    Default Need some help again

    Just started the 5th week and a new deficiency has popped up on some of the the leafs. At first I thought it was a calcium deficiency but those looked to small of circles and spaced apart. The ones on the leafs are slightly bigger circles bunched together, some are on the top half and some are on the lower half of the leafs. I did have some problems with the pH for the first 2-3 weeks of the plants life, but I fixed it.

    I thought that it has something that has to do with the lights because the ones that were not affected were in the shade of the other leafs. But the top new leafs are all good, also most of the leafs on the plant have tips that are turning yellow. Some of the tips are pointing down and some up, any ideas?

    •Light-150w
    •Soil-Coco coir + Perlite
    •Nutrients-general hydroponics Micro(5-0-1), Gro(2-1-6), Bloom(0-5-4) and Cal-Mag(2-0-0)
    •Humidity-40%-80%
    •Temperature-23-27°c(I don't got the best equipment to keep it right around 25°c, it fluctuates here and there)

    •Feed Schedule- Per Gallon
    Week 1
    Cal-Mag- 2mL
    Micro- 1mL
    Gro- 1mL.
    Bloom- .5mL

    Week 2-4
    Cal-Mag- 2mL
    Micro- 2.6mL
    Gro- 2.5mL
    Bloom- 1mL

    Week 5-6
    Cal-Mag- 2mL
    Micro- 2mL
    Gro- 1mL
    Bloom- 2mL

    •pH-5.5-6.5, but I mostly aim for 5.7-5.9
    I don't have a EC meter at the moment, so I don't know about my water.

    Good morning mate. I have zero experience to tell you what's wrong. But from the very few i know, it looks like a Nutrient deficiency. Isn't it too much to start feeding from week 1 in soil with perlite+calmag? But better count on some other people's opinion.

    I did put that there just to show my feed schedule, but for the first week all I did was water with pH balanced water. Then did my first feed on week 2, thanks for the heads up.

    Why are you using calmag mate?

    Looks like magnesium toxicity. Why are you using bloom in early veg?

    It's a 3 part nute that you alter the amounts on each part throughout the grow (If memory serves me?)
