Needing some help, slow growth, purple in veg?

Having a recurring problem and trying to figure out the cause. Medium is currently FF Happy Frog, I've previously used ProMix and had the same issue.

First week of veg is good, second colors start changing and growth slows a bit, 3rd color is no good and growth is very slow. Fan leaves appear blueish purpleish, stems are purple, newest growth is light green, fan leaves aren't as big as normal, the bud produced is powerful yet weighs close to nothing, very harry and somewhat loose, yeilded about 0.5/sqft.

This post seems similar, however no PH splotches on mine. The dark fans, but light new growth.

Naturally I thought it was a phos problem, however it begins in early veg, and I can't seem to effect the problem in a positive way.

This time around (FFHF) I've only done tests I haven't messed with anything yet but check my data.
Previously I've tried some test groups, some I changed the PH, some enhanced w a bloom booster, some I tried to leech the ProMix and start over. In general none of that had a positive reaction. So, this time around I changed into FFHF hoping changing into actual soil would fix my issues but alas no.

PH - Slurry test of soil says 6.5, I water at 6.5
Water - I was using RO in the ProMix, switched to Tap and that seemed to slightly help. Currently using bottled Gallons of "Spring Water" (Microfilter, UV, and ) as an attempt to test the source of water potentially. Watering based on when soil is drying.
Nutes - None yet 3rd week of veg, have been using Emerald Harvest
Container - 3 Gal Nursery
Environment - RH 45% - 55% , 69* - 75*
Light - Using Hystorm 2000w LED. Currently 3.5ft from canopy


I decided to test a plant in DWC hoping it might teach me something about my materials but unfortunately its very successful, so now I'm even more confused.
Kinda want to just change to DWC but I hate the sound of the pumps. Bought some CoCo to try out maybe.

Any ideas? Very confused, very frustrated. Miss when this made me happy .

Pics would be a huge help. Kinda sounds like a magnesium deficiency, but the yellowing also makes me think nitrogen.

I wonder if your light is closer to 200w than 2000w.
If so then too far away

Good luck

I was looking at your lights, and I won't say it's a "bad" light, it's a little better than entry level but not much. Your "2000w" light only pulls 401w(per your link). So there is no physical possibility that it can do as they claim and replace a 1400w hps(again, per your link). My 400w light is about 18" above my girls in veg. With you being double that, your gonna get fluffy buds everytime.

Not much happening right now, but keep an eye on this thread
I have seen some major deals Come up on some pretty good lights. Much better than their price, wow!

Full power at 18" in veg?

From the canopy, yes. From the ground or even the top of the planter, no

Damn, I got mine dimmed down to ~100 watts at ~18". I thought a lot of light isn't needed in veg. My plants don't seem to react well, when I turn it up much more than what I have it at.

OK, now you got me wondering... where's my damned measuring tape... nope... maybe here, nope. Damnit! Ok, ha! Got it. Gimme a minute.

OK. That is Island Hulk (Kona Gold x Bruce Banner) on the left. And I was wrong. She's 19" from the light. That auto on the right is 12" from the light.

This one vegged at the same height this is Kona Orange(Kona Gold x 1988 Orange county sativa)

Cold floor?

I am probably overdoing it, but I also run my autos in there. And my clones. And my seedlings.
Also, with my sativas/ sativa leaning hybrids if I let them get tall they'll out grow the tent.

ATM can't, however I'm going to try increasing my CalMag and see if that helps.

This is an interesting idea, I don't think it is but I'm def going to check when everything turns on.




Very much appreciate all the replies!

Going to check my floor temp, add more CalMag, and look into getting my old lights back out.

Do 1 thing at a time, and wait to see if there any improvement, before trying another.
