KilgoreTroutstarted grow question 6 years ago
Ok, so I’m starting to see a deficiency. Yellowing between the veins at uppermost leaves. My ph is on par. I’m maintaining my grow per normal with one change. I added Carbo load at 2ml/g.
Could that be the problem?
I think I’m going to flush today and dump my tank. Restart.

Yellowing between veins can be a lot of stuffs bit if you say that it can be spot on the upper leaves then you can be sure it is an immobile nutrients deficiency as the mobile nutrient def is visible on the lower leaves 1st and then spread from the bottom to the top. In you case it can be Iron , manganese or zinc. What is the cause of your trace elements deficiency? I don't know, it can be a straight deficiency which mean you under feeding them a bit or it can be an excess of another nutrient that cause a lockout and made the absorption of the other nutrients difficult. I don't think that carbo load can be responsible for that but you should use a nutrient that contain some trace elements to get rid of your deficiency. Your idea to flush today can be a good solution to reboot the medium 😊👍

Seedling getting too much light?Is my 6cm tall seedling getting too much light? I downloaded a luxmeter app and for front/back cameras, it reads 4000-6000 lux. I'm worried about the light green veins. Is this normal? First grow so super unsure what everything is supposed to look like. Light is 18cm from plant.

Trying to narrow down cause of twisted/incomplete new growth with strange texture and discoloration of lower leaves.2 plants in 0.5L pots in BioBizz AllMix. Using tap water. Both have twisted/incomplete new growth with strange texture and discoloration on some lower leaves. Suspicion: 1. Very soft water-> CalMag deficiency. 2. Low humidity ~25-35%. 3 Need to pot up (planned to do it this week)
