Got sick of the leaf tucking and just gave her a trim. It really opened up the lower bud sites. She smelling great and finally got a good dusting of tricomes. I can't seem to pull her out of what I think is a magnesium deficiency. Calmag is about 350 ppm before any nutes are added. Buds are still growing though.
Make a foliar spray with a couple ml more of cal mag than you would for a feeding do that for 5 to 7 days. spray the leaves with cal mag - calmag uptake through leaves is 95%+, uptake through roots is <30% you tell me.
@happyflower,
There is only one way to become predictable in results: constant ambient.
But it's expensive to build and to maintain. Heat pump with rh control and good insulation, either heat exchanger and/or co2 dispenser.
So my approach is to "get the eye" on things, doing mistake after mistake till i get what they will need. It involve a lot of time to observe, keep either mental or photo archive to understand what does what. Doing a lot of training to max the watt result. Doing things that are tunable in an easy and working way. At the end, ambient (fert included) and strain will make different results.
Sometimes tiny, sometimes important. And time of harvest in another factor!
You will have a lot more work to do, but with a really big tasting experience :)
haha, I guess I think unorthodox then. I did take some Calmag solution and tried painting it on some of leaves. I didn't want to spray as the light is on 24 hours and it's a bit on the warm side in the tent. The painting of the leaves didn't make a difference and I took it as the damage was already done. I still have another sour stomper seed so next time it should be better. I was at 5 ml of Calimagic per gallon when feeding this plant and that measured about 400 ppm before any other nutes. My stawberry nuggets was doing the same thing at first until I increased Calmag way over what I was used to. I'm taking away from this grow that mephisto strains are heavy Calmag eaters and you need to overcompensate for it in coco.
@happyflower, I agree with the opinion of someone else, can be some light burn. Obviously light burns are way more pronounced when there is a deficency.
Unfortunatly, without Co2 and the right everything, there is only so much light the leaves can take....
P.S.:
if you see light burn, foliar feed can be a bit dangerous: if water evaporate too quickly, you can end up with salt crystal formations.
I may suggest something more... unorthodox? Just pick a brush and "paint" the leaf steams or the stem that the leaf is connected to.
Always better to start low and then go up step by step to reach the optimal level. Would you prefer to be feed 3 times a day or just 1 big meal forced all at once? ;)
@CRiSPrGrow, yeah, I have that same issue. Next run I will have a tent and be able to adjust the light a lot higher. This 7 week plant is showing same issues as mine but mine are a lot worse with the leaves all cooking up.
@BeefWellingtons, could be lamp to plant distance, if your light isn't perfectly aligned you would be surprised at the difference in coverage and intensity different heights, and places in your tent. check it out a lux meter next time, just go around the room taking readings you tell me. LED 24 inches lamp to plant during veg to avoid over stretching.
