thnx waterdawg . I spend all day looking at images of plant problems and reading threads. I'm really in doubt between mag deficiency and nute burn.

looking like this today: I don't know what is going on , the Ph issue is solved. magnesium deficiency, nute burn, light burn? many thanks:peace:

thanks man . I searched and found that i need special license to buy sulfuric acid --- I bought today the general hydroponics ph down and hanna solution to calibrate my ph meter. I find out that my ph meter was 0.37 off :wall: just give a total of 520 ppm now... ph 5,8 and run off ph 5,9...

Thats great...Hehe Here in south america is hard to find that kind of products . its 80$ for both pH up and pH down. I'll order at internet and wait 2 months to get the stuff. Meanwhile i will pay $40 for pH down at my local shop.

I use lemon today cause its written on grodan RW instructions that i can use a lemon. The problem is... at my location the only weed related product i can find is GH hydroponics pH down but 100ml its about 80$

Thnx for comment! I search for info about my strains and found that WW and Aks are pretty tolerant to high levels of ppm and easy to grow too, but the OG Kush is not. I might do two feed solutions one for the ww and aks and another for the og kush. For sure i'll stay on the low side of the...

Ok a bad idea i agree bongsmilie I was reflecting about that , and this idea came based on al b fuct threads, the Al b. mums get no nutes till day 10, then they get 800ppm watering 1x/day, also he says: "I run all 4 of my flowering tanks at 1400, from go to whoa. Could go higher without...

My tap water has ~100ppm What i have in my mind is give that ~800ppm tomorrow and the rest of the week watering them only with tap water(ph adjust). The objective is ensure that they get the nutes right when the roots start to assimilate them. And ~ at the 15th day starts with a daily feed...

:eyesmoke: thnx ! i did it just for a couple hours with pH 5.6 ... if i adjust ph at 5.6 in my res. in less than 5hrs he is up to 6.2, so i decide to wait just a couple hour to use the rockwool after been soaked, that raise on ph is a normal thing right? the second pair of leaves is starting...
