Hey guys.
I'm going to start my 4th grow soon and although I got some top nouch smoke on my firts 3 I had lots of problems that so far couldnt really identify.
Some infos, 2.4m x 1.2m tent, 3 x 600w, tap water ph around 8 with 140ppms, soil grow (first 2 grows with biobizz, last one with canna quemical ferts), used ph up/down when needed and dolomite or epson when needed, temp rarely passes 30ºc, humdity arrond 50%, lots of air movement inside and good in and out flow.
The problems always started after I turned the lights to 12h, around a couple weeks after and they would range from red stems, yellowing of the leaves from bottom to top (progressing to the point of the hole plant being yellow), the leaves would start to fall, rust spots and slow growth. I have tried a bit of everything but nothing worked so far. My ph has been around 6-7 range, i normaly feed under the recomended doses but even if i do the normal doses the problems continue. Epson salt or dolomite have done nothing for the yellowing witch i thought cold be mag def, its not nitrogen def also because they get a good soil and regular feedings coupled with plain water feeds.
On the 4th grow I'm thinking of getting an ro filter and control everything that goes into the water.
Any help is welcome.
