Nitrogen tox?

[Tizer108]

Hi guys... I think I’ve run into a nitrogen issue...
Planted the sprouted bean on the 26th April into a pre saturated pot of biobizz light.

First feed with biobizz nutes was on day 6 (when the schedule recommended as had 4 leaves and about 4” tall)
dosed with 1/4 of the recommended dose of root juice, heaven and acti-Vera.
3 feeds of the above have been given, taking it to where we are now.

No grow nutes have been added yet. This is why I’m a bit confused.
But have slight yellowing and clawing occurring..

many thanks

I really don't see a problem with clawing but don't over feed at this point. True nitrogen tox will have multiple lower leaves that are clawed and have brown burnt tips ane if you see this happen just flush with plain ph'd water to clean out excess nutes

Thanks for the reply @namvet25... would you say to carry on watering with nutes 2/3 times per week or give it a week of ph water?
Just abit worried about the slightly yellowing leaves, and don’t want it to get worse

Not quite sure how there could be a nitrogen tox anyways as I’m using biobizz light which isn’t hot at all and have 1/4 the suggested nute dosage

Not N tox', couldn't be right? that interveinal chlorosis is a fairly common symptom, usually it's Mg defc. though.... Start reg. nutes now, as in Grow.... the light soil is nearly devoid of nutrients....
