i have grown two auto and have a third in the tent now. its in ffof but in early flower they have all turned yellow and crispy after i fed it maxi bloom nutes. the other two ive grown did the same thing but with fofarms trio nutes. ph at 6.5 each watering. i have several auto seeds that where freebies and don't want to just throw them out. should you not feed nutes at all to autos? thanks for any info
I have only grown autos a couple of times but I did find that backing off of the nutrients does make for a more successful grow. The ocean forest is a pretty hot soil to begin with and if you follow the fox farm feeding schedule you can really nuke your plants. Even with my photos I am around half strength with my nutrients, now I have nutrients in every watering but in much lower quantities. It seems to work well for me. Try flushing your plants and then back off and see if they recover.
It helps me a little if I think of auto flowers as always in veg and flower up until the last couple of weeks because they seem to be doing both and the stretch doesn't really stop until it gets close to the end. If your lower leaves are turning yellow too early, then I would flush and increase the N a little and see what happens.
I had this happen to me this grow. I watered with recharge and did a TDS measurment on going in and runoff to see how much nutes were in there. I did not have lockout and adjusted my nutes up to where she was being fed properly. Found out this lady was hungry! Like CPW said I added more nitrogen and she rebounded great. I also started out feeding her less than what my chart called for. I guess my nutrient companies feed chart with autos in amended soil was spot on . So now I use as directed. lol
my pink autos had an opposite issue of hating the usual feed, too much N got all clawy on me yesterday, switched them to more of a flower stage feed and they are showing recovery this morning and a few new leaves. amazing how flexible these girls can be. even the more sensitive auto's.
