Picture 4 this week. I know I had nute burn early ...

So essentially whats going to happen if you over feed in a soil medium is that it will retain for much much longer then say a soiless or hydroponic set up . With that being said if you noticed nutrient burn and then slowed down because you seen that you did well the only thing I would have changed is to feed it PH corrected water until the issue was resolved and not lower the dossages . To me your plant looks like its suffering from nitrogen toxicity , you wanna line up your nutrient solution to be more PK oriented because the formation of flowers is really really dependent on it in flowering . The signs for nitrogen toxicity are as follow's the leaves start to really darken and then the tips elongate and make a claw like effect which growers will call "Clawing". So for time being I would recommend that only feed with PH corrected water because to me there is still lots and lots and lots of nutrients in the soil . One thing about nutrients is that typically people wont start feeding the plant nutrients until its showing a sign of deficiency this way you can prevent over feeding leading to toxic levels . I hope this information helps you understand whats happening here and the very easy way you can fix it :) . I wish you the best of luck and your plants a speedy recovery ! -Happy Growing!
