I'm going to just pay the premium on ro water from the store for this grow, but when I do have the $$, is this legit? http://bit.ly/9pBGSF or should I spring for this http://bit.ly/cSWtQ5

it's definitely old school, salt barrel, tank, etc, so I guess I'll finish out this grow using RO water from the drug store. seems like my best course of action until I can fund a RO system... will the RO need epsom or calmag using the Lucas formula?

lol, I dont readily have a way of evaporating and condensing 3.5 gallons of water at a time, but I hear you

a joke right?

what can I use to rid the water of salt ions? clearex? I managed to recover the plant by changing the res again with just water + micro/bloom, propping up the major branches, and tying the two main stems with thread, but lost a few leaves (curled + crisp)

it has nothing to do with the water, I've been using it since day 1, this is over a month into grow, the entire plant lost all its rigidity within an hour

yes, please see the thread i linked, the plant was perfect an hour ago, and I just changed the res

omg. what just happened

wtf just happened. please see this thread: https://www.rollitup.org/marijuana-plant-problems/375997-what-wrong-leaf.html

well am using filtered tap water (not RO) but I believe my water is softened... are my calcium levels likely still too high?

ok, well I just swapped my res with pH 5.6 0-8-16/gal flora, 3ml/gal h2o2, and 4ml/gal calmag, hopefully that's not overdoing it on the calmag. Im going to start flowering either tomorrow or the next day.

yeah it is starting on the lower leaves first, I guess I'll dump my res and refeed with less mg, (actually I have calmag now, so I'm going to use that)... what benefit will peroxide have?

pH 5.6, 400w mh 18inches above plant, fed full strength lucas + epsom 6 days ago. Thoughts?

Positive its at 5.5, just calibrated my meter, and took a reading, roots are looking healthy, slightly brown near the top, but I'd attribute it to nute staining. I do not have an ionizer, just running a carbon filter in line with my exhaust fan. not sure exactly what the water temp is, but...

Hi I have a plant at about 2 weeks veg in a dwc bubble bucket under a 400w [MH] ~18inches above the top of the plant. I fed the plant full strength micro/bloom 5 days ago (lucas), and have added back in about a gallon of water since pH is ~5.5 In the last couple days, the plant's growth has...

Hi everyone. Just thought I'd share the progress I've made on my first ever grow. I started from a feminized hawaiian haze x plum seed about a month ago, had some nute burn problems early on, but am now in a nice veg, and plan on starting to flower in 10-14 days, depending on height/etc. I...
