that 100W Fluorescent light is gonna be giving you like really really low PAR on the top of that plant. that is why it is growing so slowly, At that distance, it is not going to be able to give the plant much useful PAR to photosynthesize. Would you be alright with me giving you some pointers to help out? So if we are going to make it work with that light we are going to need to get it much closer, Just to finish this plant off then we are going to want to buy a new light. Fluro's can work fine for early veg if we keep them super close but they really will not pack the power for a solid flower cycle in my opinion. There are some VERY cost-effective LEDs out there you can get on amazon. Avoid blurple lights and make sure they are giving you an accurate wattage rating. For most tent growers 100-400W LED's are more than enough power. I see you are in a 2-gallon planter as well, That COULD be a little restrictive & root bound by now, Generally, we want to use 3 gallons for autoflowers. This might be attributing to the slow growth but I see now die-off on the plant yet. Cannabis plants love heat and humidity, The buds hate it. In veg we can exploit this for better growth if we aim for temps of 79-84 MAX & no more than 9 degrees less with lights off. It is important in veg and early flower to keep our temperature gaps close between lights on and lights off or we will trigger our plant to stretch more than we want it to. To better understand how important temperature and humidity play a role together please go read this article about VPD, Vapor pressure deficit & how it relates to cannabis growing, All new growers should learn this from the start. https://cerescann.com/importance-of-measuring-vpd/ I also suggest you get a PAR meter and a thermal temp laser gun to better read your plants and grow to their needs. This equipment helps us dial our lights to plant distance optimally and get the most potential from our lights. When we enter flower & get to around week 4-6 depending on strain, Autoflowers we watch for it by eye but at this point our plants have generally finished their vertical growth & have now focused on forming up bud. At this stage we can now begin to introduce wider temperature swings into our room more than 10 degrees less with lights off & our plants will respond by sending more energy into the budding process and resin production. When we are in flower we do not want our temps with lights on to be any more than 77-80 MAX. If our rooms are too warm we will get big airy buds with not much resin, If our rooms are too cold we go in the other direction really dense caked nugs but they are small. We want size + density.
