hey maz bro,
the pic update is looking great! those nutes you added helped quite a bit, seeing a nice lush green color, no burn or curling, even growth... she's agonna be candy! i would also like to offer a different opinion if thats alright. i would maintain the light cycle on 18/6 for the duration of veg. i personally feel it is important to achieve good root growth and lateral branching and good sugar production in those dark periods, given the size of the pot you are using. a stable root system is key to stress-free flowering, and lateral branching kicks into higher gear after the tap roots have found the bottom. you're likely to experience more of this if you veg a bit longer. i have also seen longer light cycles cause stretch in plants of the same strain and i know you want to keep it short. strain aside, id say maintaining optimum light coverage and temperature control are your best bets in minimizing stretch. also, about when to put it into flower... a plant wont flower until it is mature enough, even if it is in a 12/12 light cycle. switching to a 12/12 cycle prematurely will kind of rush it into finishing up veg so that it can start the transition to flower. this can cause stress, which can in turn cause a hermi especially during the sensitive transition phase. a safe way to tell if the plant is ready for flower is to look at the nodes of your plants. right now each pair of internodes seem to be parallel with each other. when they start to stagger internodes instead of being parallel with each other, this is a sign of maturity. it typically takes at least 4 weeks. an issue ive noticed with seeds to watch out for, theyre leaves can get pretty massive, especially variants of indica. your 4 seeds look a lot like the master kush seeds i have. once they start fighting for space with their water and fan leaves, theyre gonna want to stretch big time... you might try and keep the big ass leaves tucked under the newer growth until you are ready to flower. what kind of plant are you going for? do you want like large single colas? some moderate nugs? lots of popcorn buds? were you going to do any training to them?
anyway just my two cents.... hope ur having a good week so far maz bro
peace homz
