DLI Daily Light Integral. This is the number you use to know how much to feed and when.
Watch the vid. It should be required basics for growing.

That works. watch the video and you will understand all those numbers and what they are for and what they are telling you.
If your light has a dimmer knob, reduce it by 10%

Big Bloom almost never used in the Veg stage; its for flowering - promotes microbe growth
Grow big is seriously fool proof. Expensive but works great. Can be used in small amounts during Flowering but its mainly used in VEG.

Why the extra cal/mag? Unless the strain calls for it

With promix potting soil, in "breathe-able "containers.


ARe you vegging or flowering?

plants look real dry.

Never add something just because it's on the schedule. Those are suggestions.
Cut them in half right from the start. You probably have an overfeeding issue.
Whens the last time you watered with just water?

 

[biggerbud420]

i am pretty sure it is not a watering issue yes i still have problems but im not exactly a new farmer

i thought you were right on the lights its not over feed they look dry because it was about 3 days ago when i watered with plain ass water and like i always do i wrote it all down in my post on this grow that nobody wants to check out

I don't think its a watering issue. It's lights.
