Your welcome mate
4 gallon pot and vegging only 2 weeks = waste of space soil water and all that fun stuff one will need to note the roots will not grow that much once your in full flower mode
Yes they keep growing and its good to have space so you don't become root bound but the odd of that happening with a short veg are low
One thing i have noticed with doing a larger pot with limited veg time the plants
I find become more stretchy in flower and node spacing is very spaced If your using a Root booster you might be fine something like
canna rhizotonic as that makes the roots go nuts
Yes once you start seedlings off you want to keep the light away as you don't want to freak them out but once you have your first couple of sets of true leaves
can lower the light as they become light PIGS! using White light or lets say Metal halide will keep the node spacing closer
under a Warm light or HPS will give you longer node spacing
if your height is limited you want to make sure you flip your plant when your at 50% of your max as most strains will grow double in size and if this is the first time growing this strain your not going to be sure how much she will stretch just remember you can always do some (LST AKA
Low Stress Training)
It's a great way to start learning how to train your plant to bring out the most of your stain in limited space i would recommend doing all your training in veg
As this if your first grow and by the looks of things your doing well plant looks happy and healthy love your plant and she will reward you
All the best with grow keep us posted and if you need anymore help just ask and everyone will help but things to note
Things not to ask ...well you can! but only if you want the trolls to go nuts!
1) How much will i yield..
as a newbie what ever your total number of watts is you will most likely get 0.4 grams per watt
could be less could be more this is why its imposable for anyone to tell you
Is my plant ready...
Trolls will tell you 2 weeks every time! best way to tell is get yourself a 50X Magnifying Glass Jeweler Loupe they are cheap EBAY - Amazon pick one up for $5
http://www.growweedeasy.com/harvest That link will really help!
Sounds like easy things to ask but yes you will get smart asses
Things to keep a eye on when you start your nutrients once you see small burns on the tip of the plant that is your max at that point in time off the plant so lower your feeding by 10-15%
One thing i think everyone should do is test your run off at least once a week the PH or EC higher then what your feeding it make sure you flush or just on the next feed drop your level to 25-50% till your run off is the same as the level you want
Sorry for all the info growing is all about having fun but will never no it all so just keep reading and learning all the best with the grow keep me posted would love to see how she turns out!
