Problems with new grow

Pics of my girls, half an hour ago before lights out for there 6 hours of darknes.




Hi guys this is my new growth i discovered i have a large colony of spidermite on my cuttings, they are now 16 days old since i recieved the cuttings and they had spider mite when i got them , I had to remove lots of leaves that where super heavy damaged with spider mite, one leave i removed had about 30 mites on it and double that of eggs, it was all wrinkly at the bottom and turning brown, the plants where a lot bushier than this. and some of the damage to the leaves was also cuased when i wasthed them down with soap and water and isopropyl alchohol to try limit the spidermite before i get some chemical warfare stuff delivered to eradicate the borg, ordered floramite and avid to erradicate them.

Im waitin on my ph meter gettin delievered measuring with simple test looks like ph 5.8 to me, what id like to know do you reckon i also have a defficiency of some sort, or something else going on as well as the spider mite??????????

Thanks in advance

Looks like you might have N deficiency. not sure abt using isopropyl alcohol tho.

I didnt use much of the alcohol about 90% water a dash of washing up liquid and about 10% of the alcohol i use if for cleaning cpu as i fix pcs for a living and ive read elsewhere it helps with spidirmite, from what ive read its used 50/50 i did not have that much. To be honest i think i may have turned the lights on a bit early, causing some leaf burn.

It was two days ago when i treated my babies, I will be cleaning them again with just soap and water tomorrow night just before lights out they are on 18/6 now had them on 24/7 before i discovered the spider mite, didnt notice the yellowing its hard to spot under the hps light.

I did suspect an n defficency myself but im a complete novice been googling cannabis defficiencies for 2 days now lmfao, havnt got a proper meter yet but my test looked a bit too orangy yellow for my liking and i have no ph up just have ph down.

Just ordered £90 quid worth of stuff that i should have got at start of my grow. "ph meter, ec pen, avid, floramite, canna cure, 4x1ltr spray botttles, and calibration stuff for the ph and ec meters. " the quicker it all comes the better before i fuck my grow up .

Ive changed my rez a few times coz i thought my ph wasnt correct according to my ph kit, It always shows the same colour after ive added my nutes and from what i see on the chart its about 5.8, this is i shoud be aiming for, my cheap kit that came with the nft only measures from 6 to 7.6 so probably not ideal for hydro with cannabis.
