Hi guys, this is day 32 and I'm having some issues with this lady:
She's showing interveinal chlorosis in some of the older leaves and also some necrotic spots are developing (red circle in the picture, i had another leave showing this more clearly but couldn't take a nice picture). Also, some of the new leaves have tips culring up, some of them burnt.
I thought this could be Mg deficiency, so I flushed with abundant tap water ( pH~6.8 ) and measured the pH of the runoff with the last pH strip i had, the reading was about 6. I hope this helps solve the problem, if you have any thoughts about this, please let me know.
Looks like a bit of cal and mg deficiency mate, probably caused by the low pH locking out the vital nutes. A pH of 6 is way too low for soil, you want it about 6.5-6.8. Some dolomite lime would help with calcium and to keep the pH up a bit too.
Thanks for the feedback guys! Today I'll go check some experiments at the Plant Physiology lab (not weed related) and I'll have a chance to ask my teacher for some recommendations on solving this issue. I'll keep you updated.
