Please help. Leaves yellowing and curling.

I am new to growing and have been having this problem and can not seem to kick it. It only has been appearing on my veg plants. Any and all help is appreciated.

Check your canopy temps and light distance and if okay, then get ready to figure out why you may have a nutrient deficiency or lockout. Knowing what the plant is in and what it has been fed will help, as well as ph and water supply.

Our temps and light distance is all good. The plant is in 3ga buckets of tupur soil. i'm Feeding them jungle juice bloom and micro. 5 ml/gal veg-micro 8ml/gal bud-micro. 10 ml/gal veg-bloom 16 ml/gal bud-bloom. I use a ro system and ive been keeping the pH at 5.8

Do the leave have a plasticy feeling? Donyou feed those nutrients every watering??

First thing would be check runoff tds. Or ppm meter. As well as ph of runoff.

I'm not familiar with tupar soil but ease off those nutrients
I like to find a rich soil which can be cut with perlite to get all my strains through veg with nothing but calmg. Which I didn't see you have either. It is essential for r o Ed water. Nowadays a highly amended organic soil and ditched all my bottles!

Yes it is a plasticy feeling. I couldnt put a word on how it felt earlier but, yes similar to that, a rough texture. Nutes w/calmg skip a day same thing skip a day then just water and calmg. I just checked runoff pH and it was 8.2. Appreciate the help so far. I will def have to try the organic soil. What do you suggest?

Ok here is my guess. Looks like salt buildup has locked out a few nutrients. One of which must be iron. The pale bud sights make me think that. However there is probable plenty of iron in your medium just the wrong ph for uptake by roots.

I use fox farm ocean Forrest cut with 30%perlite.
Or roots organic
Any bagged organic soil mix should be fine. You just want to make sure there is plenty of drainage.

To really look into organics as a way of gardening is a huge undertaking. Follow my blog for more info on my soil.

Also I find in most cases the most cannibus wants to be fed is weekly.

First thing you need to do is flush. Pots size? 2gallojs water for very gallon soil. Then add nutrient at 1/4 strength.

Dies your cal mg have added iron? Some do.

Yes, switch out your soil for next grow, that high ph is a problem.

Okay, i will do just that, then get back to you. The pot sizes are 5ga. The cal mg does not have any added iron. and what should i be running my pH at?
