New grower need help

I have some autoflowers that are in flower but look like there’s some deficiencies going on.

anyone able to help identify what the issue is here?

They need Brawndo. Its got electrolytes.

What nutes and how much have you fed?

I had a two double grapes that grew very similar, the purple stems and all. Luckily, I was able to limp to a somewhat successful harvest.

I chalked it up to them dealing with high temps/magnesium deficiency early on.

I use fox farms ocean forest for soil and I have their big bloom, tiger bloom for nutes. I have used tiger bloom on this plant for one feeding, that’s it

Yeah I’m not sure either. My end date will probably be around the first of the year, so I think I’ll get by. But just curious if this is all something I can avoid in the future by starting off nutes, cal/mag during veg and throughout flowering

you need to swap out a bloom feed for a growth feed, there starved of nitrogen
