bulbs drop off quicker over distance than the higher watt bulbs. So most of that photoactive radiation is focused in the center of the light leaving pockets of insufficient light. So now the spots that get the most energy have to share that energy with the areas of low light. But....The act of transporting that energy (biologically) results in a loss of efficiency.
My first grow I got 0.5 g per watt with a 600w light. I'm around 0.9 to 1.1 g per watt running double ended 1000 w lamps. The gold standard is 1g per watt assuming you are doing everything right.
All in all, considering your on soil, small space, small light and that you haven't scrogged what I'm seeing looks about right. I would definitely scrog and super cropped next time around. Maybe even do some mainlining if you can get seeds because that would make it easier for the plant to share energy. But if you can upgrade to at least a 4x4 with a 600w light your first harvest will double the return. Some places offer financing, that's how I started. 12 mo same as cash, paid it off in 3 months. I think you will do fine. They look healthy.
