Having some new problems..

Hi, This is my First Hydro Grow.. Ive had about 6 very successful Soil harvests..
Right now I'm Running a Sunblaze 480watt T5 setup 8bulb for veg Only..
Rock wool 4in Cubes Then to Slab, 12 Purple Erkle Clones From the Club, 3 Part GH Nutes Using 1-2-3 schedule Some Cal-mag Plus.. Top fed drippers to Waste..
Now My plants are showing Sighs of something I'm not to sure what it is.. I'm thinking its Light Nute Burn maybe? There about 8 days old.. Ill be getting a EC meter on Monday!!..
Like i Said its my First Hydro Grow and i don't really know Whats up so If someone like to give me some Advise id appreciate it..





..

No ones got any Advise?

I wish we new how much fert is in them, i have problems sometimes with clones that size if i give them more than 350 ppm. They look ok but some small amount of nute burn is more than likely the cause.I would try 4 to 6 hours of nothing but ph water then restart my nutes at just under 1/4 strength and see how they like it.But they do look ok. Might be that strain needs more N, i like 3-2-1 for veg, keeps em green.

Algae on Rock wool is Normal..

Hmmmmmmmmmmmm.

After looking at the pics i wasnt sure, but after reading all the post, It's not nute burns it is definitely a Calicium/Magnesium Deficiency. When you use RO water, you need to add some CalMag to your nutrient solution as well.

Those are good choice;
Botanicare CalMag+
SensiCal Mg


You don't want any algea growth on any part of your system. Cover the cubes with B&W.

i was gonna say the same thing. ur calcium is low. I would get Earth Juice Microblast. It has cal, mag, manganese, iron and some other elemental goodness. I've also used 'technaflora magical' but now am going organic.

Just tryin to help you thats all
And definitely not saying this is the cause of your plants conditions LOL its obviously not a algae deficiency LOL

this one is easy to fix, and sorry it wasnt stated earlier(eyes were a little bit heavy that day LOL )

Your plant needs calcium, and it is definitely agreed what some others had said already

yeah, algae is prone to happen often and is somewhat "normal" However, you definitely do not want algae on your rockwool or any other part growing in your system anyways, this will eventually one day lead to bacterial and or fungal infections to your plants root system and then eventually spread upwards if you let it grow out of control. So just keep it in check and you'll be just fine

Enjoy the grow and have fun
