n,p,k

is n,p,k of 2.7/1.3/3.8 ok for growing weed veg stage?

it is ok if those are what are listed on the veg bottle of a hydroponic one part formula. yu see tommy mj like a 10-3-8 for veg. A 3-10-8 for flower. Now disregard that. i was just trying to show you what the ratios generally look like. So you can deduce from your formula that you have a veg bottle. Now, one shud note that hydro companies lots of times put low numbers down because they are rewquired to print the minimum NPK per bottle. So give us a name of the company and we can without doubt tell you if what you got is good or will work. Sometimes you find one part formulations but most are three part. It shud say. I prefer to order gh three part off of ebay. It is a good deal on the best nutes. Also get a ph pen. A 50 dollar one at least.

If you got nothing else run with what you got. It looks good for veg stage at a cursory look.

Yeah sometimes the organic hydro nutes have really low numbers but are great nutes.
What brand as tea was asking

vitalink company called hydrogarden?? any good? yes its a three part bottles veg/bloom/buddy, and allso my wee plants 20days old nw and its been suffening from nut lock dnw mag/cal defi signs, i think the ph was very low for the past 4days cus my ph tester a colour chart and only reads frm 6, till 7, im keeping it at 6,2 but i tink i giv it cholririne piosing bet cus i use my tap warter (unaged) as a phup bluffer as it is hard water!
