Hello everyone, really sorry if I end up posting this thread in a few different forums/sites but I could really do with help ASAP and the more opinions etc the better.
I am extremely desperate to not lose my babies as marijuana is genuinely what keeps me going for medicine reasons. If I lose this crop or have a poor yield then I will genuinely suffer as this is the only source of medicine I can get.
Firstly a bit of info.
My background tap water is extremely soft water, no it isnt softened, just comes out of the tap that way. EC 0.1. on my meter.
Checked with the water board also, they report 25ppm calcium and 2.5ppm magnesium, total water hardness 30ppm , so VERY low, especially magnesium right?
Plants are about 3rd week flower in CANNA COCO with COCO A+B, no additives. They always have shown yellowing between the veins around the low/middle of the plant however during flowering its more noticeable on the middle/upper part of the plant. The only way to overcome that is running a HIGH feed ec, around 1.8 or more.
I experimented with a few different brands of feed and still get the same problems. Even with soft water specific. Problems always show up in flower. At this same time the runoff EC starts drastically raising up so I have to drop it.
I am now getting serious problems with the edges of the middle leaves, and overall all the plants are a much lighter green or slightly yellow with yellowing between the veins. Leaves are dropping off easily on the lower branches.
I am not sure if there is an issue with magnesium deficiency or potassium deficiency or even potassium overdose. I tried adding epsom salts and calmag but havent seen much or any difference.
Temperature 25day / 20night , humidity 60% , VERY good circulation and ventilation. All 2.4mx1.2m tent with 1600w lighting not too close either.
Any ideas anyone? I am genuinely desperate here especially as they are in a super critical period of flower....
