HELP ME PLEASE

Hello everyone

Today I found this dots on older leafs . is it mg ? or ph , I'm really confused . please help to identify . and by the way I stopped watering for few days now and the soil is pretty dry . I bought a 20-20-20 cactus fert greengrowth its made in Italy and the best i could find any one tried this before ?

I'm eagerly waiting for replies

Idk probably don't feed till that clears up. I in soil so. Good luck man

My understanding with coco is that it should be trated like hydro & not soil. If you let it dry out it crates an overabundance of K likely causing the issues in your last set of pics. Do you use Reverse Osmosis water or water from tap? If you use RO water, you will need to supplement with cal/mag for the macro nutrients since they are missing in RO water. Tap water doesnt need this since it is usually found to be well fortified with it already. The last set of pics can also look like that due to magnesium deficiency (which is the reason I asked about the water you use).

I used filtered water because we have well water and its so heavy almost not drinkable thats why I filter my water . thanks for useful information . I just bought new fert (it's labeled as micro + amino acids )and will gave it to them and see what will happen . Is it possible that my plant are nut bond ?

Is the leaf near the medium surface,this is normally caused by high humidity.

I have a seedling that popped two days ago in coco she needs to be watered when should i begin ph back to 5.5-6.2? Used tap water ph at 8.0 as it comes out to germ her

I dont run coco so there are certainly more well educated people out there than me on this subject. That being said -I dont believe that coco can be "overwatered" so to say when properly mixed with an oxygenating layer(vermiculite/pebbles/etc). Being such a young sprout, I'd hold off on any nutrients or cal/mag since you are using tap water and just feed ph tap water @ 5.7-6.2 like any basic hyro setup & you should be good to go. Im guessing you would water until you see runoff with coco? Once it gets to about 4-5 nodes maybe then start adding small ppm of N-P-K. She'll let you know what she wants (or dont want) from there. Best of luck!

5.8-6.2 seems to be the consensus on coco. And feed, almost always, very lightly for now. I would say like 150 ppm after the first real leaf set. And probably should charge it with some cal-mag or the like before planting. I just finished my first coco grow, it was decent. I wasn't blown away, I probably didn't nail it, didn't get the crazy rootball I hoped for, but the smoke is more than decent.

That's PH for sure!
Just check it.

Thanks yea i figured raise her ph slightly to figure out what she likes have to look into coco grows a lil more im hoping to flower in a 5 gallon smart pot with coco coir topped with hydroton its supposed to be a hot summer so im trying to keep her roots cool
