Sensative Autos?

Hello everyone! My grow is on week six and I'm growing some very sensitive autos. They've taken 1 feeding at 1/4 strength and ended up with a little nute burn and nitrogen toxicity. They were also started in Fox Farm's Ocean Forest which is def a little to rich for the autos I've grown. But anyways, I'm 6 weeks in and just wondering if there're any tried and true techniques from this experienced community in which we all share? I've been just using straight PH'd water and since the last watering have added unsulphured molasses. On top of the recent chancge I've also added a 150 watt (50*3) LED... Just curious if there is anyone out there that would like to share any knowledge or wisdom they might have that will HELP a sensitive auto flower in its flowering state. It's obvious that these girls don't seem to like anything I've given them but water and poss a little LST, along with molasses (verdict is still out on the molasses, lol). I appreciate any help that is provided... Thanks everyone!!!

I'd say hit it with an epsom salt foliar spray every day for 3 or 4 days till it looks better and once you feel it's time to feed again go with 1\8th strength nutes.

Okay, I just finished 4 different autos.....heres my best advice, Flush your plants with 3x more water then you usually use. Flush, flush, flush! Ocean Forest and Happy Frog have been way too hot. This past year I have been dealing with soil issues. I have to mix with 50/50 (peat moss/perlite) to tone it down for my plants. Otherwise I cant feed them without stunting or burning!!!

Autos don't require much nutes at all to flower and how can you feed the plant any nutes if the soil is too rich? You really can't, so flush it(water should be almost clear), then give her bud mix at 1/4-1/2 dose when buds start. Increase the dose when you see her taking off...You will thank me. Do you have any pics?
