Bud wont fatten up

They will still bulk up. I find it easier to feed until runoff at 30% of the volume in runoff, I'll check and monitor the Ec and Ph to see what the difference is between input and output. I also go Feed then next time water then next time Feed and so on. Every time aiming for 30% runoff.

So after looking at your diary You're using a light mix So; with light mix. You treat it like soil. But treating it like coco as for feeding from the jump Fixes can take a long time. So in future id advise using less. As a toxicity is much harder to fix. As if its low on something you just add the nutrients needed. You can add much easier than you can take away my point been. So you need to give less.. Treating it like soil. 1-2 NPK feeds every 6-10days. Follow up water feeds (these follow up water can be low EC solutions such as cal / mag or an enzyme, root stim or bloom stim You can give these more often without risk. But NPK feeds you need to treat like a fully loaded soil. Less is more and if more is needed it can be given but when too much is given all you can do is completely cut the NPK feeds and just give water or an enzyme to help break down any excess feed. As if there's more feed left & u adding more High EC feed. That'll be ur issue. A lot of new growers (including myself think more nutrients + more light means more bud, when it's the opposite actually) a plant on the edge of not enough nutes makes the plant dig deep into her reserves making energy from within. But when there's too much.. that energy I talked about that pushes the plant isn't there but instead its trying to find a balance but can't because its too much in the pot and it throws it off and you get excess nutes giving u what you had. Rusty leafs, smaller buds as the plant didn't dig deep into energy has their was excess nutes it had to deal with. So, where u are at. 5 weeks in bloom. As you count bloom time when you see stigmata not the time you switch to 12-12. That triggers bloom but its not actually in bloom if that makes sense. 5+ weeks so 35-40 days in flowering. The plant has finished fattening and moved into Ripening. So just focus on giving PK any N needed the plant will dig into its N reserves making it produce more trichomes from having to get it from the plant. This will help produce more resin/trichomes as opposed to keep giving it N when it'll leave its reserves untapped, & not letting the plant push itself. Crop steering

Sadly. They are where they are now pal..(which in hindsight, they look good) If u flushed. You need to fix the issue nutrient wise within a day. So they need to be introduced to a lower EC feed and by doing a flushes and catching run off, if the EC starts getting lower.. they bk feeding. Looks like 2 me you fed too often and not doing routine checks to see their feeding progress and this is excess feeding
