only water once the soil dries out and you need to start feeding. its probably a watering problem or nitrogen deficiency. those are really the main issues at this stage in the game. but since i have no idea what youve done to that plant because youve neglected to look at anything on this site...
um it all depends on height and size. for 4 big ones you might need a 400w hps or 4 tiny ones you could use a 150 or even maybe a 70w but id say a 250w hps and be done with it or use like 6 42w cfls with reflecters (thats the cheapest)
probabaly 2 weeks. nute burn is gonna slow the growth a little and more light would probably only hurt just hold tight for a little while and keep us posted
its probably nute burn the fox farms. you could try to transplant but in my opinion youd be better waiting it out they dont look to burnt to bad just a little. if it gets worse then transplant into a soil thats not so hot. also YOU ARE GOOD on nutes.... to good probably just wait
well id say about 10 days or so. once they get their second set of "true leaves" (3pronged pot leaf not the round cotyledons), they need more light but you can push it to 3 sets but theyll stretch a little.
I just dont think the technology is advanced enough in t5's or led to replace HID's. A 1000w hps cool tube takes up less space and would run about $200 new if you diy and shop around thats not even factoring in that if you live in the city you can go on craigslist you can get one for half that...
heres my humble opinion. they are bout equal. both can be used extremely effectively. However where my choice is made lies in price. HPS's are cheaper. for the price of your setup you could have 2 600w hps's atleast. maybe 2 1000w hps's. i wont argue about performance because i think cfls or...
not to be mean or anything but if you had spent a little time reading from here then you would know that the "small roundish leaves" are called cotyledons and they often fall off once there are larger leaves to replace them... if you are complaining about plant growth look around there is more...
thats fine im just saying its more likely youll get 1-2 females statistically speaking according to Mendel you only have a 1/8 chance of all 3 being ladies.
chances are against you not to be a downer. i strongly recommend purchasing genetics from attitude seedbank http://www.cannabis-seeds-bank.co.uk/ . even the cheap seeds are going to be superior to most bagseed. they are intended to be created as opposed to being accidently produced in an...
keep the shop light its weak but its still light. but cut the input where you plug other cords in you just want the male output of the cord and wire to wire into the sockets. then attach a y splitter into the socket to get 2 lights per cord
