Rule Andrews’s, Soil Unknown, Jack Herer Grow Journal 2018, 1200 Watt LED

These plants are magnesium hogs, and those are signs of the deficiency starting up. Get some calmag+, soon. A foliar spray every couple of days of epsom salt can help while waiting for the supplement to work.

I just watered them yesterday so the soil is still moist, should I wait until they dry out? Also, should I be mixing this with nutes or water alone with calmag?

 

[Emilya Green]

Start with the calmag with your nutes, and definitely wait for them to dry out first. If the problem keeps getting worse, they need more, and start using it on every application of fluid. So while you are waiting for them to dry out properly, it would be a good time to learn how effective a foliar application can be, yes? The burned spots will not ever go away, but you should be able to keep the leaves green around the damage if you halt this now.

I may have missed it but I didnt see anyone confirm that those are indeed Male plants.
Those are Male, I'd get them outa there unless you wish to have seeds.

I would also recommend much larger FABRIC pots at least twice that size for your next grow, you will get a much better root system, have a far larger buffer for small mistakes and not have to worry about overwatering too much.

I do have cal mag, but I have never used it. I don't have epsom salts though so should I do the foliar with the cal mag?
From my understanding, its best to wait until lights off before spraying. I forget where I read this, but I remember an article saying that the first 15 mins the lights go off, is when the leaves start to relax. During this 15 min period, would this be the best time to spray them?

That is indeed the perfect time to foliar, when the stomas are the most open... but actually any time will work.

The advice about lights off is also given because under very strong lights a pool of liquid on the leaves of plants can act like a magnifying glass and burn the leaves... but with a good fan in the room and good air circulation anyway, between the plants and evaporation, the mist on the leaves is not a problem for long enough to be an issue.
Since you have the calmag, I would just apply it at your next watering and see if you can see a reversal of the progression of this thing. If it keeps progressing, give calmag every time, water or water/nutes. If it progresses after that, up the dosage. Foliar with the calmag instead of epsom salt might have some effect, but it will work far better coming in the traditional way through the roots. Foliar is a band-aid... roots are for feeding.

I'm almost certain one of the Jack Herer's are male. He was discarded this morning. The other two in question haven't really changed much more.

Awesome! Thanks for all the info!!!

All of those pics look Male to me

Upon looking closer, I think the last pic's are females too! I'm starting to see a couple pistils!!!

One of the pots was dried right out, so I was able to water with nutes and the cal mag.
My tap water's ph is 7.6 and 165 ppm.

The solution I mixed was 75% strength and full strength cal mag. The ppm going in was 995 and the ph was 6.0.
Usually when I mix just the nutes, the ppm drops to 6.4, but I guess the calmag brought it down a little lower.

I followed the link in your signature about how to water a potted plant and wow, I wish I had seen this a while ago. It makes so much sense.

Question: After the transplanted root ball surfaces, is it ok to leave it exposed?

Roots don't like the light... I think i would throw some more soil or some mulch on top of that... anything but cedar or walnut.

 

[RuleAndrews]

What a difference with the calmag. The one plant that was dry enough to water yesterday, is noticeably perkier than the others. I'll be giving the remaining plants the same in a couple hours.

Added some 2700k T8's for some side lighting and 4 x 23w 3000k CFLs I had hanging around just for extra light. The CFL's are about 6" above the canopy. The plants seem to be growing fast now so I'll have to keep an eye to make sure they don't grow into the lights. Total now is about 750 true watts.

 

[RuleAndrews]

I think the other two plants in question are males. Pretty sure the one is a hermie cause there are pistils along with sacs. That's what the first 4 pictures are.

I think The other Jack Herer is a male too...thats the last two pics.

It's almost night night for them so I'll leave the two in question out of the tent until I know for sure.

 

[Pennywise]

Last pic is male for sure

 

[RuleAndrews]

10 days into flowering - Still have a leaf or two that are curling in and down...Not sure why..

Some progress pic's!

 

[Pennywise]

Is your humidity low, that can cause them to curl down like that.

 

[RuleAndrews]

Sure is. It's almost at 30%. I've got wet towels in there and an aquarium with an under water fan moving the water around. Not sure what else I can do...

 

[Pennywise]

Plants look good but continue trying to get the RH up. I use a 5 gallon bucket with water and a towel hanging with the end in the water. I place a fan to blow across the towel. If you have an extraction fan maybe turn it down a little.

 

[RuleAndrews]

I'm gonna try the towel dipped in my aquarium. The way I have it set up, the towels dry out really fast. Good call!
The extraction fan is up about 50%, i'll turn it down for sure.

Thanks!

 

[Pennywise]

It will make a difference
