Nutrient deficiency?

FlavourChaser93
FlavourChaser93started grow question 4 years ago
Plants are showing what looks like a nutrient deficiency on the leaves and when doing a run off test I’ve found the PH is around 4.0 yet my mix is PH 7.0 as I’ve been trying to account for the drop. Any advice would be much appreciated

Looks like ph spotting due to the ph too low but it’s hard to tell as it looks like the pic is taken under a hps. You need to flush that plant with at least 3x pot volume with the desired ph level, soil 6.5 ish, coco 5.8 ish. Then measure the last bit of run off and if needed flush again if it’s still not at your desired level. Obviously take them to the bathroom or over a sink. I have had this problem before when not feeding with enough volume to get the necessary 10-30% run off in coco and the ph swung real low. Hope this helps pal and happy growing👍

@gmslave tiene razón. Además, las fotos no son buenas tampoco para poder saber qué le pasa.
