if u r gonna use distilled water I would suggest you pick up some calmag for additional supplementaion. plants use alot of Mg and Ca throughout theri lifetime and many times just not enough in the nute bottles
call ur water company and ask them if they add buffers to the water supply-this would explain such a drastic swing in ur ph. also, that plant in the back in the first pic looks like she is going n deficienct early
u got something going here. these plants should look a deeper green and i can see the purpling starting on the leaf margins-these symptoms signify a nitrogen deficiency. being so young and considering already ferts in the soil, you should check the runoff ph and make sure N isnt getting locked...
wait. so can I or cant I use Cat piss for extra N during flowering?
all seriouness, nice post, somone needs to say it. should be in a BIG sticky labeled 'Etiquette'-Im sure that Johhny guy will correct the spelling.
ok looking at the new pic, indica is more like it. soaking up those amount of nutes in a short period of time will show burn in a couple of days.
flushing is good idea to remove the salt buil ups as well. Unless ur water is hard, over 250ppms, I would use tap b/c there is a small amount of trace...
man you gotta check everyday with DWC. it is the best method to grow with least maintanence but you gotta be vigil.
That being said, your plants look real healthy and somewhat happy. Being a dominant Sativa, that leaf curling and cupping is a sure sign of overfert. ur ppms are very very high for...
you wont really see trichome formation until the 5th week. smell from the release of terpantines more prevelant later in flowering. handle the plant abit and you will smell it.
judging by the two pics I would go with overfert over underwatering for sure. the plant is an overall very dark green instead of the lighter healthier happy color. those leaf edges could be nute burn or a calcium deficiency, hard to tell with those pics.
have you flushed the res in the past 2...
judging by the overall light green of your plant it looks on the verg of an n deficiency, waiting will worsen the plants condition. 1/4 strengt now should be fine. if you were nute burn and not deficienct I would say wait. but she is hungry. i would go with 1/2 strength
for starters they look healthy. I would venture to say that they are on the borderline if not already overferted. stop the nutes for a while. they should be a nice deep healthy green-ur are on the darker side. the tips of those affected plant looks like nute burn.
