Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Yellow parameter leaves
My lady is turning yellow around the edges of the lower leaves others are dark green. I just did a top dressing less than a week ago I used feather meal kelp meal alfalfa meal and some bat quano. Looking at charts it seems to be a nitrogen deficiency. I know feather meal is slow

Yellowing leaves after first Mainline top. Light stress?
Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!! I have raised light to 23". Am I on the right track here?

Lockout during transition
Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. ✌️ 💚 🌱

Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?
