Looks like heat stress and magnesium deficiency.

Maybe try 12/12 next time and dialing back on the nutes.

I have a couple Sun System RA Remote reflectors and the fixture holes match the lamp prongs but the base is recessed into the fixture leaving only glass to grab and twist.

Thanks for the report I think I will buy some new bulbs and contact them about mine that loosened upon installation

Are you using the same mother? Maybe it's getting old.

Thanks for the report I was thinking of using them to determine highest cbd pheno for an upcoming harvest but maybe Ill just do it the old fashion way. I would think they could determine moisture content with the GC/MS and exclude from the results but I don't doubt there are tricks to increase...

Have you checked for propane leaks? Flame burning blue? The co2 should not be making the plants suffer, maybe it's from increased humidity? It doesn't sound right that your co2 monitor is showing 0ppm while exhausting the room.

When I twisted in both my bulbs for first use it caused the bases to have a slight wiggle but they are operating fine.

Sounds it has peat in it and buffered for use as a soil additive. Bagged Canna coco works well for me.

I ordered from JR Peters direct it was a couple bucks cheaper than Amazon even with shipping for the 4# pails. Hoping to do a side by side comparison with Pure Blend Pro and Botanicare additives that I'm using now.

Never got around to building an aeroponic cloner because coco in little cups is working well. This one was 7 days under a dome and 7 days out, ready for a transplant.

Gonna need a better picture of the node area that is more clear. Also they looked stretched, probably need more light.

Are you taking the small cubes out and checking for roots or the bottom of the larger ones? You can leave the cups off and check after 20 minutes to see if they start to wilt. In my experience failed clones start to wilt even under the dome after about a week.

For drinking water and gardening I use the kits from ebay that come with 4 gallon tanks. Sometimes it's a pain to hookup the feed line under a sink and get it to stop leaking. My tap is about 350ppm and after the RO it's 14.

my reflectors didn't have any film either. For the bulb are you putting the prongs in correctly one has a flat spot.

I started a tomato plant in a little styrofoam cup and it grew just like the other random plastic containers.

I've got a couple 315w cmh's and tried to put together something simple. I'm using 5 gallon buckets for res's. 172gph pumps feed a 1/2" single line manifold with 1 open ended 1/4" drip tube per plant that are in 1 gallon pots. Also used a T with a couple valves on the 1/2" tube at the top of the...

If the seeds are older or not stored properly they can take longer to germ and have less vigor. Is your 200 ppm on top of tap water? With coco I'm using RO and starting seeds in around 450 ppm / 0.9 EC which is mostly calmag with some additives and grow nutes. Coco seems to steal the ions away...

They look fine, what light do you have them under? Don't love them to death. :weed:

Do you have the cooling for ~1k of lighting? Also will need to lightproof if running veg and flower in the same area maybe a cheap grow tent will help out there. I'm liking the 315w cmh's so far, you could run 1 for veg and 2 for flower. They do about 3x3 each so you could take up 3x9 and have a...
