Calmag deficiency? Epson salt spray on leaves?

Anetxu420started grow question 5 years ago

Is this calmag def or something else going on? I can see a little of bleeding from the veins. Not too bad but seems to be progressing a little bit. I water them ph 6.5 with 2cc of calmag right before it seemed to start. They are on super soil, 3rd week. Just her showing signs

Mine did that right around week 4. Turns out my mix was a little hot. I never saw it progress any further than some wrinkly leaves like you have. Those leaves recovered too.

What to do? Where am I at now actually? I’m lost and slightly discouraged When should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lost

Yellow centre veins fan leaves Yellowing 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?

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

3 week old Skittles plant This is one of my skittles plants I'm growing right now. One of the leaves on her started getting lighter spots near the veins. It is only a little right now but I am wondering if there could be an issue that I could solve before it gets worse.

Veins turning light green on lower leaves One of my plants is getting light green veins on the lower leaves. Is this magnesium deficiency? I can't water currently without risking overwatering, can I just foliar spray BioBizz cal mag to temporarily help recovery? Or is this something else entirely?
