First time grower in need of help with plants

[BudBusters]

So this is my first real grow and all of mt auto flowers were doing great as far as health and once they started to pistil and transition into flower they are all showing similar signs . It started with one plant that went into flower first Turning yellow on the edges going inward then random leafs got a few brown spots . I’m growing in foxfarm soil and it only is happening to plants that are showing pistils

Hungry maybe, lacking N.

I was thinking that maybe at first, but I have auto flowers that are a couple weeks older that aren’t showing pistils yet and they are perfectly fine. It’s the younger ones that went into flower first that are all showing same symptoms

Genetics may be different and plants need different nutrients at different life stages. The fact that only the plants that are flowering are showing the issues, would make even more sense that they are hungry.

Thank youuuuu. Everything was going perfect I even have one auto that’s almost 3 feet tall but as soon as they started showing pistils and going into flower they started to show those symptoms . I’m trying to correct the problem because I’d love to see what this 3 foot purple punch auto will yield

I’m definitely on the same page as you . As far as feeding . I’m nervous to over feed . I have the fox farm trio . What ones do you think I should use . And at how much Ppm . I’m assuming I use tiger bloom now or maybe tiger bloom and grow big combo
