The thing that i like about this post is the dude has not gone into the counless do this do that that comes a long with growing,also the looking for a strain that can cope with a new growers,problems that he may come across.she is looking great nice coulour dude what ec you on,bump her up to 1.3.I will not comment on nutes because i have never used them i am a great lover of canna and advanced combo's.have you got a ec pen,borrow a ph pen and just take one reading if your water is good then that will do.I no longer ph,also i would take the way the plant looks rather than going on info on what you should be doing it looks good has long has your room is keyed,ie temps good good air flow plenty of movement and air been taken out the room and replaced by new has fast has possible.by this i mean i have a 10 " out let that goes to filter and inlet that is 2" smaller on the floor of the floor with holes made in the duct work,exaust up high.you can also start to panic when first growing with temps,thats why i have also gone into takeing at max 3 reading in winter coldest days i take a reading just incase i need to add a heater in the uk thats a defo yes,the other reading is on a warmish day in winter and the third just a random reading.i also do the same in summer but twice one reading on a hot day and a night time lights of reading,i do away with them after that for the reason that they can cause you to make stupid errors like changeing things to try and drop or increase the temps.if the plants look healthy then i just go on that i have 6 x 600 in one room with temps that reach 90/93 dgs but im a great believer that plants can become used to hot temps when i say hot i don't mean 110 dgs.i do flip 3 bat wings for 3 cool hoods in summer this gets me down to 28/30 i happy with that and so are the plants,this is another reason for doing true females and not femanised seeds,more chance of them flipping and giveing you seed.hope this helps.the reason my temps are a little higher in winter is bacause i have tested the yeild on cool hood the large ones not tubes there a waste space,bat wings are far better luman wise but my yeild is still good from cool hoods just about 6 oz less of two plants but 6 oz is nearly a grand.i have medical uses that relay on the medication that i grow for them so i like to get the most i can.Also the number your doing is great to see because most new to growing think the more you do the more you will get in the end nothing could be further from the truth.1 plant per 600 hps light will throw ya about 3/4 lb.growing can become a obsession and there is a lot to think about sometimes holidays have to be put on hold,also plants some times have to be taken down early or even at week 3 of flowering this happend to me a few month ago heart breaking.keep at it you will get there and you will learn far more by doing it your self........................tyke.................................................................................
