nitrogen deficiency or burn? nitrogen is far less important during flowering but you always wanna have as healthy plants as possibly especialy during flowering obviously. as for the miracle gro i would get different nutes if possible, the npp is really high for marijuana and makes it really easy...
did you give your plants veg nutes? have your plants been under any stress recently? id say start at 1/4 or 1/2 strength in a few days and work your way up. what kinda nutes are you going to use?
iv always heard never to re-use soil and even if you could after doing everything you said, why would you go through that hassle when soil is so cheap and so easy to replace? sounds pretty retarded to me
forgot to add that i had a plant that started showing signs of flower about a month into veg with a 24/0 light cycle, never did understand how that worked but she ended up being my strongest and highest yielding plant that grow. embrace your eager girl!
plants look awesome! if your at day 24 now you should top them at day 28 and then veg for another week giving your plants some time to recover and making it an even 5 weeks of veg, should make for an awesome harvest and yield. just my 2 cents
pack on the nutes and molasses until the last week of your desired flower time then flush for the last week. its the best of both worlds, you increase bud growth and yeild while also getting the cleaner non chemical taste. btw nice buds!
depends on the strain, most ever strain i no of flowers in 8-9 weeks. its also up to you when you want to harvest, for example buds cut sooner will give a heady high compared to buds that are matured longer which produce more of a body/stoney high.
