First DWC, buds not getting fat enough.

Hi guys, already have posted before showing some problems that I had with my girls at the beginning. Now the plants have 70 days old and compared to my soil grows the buds looks super thin.
I'm working with a 450w (real watts) Growmaster Led (1800w efficiency). 5 gallons buckets, with 6w air pump each bucket. Hesi nutrients, actually working with 1,8 EC because they got nut burn with 2,0. PH in 5,8. Environment temperature 24°C and water temperature 20~21° C. With an air conditioner working at 18°C.( there is like 30~32°C outside my growing room). Good ventilation with air extractor and intractor.
The girls grown vigorously in veg (not taking in count the problems that 2 of the 4 had) and continued growing nice in pre flowering stage, but they didn't seem to get fat enough yet and the buds looks mature.
It seems strange for me that the buds are getting leaves full of resin instead of calyxes and they don't look fat at all...
They are 2 think different from Dutch passion (the 2 at top) and 2 dark devil from sweet seeds.They were supposed to be ready in 10~11 weeks from the first day, maybe I just need to give them more time, I dunno.

I don't really know what I'm doing wrong so any comment or idea is welcome.

Thanks!

do you use so much Nitrogen ? for me they look dark green, and that should not be the case in flower phase, in flower plant needs, P, K, Sulfur and cal mag. im just a noob tho.

New here, but I veg using led, then have hps for flower. Started flower with just led but they were showing signs of deficiency. If have access to hps try that.

Well at the moment of harvest I realized that the first 2 got nitrogen toxicity so, that's why I think.

Also got a decent 120grams per plant, so 480 in total in a 120x120x200cm tent, so it was a medium size harvest, I think it was fair enough for my first try in DWC, but I got lot of experience.

Hi there ,Are you using any pk boosters those stems are very purple that could be a sign of a lack in potassium in bloom (or has been locking out ) and probably could have used a few nips of some pk . perhaps topping off with nutes (unsure if that was the case). to me they look like that other than that i think youve done well..she probably needs more air also in the solution also lower the levels right down in flower for some more resin production and air to the roots. cheers man nice job :)
 
Honestly yes it looks like your nutes had too much of the Nitro going on and not enough PK. I can tell due to the dark green leafs and the purple stems that are not genetic in this case , dark devil has been know to have a tent of dark green but not like this as well.
How often did you change out your nutrients.
Did you change the line up or followed a line up exact as instructed by the bottle or charts.
Did you not add certin nutes thinking it would harm it.
Did you let friends other touch it do nutes for you.
Did you let this go the full 12 weeks or 8 weeks as most do.
How long did you vegetation.

I noticed that leaf stripping is completely a commercial applications in less its strain genetic to strip the leafs , it's not a great thing to do if you defoliation too much but it's good if you do light leaf stripping and trimming in the first 2 weeks of flowering only.
These plants look to bushy and leafy and that's why the suclerk bud sites in the midle bottom and the leaves the fans too are way too much for that plant, they needed to be stripped a bit.
Also did you do flushes at all in between veg and flower and in between pk boosts and did you also keep veg nutes with flower nutes past week 2. That's bad.

Idk man that's my guess.....
12 12 lights should of been gpod... try 14 10 if you like more lights , lights off don't mean buds growing faster , buds growing in the light faster. . Try that... I havent.

Too much N in later flowering for sure.

I've done a lot of DWC in the last 17 years and what really works well for me is to not change nutes until after the stretch. I'll run my veg nute 3-part at around 1.2 EC/600ppm to 1000ppm during veg using a 3-2-1, GMB, ratio adding bits of nutes at that ratio to keep it in my target zone as they eat the ppm down. A week before I want to flip I'll give them about 200ppm more with plenty of the Bloom and a half dose of Big Bud. The when I flip they get more BB to make up a full dose or better then just enough nutes and BB to maintain the ppm I want.

As soon as stretch is done it's time for fresh nutes and a switch to the Lucas Formula feeding. No Grow and twice as much Bloom as Micro so a 0-1-2 ratio. Plus whatever bloom boosters you may be using but half the recommended amount is plenty.

That will limit the N but still give them plenty. If they need a bit more they'll steal it from the older fan leaves and they will begin to yellow which is a good thing. Lets you know that you're not giving too much N which inhibits flowering as is what seems to have been the problem you've just experienced. If a whole lot of leaves start yellowing fast then I'll boost up the Micro as it has most of the micro-nutrients and a lot of N. Some Epsom salts is good for the extra S and Mg too. Sulfur helps with resin production and is the 'secret' ingredient in bud boosters. A tsp/gal is plenty.
