7th grow - King Tut

This will be my 7th grow in the grobo. I went with a photoperiod strain instead of an autoflower for this one as well. This one is a cross between AK-47 and Ruderalis.

DAY 7: Germination (Day 7 /10)

DAY 21: Early Vegetation (Day 11 /14)


DAY 31: Late Vegetation (Day 7 /14)

It’s been a slow start and not much action in general for this one.

The growth up top seems slowed or stunted and some leaves started coming out a bit “rippled” in one or two places like this:

That prompted me to check underneath where I found some brown on the roots:

I haven’t used any great white + root rescue (my equivalent to the “recharge” product) yet so that brown stuff isn’t that. The cal/mag and nutrients dilute into the water quite a bit so I’d be surprised if that much has already managed to accumulate and stain the roots (and just that portion of them) so quickly. I did skip a drain/fill, though, and during that week there was one day that the temps did get a little warm (up to 74.5°F or so) before I had a chance to compensate but I figured that the hydroguard should have taken care of that (unless it had expired, perhaps?). My other plant currently growing had a bit of this brown stuff as well but it doesn’t seem to be slowed down like this one is.

That was also the last of my hydroguard, so I started to use dr marijane (mixed from powder) instead. A couple days after that drain/fill this is what the roots looked like:

There is still a lot of root growth happening though so I’m thinking that it might not be something to worry about or that I’m narrowly avoiding it and should probably rinse them off for good measure. I’m also starting to wonder if perhaps the dr marijane itself (which I just switched to instead of hydroguard) is contributing to the brown color now. The root growth seems to have accelerated since I switched to it.

So, I left it until the next water change and then doubled up on the dr marijane and here it is a day after that drain/fill:

I’m going to mix up some recharge formula and introduce that during the next drain/fill as well as to the cocopod. I wanted to see how things went without it this time and to try introducing it in smaller quantities to determine how little will do the trick.


What cal-mag and nutrients are you using?

The nutes weren’t even used up until the point of that first root pic. Just started using them (usual AN 3 part set) but at less than 1/4 strength and they are clear at that level when mixed with 10L of water (very slight pink color if any). Also switched cal/mag (to AN as well, ran out of #5 bottles) but that was also after the 1st pic was taken.

I think it’s from the temp going up and the hydroguard being a bit old. It does say to use it within 6 months of opening, and this was month 10 for that bottle. This weekend when I drain/fill will give it a quick rinse with distilled water. So far haven’t disturbed the roots any more than those pics.

I’m using my hydroguard that’s probably 10 months old too hopefully it’s okay…lol. It’s been in my cold cellar so :crossed_fingers:lol

DAY 38: Late Vegetation (Day 14 /14)

Going to extend late veg for another week or few on this one.

Have mostly just been leaving her to grow without much intervention.

About time for a trim soon, eh?.. :scissors:

An update on the roots, too:

The only thing I did was up the concentration of Dr Marijane a bit, no cleaning/etc. Haven’t seen roots this white in a while!
