Looking much better Veterror! Especially the ones in your full system. Nice and perky now.
I googled the nutrients you are using and I understand why you over fed them at first. Also I see it's a complete set of products hence all the additives.
From what I can tell it's basically a 3 part but you use the grow and boost in veg then bloom and boost in flower.
In Veg the standard recommended dose equals an EC of 2.0 which seems very high to me. Would be perfect for heavy feeders like tomatoes though.
If you are using 1/4 strength right now and they look good then doubling that to half strength or an EC of 1.0 might even be pushing it.
Personally I'd recommend not going above an EC of 0.8 just yet. You can always up the dose if they begin to look under fed. They might handle an EC of 1.0 but I'd wait until next week for that just to be on the safe side. From my experience and from what I've researched it's better to slightly under do it than to over do it.
I have two different types of nutrients and I'm finding one brand at an EC of 0.6 is has the same effect as the other at an EC of 0.8.
Keep in mind I don't claim to be an expert nor do I have massive amounts of experience. I'm always refining the easiest way to get the best results.
I recommend making a log with notes and pictures for everything you are doing on a week by week basis. Especially while it's still fresh in your memory.
In a few months or years time if you're raising seedlings again it's easy to forget what worked in the past. You can be much more confident just following your own directions with the products you use until the plants start becoming easy to gauge in full veg mode.
Keep the pics and updates coming!
