Magnesium def

I grow in ffhf its going on 3 weeks in this soil. Is it time for nutes and cal-mag then. My brand is actually sul-cal-mag, will this be okay?

 

[Gdp1]

Cal mag at least

 

[Gdp1]

Then watch her she will tell u what she needs if not post pics and some out there on RIU will help ya out

Cal mag at least

Okay so I cant find this answer anywhere on here... if im using 1/4 strength 2-2-1 grow solution with distilled water in ffhf should i be feeding everytime? And then as time goes on do i increase beyond recommended dose?

 

[Gdp1]

R u ph ur water

 

[Gdp1]

Not necessarily I feed once a week and water every two days it depends on strain environment and substrate ur using also setting a routine help work out kinks on how often ur plants new food / water

I'm adding updated photos of disease progressing. I added 2ml of sul-cal-mag and 1/4 strength grow nutes to 1/2 gallon of distilled water. Food ph was 5.7 runoff was 5.4. She is bushing like crazy as well and I haven't topped or filmed or anything like that

Also i just noticed fuzzy white mold or fungus growing on the outside of my fabric pots. Is this bad? Never had this happen before

I had the exact same issue!
Calcium deficiency!

up your calcium

Also ensure your not blowing on your leaves too hard...could be wind burn

and lights not too close. You running LED?

I was looking into it and it appears to be potassium deficiency my ph runoff may be off. I will check runoff next watering

Potassium deficiency usually starts on the tips and outside edges and affects the whole leave. You look like you have rust spots that look identical to mine which was calcium.

good luck my friend

Just curious as to y ur ph so low

 

[Gdp1]

Ph should be in 6.5 - 6.8 tops if ur growing in soil

 

[Tokeybear12]

I'm using distilled water with nutes... no ph up or down yet

 

[Gdp1]

????

 

[Gdp1]

Ur feeding should be about 6.5 - 6.8 when tested before feeding

 

[Gdp1]

U should always test before feeding just to make sure ur feeding at right ph
