lol and you may have to supplement calcium and the magnesium as well. i know its complicating things but i think thats all you will have to change if you've always had good results. dont start over if youv done well in the past. just look at what has changed. and if its just water then, ro and cal mag will be your friends now.

its because soil is a buffer. its hit its holding capacity and now is locking out the nutes from your roots. im sure your new water is full of minerals and that is the culprit. or maybey its lacking cal mag. i dunno. but im sure its hard water if they are happy then not all of a sudden. its just a countdown to the day of locking up.

I think you've over ferted. ffof soil has fert in it. perhaps the sunshine mix does as well. to feed 50% is fine, however, it should be understood that in soil you may not need to feed as much over a long period. meaning, the ferts might be building up in the soil so now you have what looks like over fert. in one photo you have some yellowing/browning of at least one leaf tip when looked at closely, and this is usually cause by over feeding. to use a feed/water/feed/water method may not be the best thing as I've seen many people come to this forum saying they do this and now they have problems and can't understand why. if you use soil that has fert in it already, you really don't need to add much, until perhaps late in the grow. force feeding plants won't do any good. your temp at 85F is a little too warm for an indoor grow. make sure you have a fan knocking the plants around and moving warm moist air out. it also looks like your plants could use a transplant into bigger pots like 15 or 20 gallons each, if you going to grow them that tall. I think ideally you do this: grow them in small pots and up pot to larger ones as time goes on with the goal of using 15 or 20 gallon pots in flower. let the soil do it's job. it might not be necessary to add perlite or anything else. ff light warrior is really geared for seedling and small plants. then ffof for plants that are bigger, hard to say how big, but maybe 10 inches tall would be a good time to switch to ffof. use water only and let the soil dry out quite a bit between waterings. people can't stand this because they feel it's too simple, but then they add stuff and kill their plants. maybe it is this simple.

thanks for the input! I I turned off the co2, using a RO system ph'ing, and also decreased the temps to mid 70's. just going to use ph'd water and flush then see about adding nutes as needed after that minimally..
