hey whats up fellow greenthumb.....

heres what i gather by your pics and info

#1 . you need more air than nute solution, plants are like us.... we need food, but we have to have o2..... time your drippers to flow for about 5-15min. every 4-8hrs and make sure your roots get plenty of air (w/o dryin out of course)

#2. if youre adjusting your ph from 7 to 5.5 at one time youre stressin your plants... it is advised in the "cannabis grow bible" that if you change your ph more than 0.5 a day, it puts a pretty large amount of stress on the plants, and what are you using to control the ph.... i just use lemon/lime juice with 2 ml. of h202 per gal. and ive had good luck with that

#3 i take it your using those 5 in 1 strips to test your nute solution... if so, the scale stops at 6.2 ph.. if youre pure yelllow, youre about 4.5-5.0 ... i personally tend to see my ph jumping around when i try to keep it low like that... it always wants to jump up for some reason..... i personally would keep it around 5.7-6.5

thats just my .02 though

keep us updated, id like to see the outcome of this

good luck:thumbsup:
