1st grow

@El_Chapo, ok, now I can tell you have a Cal deficiency due to an excessive amount of sodium in the soil , as nutrients build up into salt when they don’t get used after a while. Creating evapotranspirations problems. You must know it takes 3 weeks to use the nutrients in soil. You should follow a Feed Water Water Water Feed W W W F ... schedule and check the amount of ppm’s / mS coming out from the drain with each Watering and readjust next Feeding levels if needed. TDS/EC meter is strongly recommended, more than pH meter.

@JUNGLE_B4RNS, Hmm, how often do I feed them? Good question! Until now I tought that watering = feeding. That means that every time I watered my plants there were always nutrients mixed into the water (so far I only used 6.0 PH, destilled water). "I’m suspecting overfeeding as you’re following manufacturers charts..." Now you got me thinking! Because according to the manufacturers chart it says: add this and that nutrient to your irrigation water. And so I did. Maybe I shouldn't add any nutrients next time I water?! "It would be great if you could know how many ppm / mS ." Unfortunately I don't have a TDS nor EC meter. I am using test stripes to test my tap water (6.5 - 7.5 PH last time I tested. And yes, I know, thats not the best way to do it.).

@El_Chapo,ok, this is for the watering. Sounds good. The problem might come from the feeding, how often do you feed them ? It would be great if you could know how many ppm / mS . I’m suspecting overfeeding as you’re following manufacturers charts ...
