2.6/2.8 round these parts, $25 will get you 1.2/1.4 And $300-400 will get you an OZ

That may be the problem, undiluted HCI is very strong and contains Chloride(chlorine and plants are bad juju) ontop of that, too strong an acid dose(ie not diluted enough) can precipitate nutrient salts out of the water leading to nutrient lock-out(possibly the case here) H3PO4(phosphoric acid) is the best to use as it has very little to no ill effects on plants and is what's used in hydroponic PH solutions. If you can get it undiluted(%85+) it would be cheaper in the long run as you can make many batches with it.(never use any acid undiluted or diluted less than 1:2) Dilute at a 1:6-1:8 acid to RO/Distilled water, keep it stored in a cool place out of direct light in a black bottle if you have one. 1L will last some time. Remember to add you nutrients to your res first as they will bring the PH down some, then wait a few minutes before you test and PH down. Most nutes will bring your PH down by 1 or so, my tap water is 7.5-8 and after adding nutes my res is 6.2-6.5, then I use about 1ml of PH down(premixed hydroponic stuff, it's about 15% H3PO4) to get to 5.6-5.8 All good mate, hope the girls bounce back nicely[emoji106]

This should help aid future issues http://images.tapatalk-cdn.com/15/11/26/e55bc131943610a8b29edf8525c137a5.jpg Had it for ages, it helped me learn what to look for and what to do to correct micro deficiencies, may as well pass it round I'm sure we all need a chart like this[emoji108]

Woah, ok when you use the HCI(acid) is that straight from the bottle or are you diluting it first then using the diluted mix for ph down? The latter is the way to go[emoji106] (I do not recommend HCI as a ph solution though, just giving advice on your intended route) I suggest giving them the recommended dose for their age(may have to google a DM feeding chart) of Grow only and see how they go, I haven't used DM nutes except for add.27(good stuff[emoji106]) but I never had an issue with it. I have a similar air pump and it's awesome! Good choice[emoji16] The green is a good sign indeed

By now they should have their roots in the water and be big enough to be getting more than 540.. In my last DWC run, the girls were getting 12-1300ppm by week 3-4 and had quite the growth, it is all genetics and they're all different but almost any strain would have quite the appetite by week 4. What nutrients are you using and at what rates? Burn and deficiency can be identical and at this far into growth I can't fathom how she was burnt with 540ppm

All good mate, let us know how she goes

A few from the yard

Hey mate, Are you running any nutes yet? To me that looks not like burn but an N deficiency, she's just getting hungry is all, try adding some nutrients, 1/4 of the recommended dosage strength should be more than enough and see how she goes Those bottom leaves won't return to being green unfortunately but it won't spread any further and she'll be right as rain. Looks to be going good other than the deficiency, nice work

Epic stash NaychaCheers for sharing[emoji106] Nice line up dude, have you grow out any of that Coal Train? I'd travel overseas to get my hands on some Charlottes Web beans.[emoji16]

Anyone have anything new in the vault/on the way?

Those are some mighty fine flowers[emoji108] To edit my last entry, My mate and I were fairly high at the time and I miss heard what he said (stoners[emoji23]) so I correct the "BlackheadOGK" to DeadheadOGK

Straight out. Compared to other strains I've made BHO out of, this stuff hits harder than most
