Yellow leaves

you cut to early your Nitrogen, ( week 2 of flower) its abig Plant and she had abig need in nitrogen to do the stretch maybe try some dry soil amendments like EASY BOOST OORGANIC NUTRTITION from RQS or the Product from Green house seedds CO or the Biotabs I tried them aall and you just give water, until she is flower . it eases tthe grow very much

The biggest problem I see is a 2.8 EC. That seems awfully high. You are probably experiencing nutrient lockout. Feed with just pH'd water for the next week or do a full on flush. Get that EC way down to around 1.8 or so, then start feeding again. If the runoff comes out higher than 1.8 after, then cut your feed back a little more. Ideally, you want the same EC in and out. As always, check your pH in and out to make sure you're in the right range. With an EC of 2.8, I would be willing to bet that your soil is quite acidic right now and your runoff is probably in the low 5s. If this is true, consider feeding with water pH'd to 7.0 until you get back up to 6.5 or so. Good luck mate!
