Overexposure or nutrient issue? Yellowing leaves

You could have gotten her a little wet but because it is affecting the lower leaves first probably nitrogen deficiency not toxicity. If you have been giving her ample nitrogen then a magnesium deficiency would be the next best bet. To fix it add one tablespoon of epsom salts as a top dress before the next watering cycle. But read a few more answers before making your best educated decision. Happy gardening

Looks to me like some burning from water on the leaves and maybe a bit of a PH issue, Them spots look like calcium to me but could be wrong. I have used Gaia Green for a while and I normally run into N tox with its formula. It works well to mix it up with their power bloom 2-8-4 to help off set the N in their all purpose 4-4-4 50/50 mix is not bad and yields you a 3-6-4 NPK ratio when mixed 50/50, Its still a bit low in K but works well. Can always supplement more K with a seaweed extract or something. I also don't get to many issues in veg, but do run into some problems in bloom, so I don't think it should be having any issues right now. Mixing it into the topsoil can damage some of the roots so be gentile when you doing it. Be aware of their topdressing recommendations or soil amending guides. It's around 1-2tbsp/15-30ml per 1Gal/4L of medium used. Over all its a nice start to feeding the plants and I am moving more along the lines of switching to a liquid fertilizer when transitioning into bloom. I could use the bloom stuff in a bubbleing compost tea type thing but just a lot of work when other products exist for about the same amount of money and less space/time invested.

Hi es gibt 2 Ursachen wo ich sagen würde das es daran liegen kann. 1 wenn du immer noch wie auf den Fotos zu sehen ist Wasser auf die Blätter machst könnte es Verbrennungen sein. 2 wenn du dies aber nicht mehr machst würde ich stark nach einem CalMag Problem tippen. Denn bei einem pH-Wert von 7 kann die Aufnahme von Calcium und Magnesium durch die Pflanzen beeinträchtigt sein, da diese Nährstoffe in leicht sauren Bedingungen (pH 6.0–6.5) besser verfügbar sind. Der Falsche PH wert führt auch zur Blockade von anderen Nährstoffe und du bekommst immer mehr Probleme. Also passe den PH wert, kein Wasser mehr auf die Blätter und füge etwas CalMag zu deinem Düngeplan. Viel Erfolg :)

Slight burning from excessive nitrogen content in the soil. Also, try and keep the leaves dry, there is no need to spritz the leaves...........wet leaves can lead to diseases. Liquid, cannabis specific fertilizers are much better and easier to control than any dry amendmant. Unfortunately, I have seen far too many negative issues in this forum with the product you have chosen.

Leaf's surface temperature directly changes depending on its transpiration rate, with higher transpiration rates leading to a cooler leaf surface temperature because the process of water evaporating from the leaf absorbs heat energy, effectively cooling it down; conversely, when transpiration is low, the leaf can become significantly warmer than the surrounding air. Based on a 3-degree F difference in ambient and LST. 1.44kPa. @80-50% Drop 2F and raise 5% will give you 1.18kPa.

I'm far from a professional... if this in veg, and your recording environment readings of 80F at 50% RH... that's a very high VPD reading of about 1.8kPa. You should be at about 1.2kPa max and this can be achieved be either lowering your temperature, or raising your humidity (I say raise the humidity). At the current vpd, your plants are sucking up more water and nutrients than they can handle it healthy fashion. You are stressing the plants and what you're seeing in the leaves could actually be nutrient burn.

Ph 7 way to high..
