Nutrients Cream Mandarine XL, Biotabs & Coco with COBs

Doesn't Myco help with nutrient transition from soil to roots? I'm thinking more Myco = More nutrients being absorbed = Burnt leaves....... or am I talking bollocks again? [emoji23][emoji23][emoji23][emoji23]

Nah don't think you're talking poop mate! I see your thinking totally, but I think there would have been obvious signs of over feeding before the burn?

Call me a knob, but I still reckon she started munching on the leaves until you added PK.

Doesn't matter anyway mate. I still think leaves are just leaves. The buds are clearly spot on, so you're good to go and no harm done. Boom.

Hmmm loony idea here, but could the leaves be a sign of under feeding PK rather than over feeding? So the plant has been consuming from the leaves?

Or am I a complete lunatic?

this is almost what i thought was happening to me maybe it still is just some good old cannibalization but i dunno

On your tabs Bubba mate? Is it Bubba? One of yours looks to be doing a similar thing maybe. I think it is lack of PK but again I can't be sure. The only time I've seen burn look anything like that is when the hydro boys get silly lol. Can't see its possible to burn anything like that with tabs. I still think its deficient rather than toxic.

I know this is a late observation, but I have been going through tons of biotabs grows to do reasearch for my next grow. Your light issue early on, combined with what looks like a phosphorus deficiency, is IMO, the cause of your issues.
Your friend was correct, too much mychos won't harm plants at all, in fact, it would actually help biodiversity. The lights were way too close, she started to lock out phosphorus early, plus you could see the bleaching in your leaves early as signs the lights were close. The lights probably caused a stress reflex and the plants defense system put in into flower early on and then it wanted the P, but there wasn't enough, so she robbed it from herself.

If you had the lights up higher, like 85cm, she would have thrived. I keep my 60w cobs 85 to 95 cm above seedlings and let them grow into the light. That is also why she was stunted a bit as well.
Biotabs are still a touch new to me, but on the deficiency , and light stuff, I know what I am talking about.

Good luck in your next grow.

I learned a lot from this thread, thanks guys!
