Grow Mediums hi its smerkey trying dwc and led/ cfl for the first time dp thinkdifferent

[smerkey]

Yeah the ppm has been lowering in both Oxygirl and bb. One question the biggest girl in bb wich is on the end a few of its top leafs wich are closest to the light are patchy I think its light burn as the light was a bit low as I forgot to lower it. All the other girls are nice and green. Here's a couple pics wat u reckon mate

Though I'd chime in for once since DWCocha is always handling business It could be burn from the light but imo it looks more like basic signs of underfeed? If your ppm's have been dropping she probably wants a bit more food. Those blemishes looks mostly like calcium deficiency if I had to choose one

Edit: What lights are you running on them now? You could raise them slightly just to diminish the chances of it being a problem. A very basic general rule of thumb is if it's too hot for your hand it's too hot for the plant, but that's mainly for hps I think :Sharing One:

Thanks Pal dude ,you always give solid advise so I'll just confirm your thoughts mate . Underfeed & the start of cal mag deff looks like the prob.

Gearing up for some overfeeding & tip burn on PK week so thats ok ,but the cal mag is on around half strength & can deffo be increased ...

Smerky bro ... get half a liter of water ...add 20ml of cal mag ... stir & dump it in the BB res ... next change we know to add more again :smoke:"AFN smoke out"

Ok bro will do. I've gt them under 300 led and 600 duel spec hps. I have higherd light to correct height now.
