A little help please

Peat. Ewc. Perlite. About 40 40 20 mix. Have some fish bone kelp alfalfa crab lime mixed in. Week 4 of flower. This just showed up pretty quick. Have had basically no issues until yesterday. Water with natural spring water.. im getting some yellowing on others that seem to be nitrogen deficiency but not sure on this. Mostly on upper part of plant. Thanks

Pic

Pic of the whole plant without lights on will help. Also what size container? Have you been adding any other amendments?

5 gallon pot. I top dressed with fishbone and kelp 3 weeks ago. I know my mix was a little light. I'll get more pics in the morning. This was her a week ago

Barneys farm orange sherbert. She vegged for about 9 weeks and was the runt..

Honestly I think they’re a little hungry. Your plants look great tho btw!

Great looking plants really!!! Looks thirsty but other than that it looks great. As the flowers n buds suck the nitrogen from the leaves they will turn yellow. Happy Growing!!

Thanks guys. I know they are a little short on nitrogen. As they vegged quite a bit longer than I wanted. This is the smallest plant. They all started yellowing a bit these last few days. Going to top dress and water in a little liquid fish also and see what I get.. was really most interested in the first pic of the leaf. I don't think it's bug related. And its only on the one plant. Thanks

Here is another orange sherbert.. shes bigger and a bit of a mess. Already struggling to hold herself up. Think she just wants some more food? Ph in is like 6.8 and I know runoff ph isn't a great indicator but after 20 min its 6.5ish
