Flowering - Browning and Curling Leaves

[3underpar]

Can someone please provide some advice as to why one of my two plants has browning leaves which are curling up. My other plant is completely healthy and I'm treating them identically.

1) Growing indoors (CFL grow box)
2) Watering schedule - every 2.5 days (fertilizing with organics every 3rd watering - Pura Vida)
3) Growing Medium - soilless
4) What stage of growth - 4 weeks into flowering
5) Checked the soil pH using a test kit. Was ~ 6. Water with 7 pH filtered tap water to bring pH up.

Many thanks.

Hopefully, these are good enough. I can't zoom in more with my camera without getting really blurry. Thanks for any help!

[Quickee]

i cant find anything with what is exactly in it..some products have calcium in them..they expect your soil too..and your going soilless so you may need to get a cal/mag suppliment..botanicare has one i use http://www.gchydro.com/Botanicare+Cal-Mag+Plus%AE.html

Using Technoflora Pura Vida organic according to schedule on bottle. Using a combo of Grow and Bloom, as indicated for aggressive crop growth.

I'll call Technoflora and ask them. It's funny that my other plant shows no problems. Could it be bad genetics, as the plant has always been slow?

yeah i know..i saw it and wrote back right after..i looked the producted up and didnt see what was exactly in it..gave you some info on what to try

 

[Quickee]

what do you mean your plant shows no signs..? mag can effect yield, grow, and other things

OK. Thanks. I'll try to find some.

all you have to do is look at the back of the bottle it will tell you everything thats in your nutes..npk, micronutrients and everything

I haven't noticed any physical problems in my 'good' plant, which was from the same seed set as my problem plant. My good plant may be deficient - I just don't see any obvious signs.

calmag, magical, or epsom salt may help. or a flush and re-watering with a complete micro/macro nute solution.

Thanks. I tried both, actually. I did the flush and re-fert (have 0.5% Mg), but not sure if it's enough Mg. I then watered with dilute Epsom salt solution and spraying the leaves. Should start seeing improvement soon, if not, I still have another nice plant.

Nice grow - BTW.

My plants did this,
im pretty sure its magnesium deficiency

try dissolving EPSOM SALTS in your water or whatever you do

Thanks. I started doing this 4 days ago, and I think my plant is getting healthier.

I'm using Pura Vida aggressive as well. I'm having a similar problem with one of my two plants. It is affecting both plants, but one significantly more than the other. I'm adding ground pelletized limestone now, think if its calcium or mag deficiency or overly acidic soil, them lime will help.

Oh, this is a month old. Did the epsom salts help?
