Advice greatly appreciated ...pure afghan flowering week 4

What's up y'all. Thx in advance for any help or ideas. I love this forum and stay on this shit constantly. Really good knowledge for novice growers. So first off I have a few questions and concerns to run by you .

Im currently in week 4 since I switched the lights to 12/12 and i feel like my growth is slowed. I got these two as well rooted clones from a friend. He's grown this strain for a while and the smoke is by far one of my favorites . Its pure afghani. They were almost a foot tall when I got them so I vegged under some 6500k cfls for 2 and a half more weeks then switched the lights over a month ago yesterday. My cab is really stealth and pretty small 4ft by 2ft by 3 1/2 ft tall. I'm running a 400 watt hps since 12/12 and they are both dwc plants just two five gallon buckets and two air stones and a medium sized air pump. I'm using tap water with a ppm of about 160 and I used botanicare cns17 bloom regular version. Not the shit for coco, at half strength , its done me well in the past , and cal mag at half strength, only using the cal mag on advice from the guy I got these from as he uses it the whole way thru and he always has fantastic results but normally I wouldn't use during blower bc I'm not using R/O water and a couple weeks ago I used a small dose of h2o2 29% peroxide I got from my hydro guy bc the roots looked like they were browning a bit. No smell or sliminess just wanted to try and prevent anything from getting out of hand. My ppms as of last nite were 780 and the temp with the lights on is around 75 and 60 to 65 when they are off. I change the nutes every 7 days and I flushed for two days between veg and flower. . They smell like I could eat them ...amazing but a few of my bottom leaves are yellowing and dying and some of the upper leaves look like they have some sort of deficiency a little yellowing and they just look farther behind than they should from all the pics I've seen of this strain. It's supposedly 8 to 9 week flower time. I know you can't always go by that but just let me know what you guys think and thx again. Keep smokin .........

Here's a couple more pics

Looks like they need a tad more p and k sir. Lookin good though.

Thx for the fast reply man. So if my tap water is 160 ppm and my total ppm is 780 that means I'm only runnin 620 ppm huh. U think I should go up to 900 or 1000 ? I fed em a little much the Saturday before and my ppm was at like 1300 so technically 1140 with my tap water and they seemed to do ok and then I noticed the yellowing so I cranked it down a little this week but I guess I'm still lookin for this strains sweet spot.

Anyone ???

Anyone ?? I looked last night and it seems more of the leaves are yellowing. Starting to stress. I upped my ppms when I topped off my water bc they drank about a gallon. So now my ppms are at 960 including my tap water which I retested last night and they're only about 115. I used about 12ml of the cns17 and a teaspoon and a half of hydroplex per gallon to get more p and k . Added one gallon per plant to top off. Hopefully this helps

Damn no one ?

Bump******

You know your ppms....But do you know your PH?

To a degree. I just ordered a nice ph meter bc my other decided to die . I've been using the GH ph up/down kit with the drops and I wait awhile after I add my mutes and get it yellowish to yellowish orange which is about 5.5 to 6 but who knows ? I hate those drops . New meter should be here by 1st or middle of next week.

i was having problems with my timewrecks fading out too early on me so i waited about 2 weeks into 12/12 before switching to bloom feeding schedule (flora series/calmag/n.u.t.s.and m.o.a.b. for boosters) and they like that much better.

really is amazing the differences in feeding from one strain to the next or even one pheno to the next sometimes.

Here's a pic of them tonite. For going on 5 weeks they look small to me. What u think ? Hope I'm wrong

it is clear from the dark green thick waxy leaves and small buds that they are overfed with nitrogen probably underfed with P-K. what was your NPK at the start of the flowering? I would start flushing them now for a few days just water them thoroughly and let the soil drain its salts then i would feed with high P-K fert with no N like 0-2-5 ratio or close to that

Maybe u didn't read the very first post of mine but they aren't in soil , I have flushed a few times , actually started flushing them last night. I am using dwc hydro and I use botanicare cns17 bloom which is 2-2-5 , a little calmag and a little hydroplex so they shouldn't be very high with N and I would think with the hydroplex 0-10-6 that I wouldn't have a p-k deficiency. I'm so confused . I'm flushing them till tomorrow then I'm done with the cns17. I'm on my way to the hydro store in about an hr when they open to get the GH micro and bloom and I'm gonna run the Lucas formula with that and still add the hydroplex and some floralicious plus for the rest of this grow. . I'm on like day 33 today

sorry didnt catch that, after the flush run it at 700ppm and skip the 0-10-6 use 2-2-5 and dont use cal-mag because cal-mag contains calcium nitrate which is nitrogen too. you have calcium in your hard water and you could use magnesium sulfate (epsom salt) for Mg additive

Ok thx , got a question now . Just got home from the hydro store a few hours ago. I got GH micro and bloom and some hyrozyme and he gave me some humbolt co. Own Ginormous , snowstorm ultra , and crystal burst. I still have some hydrolex left and floralicious plus left I have no idea now if I should use all this shit/ some of this shit or what. I plan on using the Lucas formula for the grow / bloom and using the hygrozyme at full strength and the snowstorm and crystal burst at half strength with 3 drops of floralicious plus per gallon , my only fear is mixing all that shit together and getting a ppm reading of 2000 or somethin crazy and my ph gettin out of whack. We shall see in a few hours when the light turn in and I change the res again. Anyone have any suggestions I would love to hear em. Thx and stay smokin

Ok update, just changed the buckets after a solid days flush and added my nutes. I have 3gal of water in each bucket. I went a little light on everything and still ended up with 1300ppm !! I took some nute water out and added fresh water and let it sit for a bit and rechecked and they're at 1150 , so really a little bit over 1k if u factor in my tap water.




(These #s are total for all 3 gal) I used Gh micro(20ml) and bloom (40ml)Lucas formula ..snowstorm ultra(6ml) , crystal burst (6ml), floralicious plus(6drops) , and hygrozyme (20ml) and 3 tsp Epsom salts. Couldn't get anyone to respond earlier so I just went with my gut and I spent all day reading on here to see what other people did. Hopefully it'll look good tomorrow. Lookin foreword to seeing some comments good or bad. Let me know guys . Thx again. Here's some pics from a little bit ago.

Damn pics are sideways ....sighhh

plants do seem better, you could get ppm lower than that by addnig more water but that's your call, good luck

Cool thx. I would guess that with all the negative things that have happened that they are a few weeks behind. So if that's the case what would a desirable ppm be to you. Thx for your help
