Sure thing doc, i'm making my decision about LED's based on your grow...I'm either gonna go to 600w or a mid to upper range LED panel.

:cool2:

Definitely would be a good idea of what's going on from a guy that was all HPS then went all LED.

Heya DGF,

Glad you ditched the fever, I think that means you may have won the battle.. I bet you have your hands full when your not 100%, looks like you have lots to take care of.

This is your first grow switching over from HID to LED? Will be great to compare your results. It's awesome to come on here and see people growing to their hearts content. This place is awesome, and thumbs up to you for documenting your switch from HID to LED. I have a feeling that half of MP will be awaiting your results.

Yeah fever sucks, but this lingering cold...if it would just get a LITTLE bit better. I think today will be that day :aok: Thanks

Yes, this is first grow, and I have two 4x4 tents doing a full 8-9 week flowering with full LED right now. Everyone should sit and watch the show. I'll give full unbiased thoughts throughout.

:headbang:

 

[zem]

vitamin c and advil always helped me through cold.

I sure am watching your show, or should i say shows

 

[Dr. Green Fang]

Whoa, whoa, whoa! Had to setup for "summer time ventilation mode"!! Went up into my room and it was 93% RH up there!! :rofl: lol!!!!! hahahaha!!

 

[zem]

:holysheep: you've got an oversized dehumidifier for that??

 

[Dr. Green Fang]

Nah, down to 60% already after I caught it. I'm still kinda in "winter mode" and now it's official... change over

I have to do a nute change tonight. Spiked down into the 4's over 24 hours. Going to empty and refill with solution around 850 PPM's. Going to try to feed them exceedingly light compared to how I have been. Hope that sorts it.

 

[zem]

what was the ppm before the res change? i did notice the very dark green on your last pics it's caused by high N. keeping the right N ratio is a challenge in growing anything not just weed, and it's possibly going to be different under LED not sure of that though, but I do know that under lower light conditions, the plant requires much less N and in a vegetable farm, the vegetables can have a N concentration that is not acceptable in the market

Krazie how led lighting reduces the amount of nutrient uptake.. or maybe the sickness got the better of you, and you had a misread? Easy to blame the sickness this one time.. just sayin

I just started my GJ, brix's hydro LED tutorial. Hope you all enjoy the show!

PPM's were between 1250 and 1400. Too high for LED's it seems (Eh PJ? )

lol! Thanks for lookin' out for me, but yeah... it was wacky.

Will stay tuned and compare notes :aok: Grats Brix!!


Ok, update for tonight. After noticing a still crazy spike down, I took that as a sign to reset my system. So, drained out the solution in there, and put back a new nute soup consisting of 875 - 900 PPM's and ph'd to 5.9. I only added 5 gal back, after draining about 7.5, but that's all I wanted to put back tonight. I'm tired. I'll do another 2.5 gal each tomorrow if needed.

Definitely going to attach a res and find a way to cycle this in the space I currently have.

 

[Dr. Green Fang]

Alright, after the PH spiking down over 24 hour period, and rise in PPM's, that was telling me to change my res out. So, I emptied the 4 bins last night (previous update), and added back a more minimal solution at 850 PPM's and 5.9 PH. Everything is holding strong this morning and stuff looks great so far.

Let's see what happens.

[Dr. Green Fang]

Last night, the Cheese and Merlot OG were holding at 5.8 ph still, but the Cinderella 99 bins (both of them) had dropped from my reset of 5.8 down to 4.9. I fully reset the bins, so I'm very confused what they are telling me. PJ, are they telling me that they are STUPID light drinkers and that 850 is too much for them? IF SO, wouldn't I see the tell tale sign of tips starting to lighten (a.k.a "burn") from my solution being strong?! I'm not seeing anything at all. Are you sure of your thought process you mentioned? If PH is dripping fast, too high food and if they are rising fast too low of food? If so, then 850 ppms are too much and they are showing NO burn. I'm so confused right now. I do remember you telling me to expect them to dip still for a couple days, but why did the C99 do so and Cheese / Merlot hold strong?

As I explained it is going to take a few days for your plants to recover. I am not sure what you are adding in now, but if your adding hygrozyme stop. Once a root issue starts it will just make it worse from what I have seen.

Dump food and lower it more as in like 400 or so until you see them eat again.

Yes your plants are telling you they are locked out. Pretty sure I had previously said in my tips thread that one should cut their food by a third from HPS.

Your plants need to use some of that stored up energy in it's main sun leaves.

 

[Dr. Green Fang]

Thanks for everything PJ. Adjusting and will iron things out :aok:

Currently this is what I've been adding to 5gal:

30ml Micro / 60ml bloom = 775 ppm's


Adding - 4ml Hygrozyme / 4ml Liquid Koolbloom / 4ml Pure Blend Tea / 1ml Bloombastic / 10ml Cal-Mag (I think you said don't use this unless I see issues with mag def... I've not seen this, so should probably stop using it. You need to understand I'm trying to reteach myself these processes for LED's. I'm trying to not get "let down" by them, as I'm identifying that I'm the only reason for let down (I believe).

Go 20 micro 40 bloom, drop the rest.

Once plants start to move the PH up, then you can add some food back.

Thanks so much PJ :aok:
