Hi there, first time growing. White widow autoflower, roughly 6-7 weeks along. Things have been going well since i started, but recently leaves at the bottom of one of the plants are yellowing and wilting. It also looks like the tips of most of the leaves are starting to yellow. I just switched from Fox Farms Grow Big nutrients to Fox Farms Tiger Bloom a little over a week ago. Here are a few pics.
Most things ive read point me toward some either ntrient deficiency or burn, im just inexperienced and not sure. Any advice qould be greatly appreciated. Thanks so much.
I think your plants are looking real good. I have heard that bottom fan leaves will turn yellow. It’s normal. The tips or the leaves are turned from nutrient burn but with just the tips it means you are pushing them to do well. I don’t see anything to worry about.
Happy Growing
Not seeing anything alarming. As the plant matures the mobile nutrients move to where their needed. The lower older fan leaves will die off and you can remove those. Well done they look good
Yup try to stick to those charts, they did a ton of R&D to find what works. I recommend going about half strength until ur sure plants can handle it. But follow the ratios closely and flush on schedule
The couple of lowers yellowing is natural. Just means she was done with those leaves and they dont really help much anyway. I wouldnt pull grow big completely u less the plants show a Nitrogen toxicity or im approaching harvest.
You need to continue the Grow Big along with the Tiger bloom. The grow big has the needed nitrogen and Tiger bloom the PK. You can alternate the big bloom or feed that and calmag on water days
Excellent, thank you all so much. What an amazingly fast and helpful community.
Yeah, i had misunderstood the feeding schedule when i first read through it, it looks like. So, i thought that i wasnt supposed to mix together the nutrients in the same water. And i also though i was supposed to pull Grow Big at flowering.
So ive been alternating one watering with big bloom, then one with grow big . And now, been doing one with big bloom then one with tiger bloom. Whew, big oops here lol.
Just to make sure i got it, i use all 3 nutrients in the same watering each time instead of rotating them and just stick to those ratios, is that right?
Correct. When I use FF nutrients I follow the EC numbers at the top of the schedule rather than trusting those measurements will mix to the proper EC. They never have for me so I mix everything up, check EC and dilute/strengthen as necessary then correct the pH.
I have been watering with the nutrient mix recommended now. Only that one plant is doing it, the other rwo seem okay. I just wanted to make sure that im still okay since the yellow leaves are a bit higher up now.

The picture of the full plant looks healthy. What are the EC and pH going in and at runoff? If those are in range I’d remove the ugly leaves and keep feeding according to the chart.
My two are 5th going on 6th wk veg. Noticed yesterday the yellowing/wilt bottom leaf. Only took a day or two to turn. From this forum guess normal for bottom leaves to give out. Did add foxfarm last night watering. Been watering every 3 days with spray water to get top moist during light/day. Using happy frog soil so the chart helps out the fertilize angle.
thats cool thks for the advice. This morning, before reading this, clipped off very bottom leaves. Today they were more drooped and more yellow. Red line looks a layer above the bottom leaves. Might be cautious and see how they develop before anymore cutting. But yeah, imagine that’s the pruning aspect of getting rid of the wasted energy.
