Thanks Chiceh for answering. Glad to hear I'm not the only one with vascilating pH. I haven't tried the ph down. I've gone through 1.5 gals of white vinegar already, so figured it would cost me an arm and a leg to use the ph down although, I must confess, I didn't check the price. The nutes I have are a couple of years old (chris at SS said shelf life is 5 yrs) and I need to get new bloom, grow, plus (or vits), bushmaster, spray-n-grow and something else I can't think of, so figured if the vinegar worked, I could save a bit there. SS said even with vinegar my pH shouldn't change that much, but cut me off on contacting them before I got any explanation, advice, etc.
My plants are 5 wks old and still only 3", but think maybe it was just too hot inside. Have since opened the doors. The leaves are burnt at tips and edges and some leaves are just gone now which sounds like nute burn I would guess, but my TDS shows below 300 and my water is 88, so it seems it should be too low to burn. My two bigger plants are all yellowish at the bottom but green on top, so I would think that is lack of nitrogen. So......if my TDS is low, and the plants are yellow wouldn't that be low nutes/nitrogen. Since plants are also burned guess that's too hot rather than nute burns?
I took a pic of my 4 poor sickly little girls (I'm hoping) so you can see what you think with what's left of them, boo hoo. They're whats left of my 9 WW seeds too, so I'm especially worried.
My Caddy has 2 exhaust fans. How many does yours have? If I close my doors the temps are from 72ish to 94ish which may be why they fried, although SS said if I could put my hand under the light without getting too hot, they should be okay. Must be my ventilation?
Maybe growing isn't as easy as I thought it SHOULD be and my gardens outside are awesome. Maybe I only have one outdoor green thumb???
Help and thanks for taking the time to read all this!!
