Please help: Damaged yellow leaves - spreading

Thanks guys, fixed it.

Keep ontop of your ph, it gets tedious but essential. If i had a get looks like a MAG DEF. Try getting some cal/mag, not certain though.

What are you feeding and how much?View attachment 2523800

Yeah definitely a deficiency.

Why are you ph-ing so low? I would stay 6.3-6.5

Did your problems start shortly after you changed the ph? (like within a week or two)

I feed with every water and I water them whenever the coco begins to dry, rather than as a routine. Normally two or three times a week. I was feeding them 5ml per litre of CX ultimate indoor coco growth, I've now dropped that to 2ml per litre. I also add 1ml CX bio balancer, 1ml CX Mighty Grow, 1ml CX Regen-A-Root and 1ml CX Wilt Guard.

When I was feeding them just the fert at 5ml I was using 6.3/6.4 for my PH. The problems slowly began. Now using the new more advanced feed I use 5.8 PH.

This whole PH/Coco ordeal is really confusing me.

Nah they started before. And rapidly hit in 2 days, then I changed my PH down to 5.8 because I read for coco that it is naturally quite high in PH and that it stores salts and such. So you have to use a low PH for coco. I checked the run-off PH out of a pot from my coco. After pouring 5.8 water through the coco, I PHed the run-off and it was 6.3.

I was doing the SAME thing bro. And I had the same effects on my plants(except not as severe because I fixed it quicker. Listen. Flush them! I flushed them with water ph'd to 5.8. Then I began to feed them their regular nutes and always made sure that my ph was 5.8. Also, I supplemented my 5.8 ph nute water with calcium and magnesium. I didnt have the money or really felt like going to the store to buy cal mag so I just added 1 teaspoon of epsom salt to 1 gallon of nutrient water(magnesium) and crushed up 1/4 of 1 antacid(calcium) into a fine power. ph AFTER you add everything. and she should perk up in no time! Goodluck!

dont forget to flush first!

Ah okay cheers bro I'll give that a try. How much PH'd water do I flush through each pot? Double of what the pot holds right?
