First Grow with 300W Advanced Platinum LED Grow Light

Glad to hear it. I agree with your decision to up the tds like you described. Your plants are thriving and they're taking in the nutes pretty well right now. I wonder if the brighter light also helps them to grow faster, so that they need more food.
Both vegging and blooming lights have been switched on for full spectrum after the first month so the lights haven't changed for awhile so it's not the LEDs. I dunno, it may be the different flowering Dyna-Grow Bloom nutes.

Dang bro i viewed this whole 14 pages or so and i see nute burn heat stress and they ae still kicking. shows oxygen can keep anything live. the roots are going way unhealthy but yet its gonna flower. i wouldnt expect big dense high yielding nugs. I wanted to scream a few times and yell WTF. here ill post you a pic so you can help your plants grow big fat dense cola's. Just calling as i see it. man i need to rest my eyes now almost made me cry a few times. Im in awe.

Yeah, a lot of newbie mistakes in the learning process, haha. Thanks for the chart, DCobeen.

Oh, I see. I thought maybe you only switched on the red lights when you flipped the daily timer schedule to 12/12. That's what I did. Ok, then I would guess it's mainly because your plants are just healthier now and growing a lot faster than before.

About the root problem, an obvious solution would be to simply put more water in your res so that they're partly submerged as in DWC. Keep using the sprayers on the section of root that's above the water line. I did all my grows basically that way until the previous one. Except I used an ultrasonic fogger to feed the upper roots instead of sprayers. And I put an airstone in the water. Since the fogger didn't really splash the surface of the water a great deal, I guess there was more of a need for an airstone in that setup. It'll mean using more nute, but if PetFlora is right, then it's worth it.

I raised the water level 3 inches so the ladies can drink from the magic elixir better, thanks. I'm still using the sprayers because they agitate the surface so well, 1 on 4 off 45 sec cycles.

Day 10 of flowering. Seeing rapid growth that is engulfing my scrog. Ladies are taking up water and nutes. In flowering the plants are uptaking nutes more rapidly than vegging. I increase strength in stages each time they consume, from 500 to 600, back to 550, increased to 730 backed to 640, up to 750, backed to 575, pushed to 770, backed to 730. Currently at 835 ppm, pH ranging from 5.7 to 5.4 when I add Dyna-Gro Bloom. When do the plants slow their rapid growth and start focusing on flowering buds?

You want your PH from 5.8-6.3 in hydro Edge, looking better bub. You are going to want to get them some calmag, NOT MagPro from Dyna gro (mag/Potash supp), Botinacare CalMag+ works in MODERATION. I think I only applied 1.5ml/gal this round (first weeks of 12/12) You are already at day ten... you need calcium sup within the first week of flower, but you will need it again from week 5-7, just even lighter.

To help keep your canopy even try picnching the stems and "bruising" them, you don't really want to top/fim this far into 12/12, you can, but they wont grow vertically at all after.

Be safe grower!

yes, usually your tap water will have a larger variety of trace minerals, not a "real supplement" of calcium... tap water is fine for full veg, but in my experience (unless just extremely high TDS tap, or lucky minerals in your tap...) you need concentrated supp's of Calcium in flower, among other rest.

It all goes back to read the plants, part of calcium's role is in new growth, when going deficient cannabis yellows from the center out (the new growth),

I believe in tomato's calcium def comes out as Budrot, Lettuce as Yellow "margins..."

I have company over right now, but I have a really good read out of my latest Maximum Yield, I may try and type for you..

Scotch, while I'm ordering my Botinacare CalMag+ are there any other supplements I should get at the same time. Should I get some Advanced Nutirents Big Bud for the flowering cycle or is Dyna-Gro Bloom sufficient? Thanks.

Using paper clips to train my fimmed clones. I have to keep the height of these clones manageable. I think I have about 6-7 weeks left in flowering then I will swap my clones into the flower tent to attempt a perpetual harvest.

Day 19 of flower. Man in flower, every time I try to push my tds over 700 ppm in my aeroponic sprayer system, I get nute burn. Here with 810 ppm. In vegging I would get nute burn above 500 ppm. I added a little Botanicare Cal-mag as per Scotch and diluted to reservoir to bring it down some.

At least you're finding the boundaries of how much nute you can add at different times. Definitely keep notes on this for your next grow. It really seems like aeroponic growing doesn't need a high concentration of nute.

Yeah, Dave.
I think i was pre-conditioned by reading blogs that 800-1500 ppm was the suggest nute targets. However I am finding out that (for these particular strains) 500 ppm in vegging and 700 ppm in flowering is the way to go with my aeroponic sprayer setup. My clones are doing well, green and bushy. I was trying to retard their growth as I still have 6-8 weeks to go with my flowering tent by only using the vegging switch. This past week, I started to add Sensi A & B nutes to 220 ppm and use both vegging and flowering switches in my 150W Advanced Platinum LED clone tent and growth is taking off. This is Day 46 with the clones:

Is it just nute burn or is there any pH flux problems as well? Kinda looks like it but then again never easy to tell problems when there is over fert because it can also cause defs of other ferts. Though I have had good experience with certain strains on aero in the past never getting over say 660 or so.

I check pH every day and it's pretty constant between 5.6-5.7. I had pH fluctuation early in the vegging cycle but no longer. Yeah i have to keep it under 700 ppm and fight the urge to overfeed in the flowering stage.

Flower Day 28. Still messing with some nute burn, diluting my reservoir to bring my tds to 640 ppm from the 775 level. I raised my 300W Advanced Platinum LED 5" to get some better light on the buds around the edges of the canopy and removed some burnt fan leaves. The LED is now 20" from the top of the canopy. Getting some dried up leaves falling uner the canopy.
