What deficency??

Hey folks...plants 6 .5 weeks old...pro mix medium...using canna terra vega every 2nd watering, small drop apple vinegar to drop ph...any thoughts or remedies?? Cheers!

do note the spots are not on the recent new growth

which may mean its clearing itself

this leads me to potassium def.(K) perhaps

either way I'd pour 3 times the pot volume

with air temp ph'ed water

allow to drain in dim light or over night

and re feed in the morning at half strength

monitor close

good luck

ps avoid the vinigar

Just a side note vinegar is FANTASTIC for killing broad leaf weeds like blue bell and dandy lions. I would think twice before using it on my plants. Stick with phosphoric acid AKA ph down. It goes really far and is really cheap

Cheers guy

Just flushed with 20ltrs of r/o water with added cal mag and put in corner of room in slightly shaded area...another question folks...even if a plant recovers from a deficency, will it afftect buds in anyway...ie...potency? Taste? Yield?...im new to growing so big learning curve!

Only if it is auto's. Autos are hurt by every single setback, otherwise you are OK up until a few weeks into flowering.

be aware that reverse osmosis removes calmag from water, aswell as all of the metal your plant needs in micro-amounts. Just sayin, tap water is just fine if you control ph.
