Ok so I have a thread going already and asked the lads that had already helped me again for there advice but i decided to make a new one to see if anyone else can help with my new problem

Ok so I switched to bloom nuts to early and had nitrogen deficiency along with a heatwave, and now all the plant are dying from the bottom up and it’s making it’s way to the main coals and I still have about 4 weeks left… I could cry

Anyone know what’s going on here

I have tried plan ph watering every other feed and done a small flush at one point but I can’t pinpoint what’s going on

I hade a clean up and noticed the buds basically drying up and drying along with the leafs

No idea what’s going on, I have grown for a while now and this has never happened

Could you have been overwatering them? I see lots of roots on the surface. Maybe a root issue. And what soil and nutrients are you using? Is there anything you did different this time besides stopping the grow early, or did you stop giving it N all together?

Time to prune them up, strip all the crap a third up the plant. Make them pretty again. Tops are all your going for in end. The more you get rid of on bottom, the more goes into the tops. I strip to a few buds on tips about 2 weeks in sometimes. Buds stack better and no crap to deal with. Faster transition too imo. Dont cut branches just growth thats never going to be canopy. Those lowers arent going to amount to much, imo. Lots of time to go. Hope this helps, nice tops, btw. Keep what looks like its going to be good. Snip the rest, you can leave the leaves for added energy for plant. Snip skimpybuds off.

Temps during and after heat wave?

During heat wave it hit like 36 maybe more of at times when I wasn’t there to see it, litttally nothing I cold do. I noticed on some things f the smaller plants the the buds dried up then and the hairs turned brown but since the temps dropped back within range of 26/28 the white hairs re appeared and I thought it was coming back to life.. :(
 
Usually when a plant triggers to eat itself it’s stress induced.

Since weed is an annual plant it’s going to die. So usually those stress mechanisms continue until it’s done.

That’s not to say you can’t stop a plant from yellowing it’s just a varying degree of how stressed out it is.

Well they are drinking a lot! But I always Waite until the tops dry and they feel light.. and then water till it’s full then Waite till it dry again.. some times it’s dry by the next day sometimes it takes two.

re used my soul from last grow and using dutch pro a&b multi total and explode sometimes some b52 but I haven’t used that in a while

The roots on top of medium is bc shes root bound, her rootball is like a sponge now. Be very careful not to overwater. Id leave alone until she tells me its watering time. What size pot is she in? Roots do need to dry out, makes plant stronger. Can you uppot without hurting her too bad? Let me know as lve got a few tricks for this. After rereading whole thread my best guess is rootbound still, medium drys out very fast and l believe that is the indicator. If in cloth id repot and leave in pot shes in. Will throw roots through cloth without a problem.

there in fabric 26L pots, so you recon they could all be route bound?It there dry enough I can easily take them out the pots.. will I be able to tell by looking at the bottom of this is the case?
 
God I love my DWC...... and that's what I am going to suggest for you on your next grow. Look into Hempy buckets and forget soil or at the least, look into passive hydro, called Wick method.

You stick a bunch of cotton 1/2 inch rope into the bottom of your pots, the pots sit over a shallow tray, with nutrient water in the tray, and an air pump to keep the water moving and oxygenated. The plants wick the water up to the roots as needed. You can control the amount of water the plant gets a bit by adding or removing rope. Instead of watering the plant, you water the tray... This way you don't over water, and can correct any nutrient problems "on the fly".
 
I'd agree that they're probably root bound and the heatwave compounded the stress they were already under. I had a similar issue with the heatwave here in Ireland, everyone out enjoying the glorious weather and I was cursing it lol I just cleaned up the lower stuff and threw it in with my larf, tops should pull through

that’s the one thing DWC doesn’t like is high temps, so maybe my DWC idea isn’t the best…. Nothing worse than a big ball of root soup…

I would have a look at the roots, just to know, but do figure this is the problem. If are rootbound, break up rootball when uppotting. Will help with shock imo.
