I just flushed and gave the plants a fresh new rez hopefully she'll pop back soon, I was running the nutes for 2 weeks.thatd be my only guess left, id flush and start with a fresh rez, back off the nutes a little. how long have you been running those nutes?
I'm using the standard 3/2/1, I'm in day 5 flowering atm hoping to catch the problem in time. I was thinking the same deficiencies as you cap, but am unsure cause it does kinda look like MG also. I've been feeding at 1.2 ec, maybe they are just hungry? Lumen shock could be a possibility as they were under dual arc 600 vegging but now are under 750w hps. does the 2/3/1 help w/ stretching? or you think they need more nitrogen at first?Are you using the standard 3-2-1 jacks/cano3/mgso4 grams/ gal ratio?
what week are you in (looks like week 1)? to me it looks like they need a little more N and Ca, not really Mg, maybe some P.
I would run 2-3-1 instead of 3-2-1 through the end of stretch. keep your pH around 6.0.
1.8 EC
How many watts? perhaps they are experiencing some lumen shock?
This is only my humble opinion.
The discoloration and stunted growth seem to be on new growth only, as some of the older leaves look big, lush and healthy. curling down on some of them.Did discoloration start with lower leaves then the middle? Are the tips browning and curling up?Any brown rust spots on leaf margins or tips or between the veins?
These are symptoms of MG def.
I'm under 750w hps flowering 5 days atm. I use that exact same deficiency chart, which of those do you think mine resembles the most? I've been mixing them your way, although I did use the last batch of the other cano3 w/ the coatings, I'll be using the yara liva soon. could that be the issue?You never mentioned how much light you're under? Are you in flower or still in veg?
I'm thinking it looks like this also, but should I be low on P w/ 3/2/1 ratio? what causes that ugly mottling w/ the dark green spine in the middle?Could be Phosphorous deff......leaves turn bluish green. leaf steams and veins turn reddish-purple. leaves curl downward starting with older leaves.
just a guess, something else to check, lol
