Default Experienced Growers Opinions Needed!

So I grow TLO style, Veg with a 4 bulb T5 and 200w Sylvania 200w( I know these aren't the special LED's but I just wanted to try them and see what happens. And it's been working surprisingly well!! Dark lush green & fat stems) But lately I've noticed this lime green rim around the fan leafs. At first I thought it was Magnesium Def. but I amend a ton of it into my soil plus I use Tap Water so it has Mag. and Ca. in it (My TDS is just borderline, and 6.5 ph. Sometimes I add a 5 gal bottle of sparkles to bring it down further. Plus I flush using only sparklets which has a TDS of 9) I also thought it could be iron (Fe) def. but A. It's a rare def. and B. The oats I use for fungi food, it has a decent source of iron so I ruled that out. I have boiled down to 1.light burn from to much intense light or 2.A def caused by over watering maybe 3. Nute burn of some sort BUT I only give them ACT tea's every 3 weeks or so and their not strong by any means. I haven't noticed any stunting or anything in their growth but I would like to get rid of it and have them look ALL green and pretty again. Here's pic's of a few different plants, my blue power f2 is the worst right now..... I WOULD LOVE FOR EVERY ONES THOUGHT'S!!! THANK YOU!!!!

I don't claim to be a specialist but from the looks of those real dark green leaves and tip burn, I'm thinking too much N. it almost looks like they were flushed of the hot nutes and started to revert back to normal. Again, this is just my thoughts. I am a hydro grower so YMMV. interested to see some of the pros opinions here.

Default Too many options.:.

Hey socal...

Can your narrow down some more details??

Problem affecting older or newer growth??

How about medium type and brand.

Amendment types and brands.

Bottled and ACT nutrients.

Are you pH'ing and if so with what??

Size of container and volume of water fed. Also schedule. Feed,feed, water or feed, water, water.

Size of veg space and distance from light.

Without knowing these.....

I would go with a toxcity/imbalance that in turn is causing a lockout. Could very well be too much N and not enough K under those lighting conditions. The cal and mag that comes from your tap water is most likely in a non usable plant form. That could very well lock out whatever cal mag that your are attempting to amend with. Over wet soil surely can cause issues but that should be obvious growth deformities not burn/leaf necrosis.

If you are full organic i would advise against using synthetic ph adjusters. Creating a microbe colony that can buffer and sway pH will be much more benficial.

Taking shots in the dark here. Come back with some details and whole plant shots if you could and hopefully we will get you sorted in no time.

All the best

Og...:. Also not a pro...

"amend a ton" leads me to believe this is from being overzealous with the feed. It is a mistake that I have made for sure. I am still thinking too much nitrogen and then stepping off the gas. O G has it right, please give more info so we can try and make the diagnosis as precise as possible.
Temps?!!

Hey Everyone! Thanks for all the opinions, I really appreciate it. I've come to the conclusion it is zinc lock out. I flushed the worst looking plant and the run off was dark brown. So there's the culprit, I'm planning on doing a good flush tmw with pure water. I hardly give them tea's, only if need or just a lite one as a micro inoculate. I didn't do any ph. adjusting to my water, I've never had a problem with my water before. BUT I have been dialing in my own version of The Rev's 2.1 mix and I think that's the issue. This batch I mixed a tiny bit to hot. It works great once their transplanted but after about a month they need a good flush. I know that cannabis loves certain spectrum's (450nm-700nm) but so far this sylvania light is working wonderfully! Thanks again everyone I really appreciate your guys input. It really helps me to get second opinions. I posted this on 3 different forums and I've gotten great feed back from all of them.

O and this symptom started at the top to mid plant height rage and works its way from the rim of the leaf, then inward on the actual leaf. It almost looks like N. or Mag deficiency, But both of those start at the bottom leafs and work its way up. It took a lot of researching to finally diagnose this one problem, usually I can tell within the first day or 2....... I'm to tired to type out how my set up is. It's all based off of The Rev's TLO book. I use just about all the same brands n BS. This method of growing is super easy, it's only mending, and giving water with the occasional tea here and there. Thanks again guy! I'm relieved of a lot of stress since find the answer.... good food for thought, WHEN IN DOUBT FLUSH IT OUT! Keep up the good work!

Peace,

Default Nice solution

Hey socal... Good to hear bud

When in doubt flush it out is a good saying... Unless your underfeeding lol

Typically a flush with 3x the volume of the contained will solve most organic imbalances. If feeding synthetics i would flood with half strength nutes after 2x flush.

So i went and checked out this TLO and the rev guy... Seems to be jumping on this bandwagon of "organic" self sustained growing. I diskike people who hype these methods for profit. Dude basically took soil recipes off icmag and put them in a book. Skunk magazine lead editor.... Lolz

The organic method and especially KNF techiniques do not need to be purchased from some hyped up cannabis grower. You can learn much more about local products/amendments and local sustainability by visiting area farmers,merchants,stores what have you. TLO suggesting to buy foreign amendments and specific products strikes me as slightly off.

Heres an interview which struck this "hate" chord inside of me...

The Rev Chats About His New Book, True Living Organics

Gotta love how he hates corporations and bottled nutes and then tries to turn around cand capitalize of a method that has been around for centuries... Heads up everybody, if your using any other method besides TLO then your weed SUCKS!!!

None of this is directed at you however socal!! I wish you the best in any circumstance. As far as your zinc deficiency if your are absolutely convinced that it was what you have then it is about 300x more likely that you are experiencing an overdose of phosphorous that is causing the zinc/iron to be locked out. Such a rarity to have a serious micro deficiency especially in organics... Deficiency is often misread and is usually caused by lockout bc of too much of a specific MACRO.

Good luck champ

Og
