magnesium and zinc deficiency?

[CDNguy420]

Description of Problem:---at first tips of leaves where curling down,now leaves curling up and inward (not jus the tip), from the center of the leaf to the outer ridge(not inluding the stalk parts of the leaf) theres dark dead looking spots some are white(at first looks exactly like spidermites, but isnt ive seen them alot b4 and no its not that) some are rusted colour too.
Length of time problem has been showing:--- day and a halfish..
List any stresses plant has been subjected to:---lmao the fan did fall on it the other night,.. but i couldnt see this happening from that, ive hurt plants outdoors way worse(carreing them to grow space or transplanting, or heavy rains and winds etc)and the problem appeared first anyways..
List the steps have you taken already to correct the problem:---checked the ph and it was at 5.8 going to changed the water in a min, but dont think that is it either..i just changed it 3 days ago, man she drinks alot of water..
Medium: Soil / Hydro (Type/Blend)--- Hydro corn in a deep water culture setup, with an airstone in it..
Light: HPS / MH / CFL / FloroTube / (Watts)--- 1000W hps
Stage: Flower / Vege --just started flowering about a week ago
Stage Age: Weeks: Days: ---not sure was a mother plant about 3-4 months revegged after taking numerous clones, then put into flowering for the last week.
Propagation: Seed / Clone---seed
Avg Temp: Humidity: ---the temp can go from 80-90 degrees F,and the humidity 35-40% when lights off 30% when lights on(cannot help the heat part or the humidity part, but, it never affected the plant b4.. maybe cus its flowering now?
Water Type: Distilled / RO / Tap / Well / City---i usually leave it out for 2 days, but its from the tap,.. so distilled tap water
pH Soil: Water: Additives: ---5.8(water), i use this no name stuff thats 10-52-10 mixed with the original pureblend metabolic grow formula 1.0-0.5-1.0 organic compost,piranha advanced nutrients/carbo load, and i put a couple drops onelast time jus b4 i flowered of superthrive which i know ur not suppose to use when flowering, i only used it for the last watering and only like 3 drops for 3 gal. ive added regular tap water since but the plant has already drank it.
pH Nute Solution: PPM: Additives: i just use whatthey tell me i have 3 gallons of water so i use about 2 tsp of the no name 10-52-10, and then a lil under 1 tsp. per gallon so like 2 and a half tsp. at the most.was going to use mollasses too but not sure how much to add to my mix or when to start adding it?
Last Watering: Avg Watering Frequency & Amount: last water change was about 6 days ago, since then ive added ph adjusted tap water (4L) with no nutes about 2 days ago and its almost gone again so i was gonna jus do another water change...
Last Feeding: Strength: N: P: K: pH: ph is at 5.8 almost always, last feedind was read above..^^
Picture of whole plant. Picture of affected area. Make sure the image posted is under 110KB in size. (600x400 @ 60% quality jpg works)i will post one tonight when i can get a cord to get them off my camera or when i find one around here...my bad

i know alot of u are going to say nute burn but i know what nute burn looks and it starts from the outer edges not the center of the leaves.. like it may be a magnesium def. but i just fed them a week ago and would that show up in a day and a bit?theres no light leaks and its not to close to the light i have it about 2 and a half almost 3 feet away, it gets fresh air daily, no sign of insects(maybe those root bugs but cant see anything, roots looked a lil dark in one spot but its been like that for 2 months and it hasnt gotten any bigger,also new roots grew out, i tried treating the rot by spraying it with the shower head to knock out the rot, and then added a tiny bit of no damp to the water and that was a month ago, so i dont think its root rot considering they are all white except the one spot.. but then again i have no fuckin clue what it could be, id say heat but its been through worse its actually been getting less heat then b4 so i really am stuck.. found the cord so i got pics up now

wow no one? geuss shes gonna die...?

[ALWAYS HI]

I got a similar problem. leaves curling down and turning yellow. only 1 plant. it is the biggest one and it's in a small pot. problem kinda just stared after a few hot days. maybe not started but definitely got worse. i'll try to post pics in about 9-10 hrs. I've been following a pretty good nutrient chart from House & Garden ( the old black one) and check food daily w/ digital tester so I don't think it's a deficiancy.?? Mutliple plants on the same feeding schedule and only one w/ this condition. As I said, it is the biggest plant in a small pot. 2 gal i think.

btw... it's about 3 weeks into flowering. 4 1/2 wks. into 12/12. veged for 3-4 weeks.
i kinda veged it for too long but it was a test anyways.

I have a different plant and every day when the pot dries up, the leaves start to curl long ways. from the sides, up and toward the center. I water and 20 minutes later it's all good.( only 1 week into flowering.)

AWAYS HI

When the leaves cup like that it is heat stress. And at 80-90 degrees there's why. Try to get to 85 degrees or lower and they will stop doing that. They might not "heal" but, no further leaves should taco or canoe like that.

yes but i saw a pic of a magnesium def. and it showed them doing that, i agree the heat would be an issue so thats why im not sure...ive changed my water and used about half the nutes i use only pureblend and some epsom salt, it seems to be getting better but im not sure, it has gotten taller and i seen alot of new root growth so i have my fingers crossed...its about a week and a half into flowering(what a time to have problems).. if it takes 8 weeks to flower do u count the week or so it takes for it to even start budding? as for the guy with the big plant,maybe its root bound?i will update wat my girl is looking like tomoro after i tie her down some more

[CDNguy420]

so here it is took a while to bend and tie them all down, tell me what u think?(for a first indoor grow)

No start the clock after you see buds so 2-4 weeks after going 12/12 start the flower clock.

Magnesium deficiency cases the entire leaf to "pray" up wards not the edges folding over. Howevever magnesium doesn't hurt unless you give too much.

Anyway they look ok
