started grow question 4y ago
Hi all. Just a quick one. Do I need to use calmag on every watering using a sf4000. It's my first time using a led. Thanks for any advice. 👍🏻👍🏻

Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Possible overfeeding nutes?
Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

Should I check only EC or PH is also important?
I was told not to check for PH, add the nutes and check the EC, reach the level I want and that's it, is it right? I'm also checking the water coming out of the plants, they have EC 1+ above what I gave them. If I gave 1.5EC then it will have 2.5EC in the water coming out.

Leaves yellowing
These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?
Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.

Nute Deficiency or New Leaves?!
Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Leaf issues. Lockout? Need to Flush??
Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?
