Tangerine Dream mom - whats going on now?

Potassium lacking again? Its in soil, been getting light nutes at pH 6.5. I just moved it a bit away from the light (T5 though so its not that hot or anything). I actually added a CO2 generating thing a week ago so that shouldn't be bad.

Do soil plants normally need this much potassium? Every few weeks I've been hitting it for a while... every time it seems to grow okay for a second and then develop the deficiency.

I would say she is overdosing and needs a good flush. I would then lighten up on the nutes. I would also turn off the co2 generater as the floresents don't produce enough light for u to gain anything with it running.. flush until runoff is the right ph level and has very little nutes in it for a complete flush. I am guessing your using a soiless premix of some sort?

I repotted using some potting soil from Osh a month or so again. It could be used up at this point though. THe plant was showing some signs of deficiencies earlier (a few times) - never saw any 'burn' on the tips. Flushing and then adding light nutes has worked in he past but I'd like to get it even not have to keep chasing it. Hadn't considered that (re: the T5 not being strong enough to need CO2 additive).

Whole plant pic? Too many nutes is my guess atm. What nutes and pH?
