GK-
only nutes that i have been giving them are the FoxFarms " GrowBig ", and i was giving them 1/2 tspn for 2 qts of water...
each plant got their own 2 qts, and they've each been watered twice since last saturday w/ the stuff...
i just flushed that plant, but the damn water wouldnt come running out the pot.. i drilled and cut at least 20 extra holes in the pot to allow the water to run out alot, and i had to let it sit over a sink and drain out slowly...

***i have 7 plants that look like they will make it to flowering, and out of the 7, 5 of them have this purple stems and branches, and yellowin up from the bottom up..... and like 2 of those 5, the new growth is very lightly spotting w/ yellow....
temps in the room are no higher than 82 and no lower than 77 throughout the day...
i bought one of those ph test kits for your water, and the guy at the grow shop told me that " my type of plants " like the ph results at a " piss yellow " color.. that's a ph of about 6.0...
i didnt make it super yellow, but just dropped it from a green, to a yellowish..

the ph meters i got to test the soil itself are CRAP! u can see both of them in the pics..
