OK.....strain is Ice from 420-seeds. Plants are 23 days 12/12 under 400wHPS and 3 42w CFL for side lighting......ebb & flow 3x3' 1" rockwool in hydroton.....6 plants....all females....range in height from 22" to 28".......AN Nutes, full line.......had some issues with Ca toxicity (showed as K & Mg defic)...flushed with Clearex and did res change to remove Sensi Cal-Mag Bloom.......problems lessened and plants looked better for abut 5 days......then this AM I have several leaves gone yellow from bottom up about 1/3 of the plant.......looks like N defic.......checked pH....steady 5.7......TDS ~850......water 2xday for 15 min.......roots are fat and white....very nice....using Voodoo, piranha, tarantula and sensizym.....plants are producing small flowers already.......but I have this uniform yellowing from bottom up....I have had plants do this later in flowering...and a plant from a different seed pack do this same thing on my first grow......maybe it is strain specific......I dunno.......but it makes my plants look sickly.......the yellow is moving too fast for me to feel comfortable......any ideas.......I am not totally concerened, but want to correct issue ASAP just in case......two other issues are the res hase been cloudy last three feedings......possibly a bacteria from the mother earth tea organic I use, but I thought sensizym prevented that......the cloudiness has showed in prior grows,and usually always corrects itself in a day or two, so I was not surprised or anything, but the TDS has been rising for last 3 feedings.....went from 806 to 866 after 3 meals.....so coupled with the yellowing from bottom up, the cloudy res, and the rising pH I thought root issues...but my roots are awesome...they look like toothpicks.......just gorgeous, actually......and my other 3 tables are doing great, and plants have moved to other tables from time to time, and it only is on this table.......so any suggestions??? I am not worried, but I want to nip it.
I don't have any more ideas...so a fresh, and infinitely more knowledgeable, mind may help me....perhaps...perchance.......

P.S. Also, this AM at lights on, I smelled a musty/mildewy smell in the area, but it was gone within 15 mins of lights on...maybe the rockwool is molding.......although it stays pretty dry.....FUCK...I dunno.....I am sure I will still get a good yield.......I just want my plant to look PERFECT...and the just never do....LOL

Bump.....I had an idea.....could it be pot size?? I am growing i 6" nursery pots....I have used them with success many times, but these roots are MASSIVE......could I have root binding in my hydro system??? HMMMMMM........all the signs point to a root issue.........at least IMO..........so...maybe.....should I go buy some bigger pots??? I would shore like Al or someone who is a guru to me (Earl, VV) to help me out here....I am wanting perfection in all my plants, damn it!!!
