This nute burn?

So I’m feeding with 3-2-4 formula from botanicare.

It was fertilized mar 9 and then again today. I noticed the leafs after I fertilized.

I’m using about 18ml of the feed per 1 gallon of water.

Was fed March 9. Watered normally on March 16 and then fertilized today on March 21.

Or is this an early sign of a deficiency?

Only seen on bottom leafs. Or could it be a ph balance? I’m just doing tap water. In 5 gallon fabric pots. I wait for the pot to get very light before I water again so I don’t think it’s root problem.

Its not over fed from the looks of it. Whatever issue you're having seems to be an environmental (temps/humidity) issue, or watering issue.

You may need to raise the light a little.

Well my temps are seated at general 22-24. Never had the tent go above 27c.

The leaves get brown and yellow on them. Some times they look so dry that when you touch them they crinkle and fall apart. So have a bit of yellow in tips why I thought nite burn and others had browning in the centre of the leaves. I cut the leafs off to allow better circulation to my plant and betyerblight penetration.

The one thing I have noticed over the last few days is humidity at lights out is 70%. It use to be around 51! I have a clip on fan circulating air. But I guess I need to start running my exhaust 24/7.

I didn’t know humidity issues could cause that browning dried out affect.

Well I’m now starting to see small deformities in the leafs. Like the odd small tear or hole. I scoured the plant for bugs and see nothing. Humidity is now at a constant 30-35% with heat at 24C.

Still seeing some discolouration in the leaves. Upper ones and lower ones. Same issue as the photos.

I’m thinking my ph in my water may have something to do with it. It’s not a full blown issue yet but I don’t want it to get worse. But I get the feeling my ph is at 7.5 when I water and I rather bring it down to about 6.5 for nutrient uptake.

Light has also been raised all the way to the highest it can go as my in-line fan is in the way a bit.

I’m thinking I’m going to invest in a cheap ph meter as my Hanna one broke and rather not spend over $30-$40 for a meter after a $200 blew on me.

Buy cheap and effective litmus paper for pH checks. A meter is ridiculous for this.

I’m pretty sure you live close to me and my tap water is coming out at like 8.6 ph and 500ppm the spring always brings shitty water.

8.6. You gotta be kidding me!!!

No wonder my plant is looking like this. The water is way to basic and it’s not taking up the nutrients from the soil. Jesus. Guess it really is a ph problem.

I’d put money on it being ph related.
