Overwatering or too much light etc?

[TheHighwayman]

Noticed my LSD-25's leaves that are close to the buds are sagging and curving, but it only seems to be a few leaves while others seem fine. I'm not sure what the issue is.
PH: 6 ish (my ph pen is hit or miss with the readings, getting a new one soon)
Nutes: Recently upped the amount to around 500 ppm
Watering: once a week and whenever the pots start to feel really light.

What nutes are you giving her??
not to sure but could be too much N

Been feeding them around 300 ppm of Mega crop but recently started giving 500ppm. Don't notice any major nute burn so it's really weird haha.

temps to hot?

Some leafs are praying while some are down so i don't know, a pro must come in and save the day

What medium is this? If this is regular soil.... are you giving nutes with every watering? If so, I'd cut that out and give a few plain waterings in between feeds. 500ppm is a good amount generally, but it looks like pretty clear nitrogen toxicity. With well balanced nutes like mega crop, assuming you're following the feedchart, any sign of toxicity probably means either (1) you're feeding at too high ppm or (2) you're feeding too frequently. Soil elements like compost or peat will hold onto nutes, so plain waterings in between nutrient applications is a must.

As for pH, if this is soil and you don't trust your ppm pen, 6.5 would be a better target for both nute mixes and plain water.

Long story short, bare minimum no more nutrients until those claws start to settle down. Maybe give an extra watering more frequently too. I'm seeing perlite there and your plant is flowering so it has a good root system and porosity. You're not going to drown those roots if you water more than once per week. Don't be afraid to water. Keep in mind, if you're feeding water soluble fertilizer, the EC/ppm at the root zone will actually rise as the soil dries out. Watering with plain watering more frequently would be a good way to get that soil ppm down (again, assuming this is soil - -this would be bad advice for something like coco)...

Good luck pal!

Thank you, and I have been using mega crop with every watering and my soil is Mother Earth Terracraft Potting Soil. I'll start using plain water in between feedings, thanks again man!

With soluble fertilizers, this my rule of thumb

• with pure coco/perlite, give nutrients every watering
• with peat-based soilless mediums, give nutrients every third watering (feed - water - water, repeat)
• with soil mixes full of "stuff", give nutrients once every 5-10 days depending on strength

This varies depending on loads of circumstances, but might be a good starting point. Soils in general are probably better suited to organic/dry-type fertilizers.

My fertilizing strategy is pretty well based on the tutorial above, and from personal experience, Man O Green is spot on with his data. Great resource for liquid nutes in general.

The soil looks very dry.

On your next watering check the ph and EC/TDS of the runoff. I am willing to bet your soil is rather hot nutrient wise.
