1 Month Old mother plants dying

had these mother plants going for about a month now inside of a growlab tent. they are in 4 gallon buckets with sure to grow block inserts (like rockwool but ph neutral). they feed multiple times a day with ph between 5.8-6.1 with house and garden aqua flakes a + b. i just switched them over to floranova grow because it seems easier. but they appear to be dying on me. they were doing great for about 3 weeks, now they appear to be getting worse daily.

temperature in the tent is about 74 and humidity around 50%. i have a fan inside the tent sucking air thru the hood up into the attic. they should be getting a good amount of fresh air.

this is not my first time growing, but this is my first time using the tent and growing mothers. what am i doing wrong? any idea what kinda of deficiency this could be?

Nirogean but if something is working good it is never a good idea to switch to a differant nutrient because the n.p.k ratio will be differant.Cut all of the realy bad damaged leaves off this may sound exsteme but there doing no good.Then flush the plants with water ph the water to the start ph before switching to the new feed and return to the old and tested method.Not realy sure what system you was useing before have you got a doser in the tent that is supplying the nutrients.Tent growing is alot harder than many people think because if it is a good tent then it will not be a breathable materiel.This means that you have to make sure that your plants get plenty of fresh air a fan moveing the plant will also help her get that bit tougher.Also looks like you have had a nutrient flucktuation due to changeing nutrients.Never change a good thing a little more work for a good healthy mother is well worth it.She will produce 1000 of nice clones look after her...............tyke..........................................................................................................................................................

Could be a magnesium deficiency. Check this thread out. https://www.rollitup.org/general-marijuana-growing/1469-marijuana-plant-problems-cures.html It really helps to have the plant and the pics side by side so to speak. Great thread, can figure out just about any issue.

Looks like lock out of N and P and could be a little cal/mag prob in there as well

Dude! Wheres my car? Youve been punked. Looks hungry too me.

thanks guys. i just flushed them all with 10 gallons each of ph'd water and a leaching solution, hopefully that will cure the lock out. i have been wondering myself if that tent is getting enough fresh air in it, i'm going to try and create a new vent. hopefully this works otherwise its 1 month and a bunch of cash down the drain.

I've also heard that some tents give off toxic fumes for plants........might wanna look into that as well
