could this be a possible calcium overdose?

[jdog22]

5th week in flower im still eliminating things it could be, so far ive put lights way higher, temps good, humidity is good, ec was way out at 5700, thats what i get for letting them sit in the water, fixed that with a deep clean and some pingpong balls, ec now at 1000 from run off. my PH has always been good thanks to my nutes PH perfect, though i did check and their at 6.5, literally the last thing i can find was it could possibley be excess calcium. the problem is getting worse because i can figure out whats going on with it.
happy to provide any other details

look a lot like manganese toxicity triggered by heat stress, but you've said temperature is under control ....

some pics under normal light, would help diagnose also.

Need better pictures. Yellow light is making it tough. Looks like bugs but either way probably too late for this run to fix much.

Excess calcium locks out just about everything and makes it difficult to know for sure what's going on. Best bet is to ensure it isn't bugs though first.

You can see too much calcium makes it difficult to uptake everything that connects to the red line.

ill take a few more pictures today once the lights turn on, ill bring one out into normal light.
so there was abit of light stress using 2x 600w hps was pretty hard in a 4x4 tent so ive had to back down to 1000w, yeah the temps havnt given me too much problems im actrully trying to keep temps abit lower than normal, i like what that does xD so there all sitting at 23C during their day peroid and 20C for their night.

im very much thinking they have a overdose off my cal/mag good thing its only a couple weeks from harvest and its only a few fan leaves damaged.
bugs situation ive kept alright with neem oil, only seen a couple gnar nats that i kill off when i find them.

i think from your post i might stop feeding the cal/ag until i see improvement i have money on it that its that! Quick question 1000w of light needs to be fairly far away right? so if im using a 600w and a 400w do i keep them at the same height as a 1x 1000w hps ? or put the 600w where it should be at and the 400w where it should be.today they are in their 6th week. will update when i can take some pictures

gnats larvee cause enough issues, gnats should be taken seriously..
better pics
quickly looks like light stress

The chart is a cluster but it shows all the nutrients that calcium locks out when in excess. K, fe, mg, ZN, P and mn all lock out. Excess calcium locks out almost every other

so how much calcium did you feed?

capt told me in a older post i had my lights too close so i put them up double the height. ill take some more pictures for you nick with a mesurement between lights and tops of plants, i really could had done this so much better im trying really different things and things like this keep poping up haha

i went with pure coco/perlite to help aboid that pesky little gnar nats but your right and i do see 2-3 moving around when i play with the top of the soil checking, ill give the pots a wet down with some neem oil and the tops of the soil after i feed them today. would you suggest any pestacide ? i really thought i took care of them in veg damn little things

 

[jdog22]

at the moment im feeding 2ml in 2.5l of water i use bio deisel cal/mag i put it in with all my feed which i use 3part PH perf nutes and only other sup i feed is monosilicic acid

i don’t use anything, and i controlled a small gnat issue just with the vanilla frosting and harlequin plants, than last 2 weeks i put an end to it..
if there’s no way out other than the surface than you can cover it with a good inch or so of perlite, and i let it go totally dry everytime before watering to kill off some larvee, so controlled it until i decided to end it with same procedure plus adding in another oscillating fan at the same height as top of bags and a 3-5% peroxide mix in spray bottle to lightly spray the perlite on top a few days in a row.. did it for plant stress and hopefully added terpenes..

half hour away, since my first grow all going stressed hermie i put it down to taking pics at night time too often so now im too scared to open the tent during its dark time.

 

[jdog22]

[jdog22]

light burn is one issue

 

[jdog22]

thats the tips hey? the whiteness, capt told me to put them up much higher, they were sitting at 40cm above top colas now they are sitting about 80cm from top of the cola's i found a app on my phone that seems legit its called "photone" can messure the par apprently, but i do have them at 1000par now, which they were at 2500 before lol no wonder they were getting all fkd up :( but with that being worked on, what else do you think could be happening ? it really looks like a calcium overdose but like you said i didnt think i was feeding much cal/mag

good thing is 2-3 more weeks and their done but ive spent so much time on them its sad to see them sad, and i do have a second grow happening so i need to sort this so i dont have the issue 2months from now also i have seen online light burn can increase how bad deficincies and toxicities go on a plant. is that right ?

also im a little worried why my buds smell like fart, i swear i didnt ......

stop feeding nitrogen at this point or the lowest you can.,
what npk ratio are you feeding?

 

[jdog22]

okey ill stop all together, at most in its life i was feeding 8ml grow PH perfect in 2.5L of water, at the moment im feeding 4ml, and was going to stop for her last 2 weeks of finishing up. but if you think its a good idea now, than ill go with that. youre pictures are impressive :) do i keep feeding cal/mag or stop with that also, in the one i use there is nitrogen in it. and mono silicic acid im not very familiar with when is the best time to stop using that ? thanks also for all this advice! means alot
