So i re filled my water res for my young vegging plants and my PH pen somehow played up even tho i calibrated it prior to using and unknown to me i had accidentally set my res to PH 3.1 left it for a day and a half and now the plants have suffered a big nutrient deficiency and Ec shot up to 1.8(set to 0.6) so I immediately re filled my res and re PHed last night but they don’t seem any perkier yet? How long should this take. Thanks. Pics to follow shortly

honestly, it's going to take some time, a lot of that old growth is toast, but they'll start to fill out again with new growth in a few days. It might look way worse before it gets better. I've done this before, now I tend to double check my ph readings with a test kit, just to be sure I'm within .5 of my target.

I recalibrated the pen and its ph5.6 and i re lowered the nutrient solution so it should all be ok now I’m really hoping they bounce back with constant monitoring. I was going to veg for a little longer so i dont mind waiting a few more weeks. I really will be annoyed with myself if i have to start from seed again. Fingers crossed

Yikes! Correct and no you haven't seen the worst yet. @Rurumo I quit using pens, got tired all the crap that comes with them and calibration being off. I use the Hydrion ph strips that measure in .2 increments and it had a slight learning curve, but I'm off and running now. Love how it's working for me. I learned a new nute line while learning these and it still worked out pretty good.

It's must to get them right before you flip buddy. You can take the time now, or it will be a slower flower process
