Nutrient problem maybe?

First attempt at growing and seem to have run into a little issue i cant figure out. 30 days into flower. Currently all the same strain and fed all the same nutrients at the same time but it looks like some plants are doing better then the others and not sure where to go from here. Currently lost a lot of lower leaves due to yellowing and then drying up and falling off. Fed them what i have posted in the picture last week following instructions, but maybe lacking or added to much?

Have you been feeding regularly or just the one last week you mentioned. Pro mix has no nutrition i know of. Is your nutrient dry or water soluble?

Was fed 4 times total once every 2 weeks since week 4th week in veg. Was looking great going into flower and slowly started yellowing more and more and just fed this week. I see the burnt tips and hoping isnt a lockout or overfed but not exactly sure. Here is some photos of the progress of it looking

Are the nutrients water soluble or dry ammendments. Do you follow a schedule for how much or test the ppm / ec of the feed? Do you ever water to runoff?

I add a scoop to a gallon of water per instructions and water about half gallon each plant every 3-4 days. havent watered to run off because of not wanting to get runoff all over the bottom of tent and also noticed been about 3 days and their pots still have a bit of weight to them so not drinking as much

From my point of view.

It started with a to less N. Then there was no magnesium, which resulted in a lockup.

Hashpants is right. In flower the plant use more N, because of the stretch.

They have a deficient and a lockup. From here I can’t help you, because i am growing living soil (and with living soil, i just would flush)

Epsom salt is fairly cheap btw (for magnesium)

You could flush one plant as a test. Since you have no runoff, it is possible they could be locking out due to nutrient buildup and /or imbalanced food. I suggest you try the worst one . Set it in a tub and water until theres plenty of runoff. Half gallon or so. You can use 1/4 of a scoop of nutrient amd a gram of epsom to a gal of water.Then set it on a towel in the tent for a day to help it dry back. Hopefully it will give you another clue within a day or two.

You should bring some unscented epsom salts for Magnesium and Sulfur which your current nutrient does not have. 1 gram per gallon unscented epsom salts. Good catch @SV2025 .

Will do, ill give it a try and see what happens and give an update in a day or two. Will order some tonight of those nutrients so hopefully will have them soon to add, thanks guys

There seems to be no Calcium in your feed, also. All the N is from Ammoniacal and Urea Nitrogen.

Maybe just order a more balanced flower food for going forward. Calcium, Magnesium, sulfur are all necessary.

Do you have that smaller plant in front of your tent on the same feeding schedule? To me it looks like over feed and possibly salt build up. Since you are not trying to water to runoff you might be getting dry pockets which also can cause weird issues. If possible I would try to water til you get a slight run off not too much but just a bit. Than make sure to fully dry back before water/feeding.

Yeah its the same strain was just about 2 weeks behind being planted then the others

I also got this sample pack from cx Horticulture not to long ago but was going to wait until next grow to use them since i was using that generic blend of nutrients i posted above to see how they did. Do you think i should flush and try adding these in before lights go off in about an hour?

If you find one with Calcium/ magnesium you could add some to a test plant. I cant see ingredients by searching those.

Yeah the hydro base A has both calcium and magnesium, will give it a shot, thanks
