1st Organic Grow - Should I be Concerned ?

hey guys, have some pics here of various discoloration of leaves, and some missing parts of leaves...Not sure if those missing parts are from cloning way back when, or maybe bugs or diseases ?

anyways medium is pretty simple this run: Pro-mix, perlite, lime, wc, and Epsoma Garden Tone...

I have top dressed with guanos, and kelp....

I've fed her Liquid Seaweed, Floralicious Plus, BioAG Ful-humix, and Maxicrop powder.

Are these normal looking spots ? Or is there something up here ?

She's just about 4 weeks into flowering...Strain is DF Critical Jack.

thnx, SC

Plant looks pretty good overall. What are you using as a water source? Looks more like a toxicity issue rather than a deficiency. I would ditch the bottles and the guano too.

Wow that light configuration makes me shudder. Could of gotten a 3x2 T5 takes up same space with much better light.

Anyways.

She looks like she's developing well. I agree with don, too much of something. A flush and re balance with good flowering NPK should yield best results.

tap water that has been sitting out for over a week.

ph is supposed to be just right for MJ...that's what everyone at all the hydro shop says so

there are two T5's mounted vertically on the back wall....I think it looks a lot worse and crazy than what it is...I've checked all the spec out for the sockets, splitters, etc. and I am not exceeding any limits,,,Nothing is getting hot either....I just added to what I had in my previous grow box - I had half the stuff and knowledge already so I went with it....

Anyways....this is my 3rd grow with this cab...1st grow I had one plant around 600 watts that would have yielded about a half pound if not for mold....2nd grow I was up over 700 watts...2 plants produced well - didn't measure weight though...maybe around 8 oz ?

thanks for your advice....I think I'll keep an eye on her...Those spots are only on a few of the leaves...Most of the plant looks really green and good...What's wrong with any of those bottles ?

maybe I could lay off the liquid seaweed since I have also top dressed with kelp ? Also the Floralicious Plus contains kelp as well....maybe giving her too much kelp ? maybe I should pull back on the kelp stuff for a bit, and just water ? The Ful-humix is just humic and fulvic acids which is supposed to be given at each watering,

it looks like its damage, not an issue with your foods, to me anyways. I think its the fan too close or the light(s) too close.
Keep a journal with organics, especially if you are just starting.. write down all the ingredients, and what happened to your plants, and WHEN. It'll take about three grows to dial it in, maybe more, the key is to make and AGE your mix for at least 2-3 months before planting anything in it. Go LIGHT on the foods and water with AACTs and regular water, I try to avoid ever feeding additional foods if I can, my mix has enough food in it. If I do, I feed lightly, very lightly

all those cfl bulbs create a lot of extra heat, a lot of light being wasted also. You may want to get a better light source, with that amount of wattage, i'd get a 600w hps...personally

thnx for your input grease...I try to keep the bulbs 1" to 2" away....temps have be ok....around 81 for a high I believe....I'll continue to monitor the situation....(I am planning on getting a grow tent in addition to this little project - it will be a 4x4 tent with either a 600w or 1000w HID)

Not really a journal but I am keeping track of the grow in the cfl section...I don't think too many people have this much wattage in cfls, lol....

here's the link to that if anyone is interested:

problem is, those bulbs create light at 360 degrees, so all that lght NOT being pointed at the plant is being wasted, so regardless of the lumens created by the bulb, a good amount is not getting to the plant, not to mention the color of the light degrades fairly fast....and last but not least, that's a whole BUNCH of mercury there, each of those cfls has some inside it, be careful disposing them.

I think one to two inches away is too close, I think you are burning them. Without being there its hard to tell, but my money is on that

"The Ful-humix is just humic and fulvic acids which is supposed to be given at each watering."

^...says the company who cashes in each time your bottle runs out...

This may be your minor problem, although your plant looks pretty healthy, overall). Humics and fulvics increase the bioavailability of nutrients. Even though they have no NPK of their own, they certainly can lead to burning if you're already pushing it.

I'd lay off the humic/fulvic acid for a bit and give them straight water. Your leaves already have a nice deep green color; they can definitely stand to drink some fresh pure water without going deficient right away.

Good luck!

^^^thats good advice. Your pH may be bang on but the ppm may be really high. Looks like early signs of salt build-up in the rhizosphere. Can't really say for sure though.

Alright guys thanks....I'll give her just water for a bit.....

Your trying to grow organic with tap water? You should be using R/O water. You might already have 400-600 ppm in the tap water before you even add supplements.

Soil PH should be 6-7. Typically lower 6 in veg and higher 6 end in flower.

And those little strip lights on the sides look like T4 not T5. (correct me if i'm wrong) Still work; (made a grow box with them before) but same idea as your bulbs. An actual T5 system would be better light spectrum. Then of course the HPS after that.

Yes you can keep plants 2-3 inches away from T5, but the room needs to be cooled properly to take advantage of that. Your temps should not exceed 79F and should range more around 70-75F. 81 is slowing growth and inviting problems.

Don't get discouraged I like your drive and ingenuity. My wow was just expressing a concern for all the energy (from yourself) exhausted on your creative design when it could have been implemented perhaps simpler?
