Drooping leaves - Day 10

[Tic tac toke]

Hey guys! I hope you're all staying safe.

To save some typing time, I have set up a thread already in the new growers forum here that indicates my setup for everything - not much has changed in the way of temps/RH and the lights are still at the same height.

So, one of my Quick One's bottom leaves have started to droop and I'm not sure why.

I am on day 10 right now. Days 1-7 I started with pH 6.3 distilled water and no nutes building from 20ml - 120ml/day.

Day 8 I fed them ~350ml of pH 6.2 and ~400 EC to get them started - there was no runoff from this and I didn't want to overwater them so I didn't add more. I noticed yesterday (day 9) that the coco was still moist, so I did not feed them anything and left them to suck up all the feed that was already in the coco.

When the lights turned on earlier today I checked them and they all seemed fine, except for one of my Quick Ones which has drooping bottom leaves. I have given them a feed today of ~250ml each with ~410 EC and pH 6.7 solution as the coco looked to be drying up. The small amount of runoff came out at ~400 EC which was fine, and 8.7pH which is nuts! Not sure why it's so high but I will try and feed them a lower pH solution tomorrow to try and counteract that.

In regards to todays feeding, I know 6.7 pH is too high and I am a little concerned about that - I premixed the solution a couple of days ago and forgot to check the pH today before I fed them and it rose by 0.5! I am hoping this isn't going to be too much of an issue.

My question is - what could be the potential reasons for drooping/have I potentially damaged my plants with the high pH feed today?

Side note: the drooping was present before I added todays feed.

Droopy leaves normally a sign of over watering

I did think this at first!

I have just checked now though (~3 hours after water) and she seems to have perked up! I'm wondering if she was drooping because of underwatering, considering it hadn't had water for ~36 hours?

Yeah it could be that too. Just keep an eye on here befor and after feeds see how shes reacting.

Will do - thanks for your reply!

Can anyone give any guidance on the high pH feed issue? My thoughts are to drop the pH of the solution tomorrow to ~5.8 to see if I can counteract it, but advice is certainly welcome!

@St. Tom I hope you don't mind me pinging you in this post, but I was wondering if you'd be able to weigh in on the pH issue above?

start from tmoz with your ph at 5.8 and feeding every day or 2 till run off and get into the habit of feeding to run off but only feed them again if the pot feels light so to 20 per cent run off the same and just keep going like that and you ec and ph will stay in check also droopy leaves can be overwatering and underwatering from the way you explained it id say you fed her them she perked back and don't worry about checking your run off unless you have issues

Thank you for replying! I will do this
