PH meter was wrong

RedEyes34started grow question 6y ago

So I learned my lesson by not checking the calibration of my PH meter. It was off by .6 and I don’t know for how long. The run off of my plants are right at 6.0. Using FFOF soil. Will it bounce back now that I recalibrated my PH meter or do I need to flush all the plants.

How you solve this all depends on the size of your plants and the size pot they are in. If they are in small pots which don’t hold much water I would just water with a ph or 6.7 until the run off is back in range. If it’s in a big pot and big plant do the same as above, if it’s in a big pot but small plant I think I would wait till it needs another feed and feed at a ph of 6.9 but not till run off which should bring your ph in the soil back in range. Reason why I wouldn’t flush a small plant in a big pot as the over watering might cause more problems than the low ph. Apologies for the long reply but just wanted to cover all bases buddy👍

Hydro - 3 strains. What consequences after slight veg overfeeding ? Do they look dark ?I've had technical issues on veg that resulted in a slight overfeeding and now they don't want to feed much (tap water 0.4 + 0.3 nutes), 5 days after 12/12. I'm not sure they will accept very much more, even when I'll introduce flo nutes. Will yield be weak ? And quality ? Thx

Should I Foliar Feed After 2nd Week Flower?I've been toying with the idea of a foliar feed during flower. I normally don't do any foliar feeds after the second week of flower, just to help prevent contamination or buildup of non-medicines in my final product. Any suggestions as to what i should feed my lil purple budling?

Time to Start Flushing Hey guys, I'm writing because I have one mature plant and I'm doubting if it's a good time to start flushing it. Trichomes are starting to look cloudy, but still many are transparent. Do you think it's time to cut off nutrients ? Thanks and happy growing !

mmmlovelytomatoes

any other feeding recommendations?For my next grow I'm gonna do something very similar. I used Canna A+B, with about 8 feeds of PK and a little Cannazym. Does anyone know what else I could use to supplement the feeding, preferably from Canna? My main issue is the tightness of buds, but probs insufficient lighting

Hey guys! I have a question: how do you determine the last 10 days/week of color when you need to switch to ripen? The passport only works in ideal conditions! How do you determine it, by the color of the trichomes, or what? Good luck and happy growing!

Watering too much at once vs runoff?‚Watering when soil is 2,5 cm dry‘:I read the soil should never be ‚swamp‘ wet after watering, yet I also read that the run off needs to be tested regularly - but watering till water runs off does make the soil muddy. Can there be too much water at once if the soil Is dry on top?
