Did a flush yesterday noticed my runoff was leaving really hard water stains I added in cal mag yesterday just not this morning when I watered can always add it in later today just the cal mag no nutes also just noticed this didn’t see it this morning before watering
It could possibly be the start of a Cal-mag issue. Ut it may not so I will tag others…@Myfriendis410, @Covertgrower.
How close are the lights?
I turned them down a little a raised as high as I can thought it could be the light
When you flushed did you measure the TDS of the runoff?
I agree with dosing cal mag.
Thank you @Myfriendis410 Measured this morning both around 700 ppm and 6 pH do you think I should dose with just cal mag and water or just add cal mag to feed
700 ppm and 6.0 PH is just fine. I wanted to make sure your coco was not loaded with salts.
In heavy demand I will usually go on a feed/feed/feed/water cycle with cal mag administered on water days. I don’t know what your feeding schedule looks like.
Im still figuring out feeding schedule been mostly trying to observe the plants and learn what they need. But what you described is basically it. Reason I did the flush was I noticed that my runoff was leaving hard water stains figured the soil was getting high in salt as you said. I’ll just do pH water and cal mag would you recommend the schedule you mentioned for flowering as well or water more in-between feeding
That depends on where the plant is in it’s life cycle and the quality of the light. Don’t feed over 750 (give or take) in veg and 900 at peak flower. Unless of course the plant tells you differently. One of the things to watch and track is waste salt buildup. If you do runoff TDS and record it you will see it trend upwards. When the runoff exceeds your input; flush with something like Florakleen.
Remember that a simple feed/water/feed/water works great and some of our growers feel they see more daily growth on water-only days.
I suggest cal mag with water only as it jumps the TDS up to 500 ppm or so in R/O water: if you used with your other nutes you would play hell keeping to the above TDS max I quoted above.
Later in flower when the plant’s demand for nutes starts to drop, the runoff will tell you this is happening and before any outward visible signs of anything. So; important data.
Yellowish brown spots are cal def.
Brown bronze spots is mag def.
Yellowing inbetween veins is mag def.
Looks like you cought it early though. So yes cal mag needed.
Thank you very much for all the help
