Vick I don't understand why you want to start splitting the A & B parts to your feed.. They are two different parts that together make a balanced feed for you plants.. Who is telling you to split them & just use B?? Certainly no DWC grower anyways.. Coz they're leading you up the garden path bro.. Use A+B together.. Period.
Start your babies in your res @ .8-.9 EC of A+B.. pH 5.6 no higher!! Ok.. If you have a root stimulant put it in at full strength.. Ok
If your gonna use any cal/mg supplement.. Always ALWAYS..dissolve this into your res first before ANYTHING else.. Another reason NOT to be dropping the A part of your feed.. A has the calcium in it.. Plant needs cal Vick.. Especially under LED.. Simple..
:smokebuds:
Talking seedlings that just broke soil. A small bit of B is all they need.
Really they need nothing for the first week at all, but phosphorous will help them establish roots.
0.8 to 0.9 is a bit high for a sprout isn't it?
Could be the different brand of nutrients.
I know GH nutrients I've tried so far pack quite a punch. You really don't need high EC's.
I'd burn the living shit out of my TD's if I ran that.
I generally can't get to .8 for about 3 weeks without showing burn.
The background from my mountain well is 9ppm though. Not sure what your background is, or how you factor it into your feed.
I'm pretty sure RO water at 0.9 EC would fry any auto seedling I've tried.
I usually can't push past 1.1 EC during full flower without leaf curl, or tip burn.
Not trying to lead him down the garden path. (You know I'm FULL Hydro :head: )
Many root tonics are nothing but phosphorous and micros.
Just a little trick with FloraDuo to give them a healthy start.
(I ran nothing but FloraDuo for the last year)
Peace.
