Plant A has been consistently yellower than her sister tried to fix with CL mag Las week with little results just some burn feeding 3 times a day
Runoff EC :Plant A-0.7 Plant B-0.9
Just kept things the same this week. Feeding 3 times a day Keeping inflow EC about 1.3 to stay safe. The runoff of plant A got up to. 8 and plant B climbed to 1.2 with no changes just the occasional extra watering when the runoff doesn't seem enough.Trichomes finally! Was beginning to wonder when I seen how much further along the outdoor plants of the same age are.
Noticed some rusty dots on the leaves which slowly got a bit worse so I started giving some cal mag. Hasn't shown alot of improvement since I'm closer to the end I'm just hoping it's ok.
Just plant B seems to be suffering some calcium deficiency, I believe, I thought adding sensi cal mag to the solution at 1.5 ml/L but it seems to be getting worse. Is it not enough? If I were to add more do I keep diluting to 1.3 EC? Or should do a flush?
How's the pH? Raising slightly might help, but looks to be more than just a slight issue. Go to 6.3-6.5 in coco coir. 5.9 pH could be the entire problem, so i'd start there first as it's a fairly quick adjustment. This will help with Ca and Mg uptake.
Also, start calculating PPM you apply from guaranteed analysis labels -- even this time. It can help rule things out by simply typing values into a spreadsheet or online ppm calculator. i have a nutrient spreadsheet linked in my gd profile comment section, no guarantees it works for liquid nutes though.. .think i have it properly considering specific gravity?
if P/K are greater than 60 / 220, respectively and likely too high at each point, you might consider lockout to be the cause, at which point adding more Ca will only exacerbate the problem by locking out even more nutrients when Ca goes too high (not necessarily where you are at, but possible future outcome without enough info...)
had to re-write this after seeing the pH
