2 of my plants are in 4 week flowering and the other two are either 3 or 2 weeks in flowering. anyways, i've been noticing the bottom leaves turn yellow for a week now and so i thought it's nute deficiency and so i put nutes in. this was the first time i fed the plants so they got nute burnt quite badly. i checked the ph of the run off water today and it was 7.2??? is this a problem. i've heard it's suppose to be 6.5 in soil but other sources say that 7.2 in soil isn't that bad. Also, i've only been watering with water below 6.5 so it's not the water or the nutes. it's the soil itself. it is pre-buffered but on the pack it says the ph of the soil should be less than 6.8?! what should i do?
The pics show the yellowing.
