Grow Mediums Aeroponic,help and suggestions

[Icenitribe]

Hey there autoflower networkers!:tiphat:
This is my first post and basically my first time with autoflowers. First I should say that I'm happy to be here. The strain I'm growing presently is lemon juice express from humboldt seed org. I have this one in an aerogarden and I will be adding a couple cfls when appropriate. I'm using the nutes that came with the aerogarden which are 4-3-6 cal1%mag0.5%sulfur0.5%. My plant is a little over 2 weeks of age and other than it getting a bit of rust on lower leaves it seems happy,I had this same rusting problem with the 2 other lemon juice I grew in soil(they also got horribly stunted and are finishing in the next week). I've been using ph test strips twice a day and lime juice to control. Also what do you guys&gals think about these nutes to buy?

I would go with the general hydroponics setup. Ive run the General Organics in an aeroponic setup and it gets really really messy. And you have to flush out system regularly because there is sediment. I haven't used the technaflora so I don't have any info there. I do know that General Hydroponics will give you proven results and keep your system clean. I have used that in an aero setup and it worked great. Hope this helps..:smokebuds:

Im no expert on def. but I believe she has one. I hope someone with mad diagnostic skills comes and helps!!

Welcome to AFN.. You really need some quality pH and PPM/EC meters for hydro. What's the strips saying for pH? I wouldn't recommend the GO nutes for hydro either.

Thanks mallo,
Yeah I hope someone can diagnose this too...yeah thanks for the nute info I'll probably go with that then...I need to order ASAP.

@jakal, I just checked ph and its at about 6.1-6.3 yeah I'll be ordering a ph pen with my nutes.

 

[mallo]

The general hydroponics kit that you listed comes with ph test solution, which works better than strips in my opinion... but if you can swing it a ppm meter it will really help you nail down your nute regime.

That pH is a little high, shoot for 5.5-5.7 for veg.

Big thanks to both jakal and mallo for responses,I'll get the ph down as for the rusting(it starts on older leaves at tips and moves up the leaf at the edges)...burn or deficiency...or is it a lockout thing with too high ph? This is my first time in a hydro/aeroponic type system so I'm at a learning curve and scraping the wall it seems,but my plant is alive so.

I'm thinking lockout of calcium/mag
