might need a little more N... it looks fairly isolated to a few leaves vs spreading all over in a wave. I wouldn't overreact to it.
in first pic leaf below yellow one is showing something more than N-def. but still limited and not spreading wildly.
it's tough to avoid minor imperfections with that slow release stuff and water-in like gaia green. maybe concentrations don't perfectly spread out? but the ease and convenience can easily outweigh any small issue.
any type of estimates of ppm or concentration of resulting nutrients from labels? while ppm may not relate, the amount of grams added of available N can be calculated and compared to ppm-to-molarity-to-grams of a hydro mix and have a good idea if it truly is low or locked out etc.

Yellow centre veins fan leavesYellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

Top Leaves are becoming yellow from the inside out.Hi, anybody know what the problem is with this plant? The top leaves are becoming yellow/white from the inside out. Also the leaves have a different shape.
The plant is in open soil and I give her water and sometimes some veg nutrients. Thanks in advance. (Last picture)

Slow growth yellow leaf edges what to do?Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.
