Yellowish new growth, dry leaves, random spots of possible burn in coco hempys (PICS)

Hi Everyone,

One my first run of coco hempy buckets and starting to have a few problems. For a while everthing was going great and now i am noticing some yellowing of new growth. On some plants there is slight curling. The leaves seem to be drying out and there are random spots that look almost like nute burn, but I dont know if thats it or not.

I am using tap water that is about 8.2 ph and about 250 ppm. I didnt know the ppms where this high until last night and i got a digital reader. But have been using ph down, unfortionately i dont think i was taking it low enough (was only using ph dropper kit). Now that i have my meter I am taking ph to 6.1 and with nutes i am at about 1000 ppms i think. Temps run between 70-80 and humidity is usually 50%, sometimes gets up to 60.

For nutes I'm using all technaflora in the following dosages:
Boost 1/2 strength
Grow full strenth
B1 ThriveAlive full strength
Magikal 1/2 strength
sugar daddy 1/2 strength

I really dont have a lot of experience, this will be my 2nd time flowering so any help would be greatly appreciated
Here are some pictures of plants:

bro you need P . pic # 6 says it all. if your in the flowering stage you need to stop useing the grow part of technaflora and use the bloom part and you need to use awesome blossoms. technaflora line for flowering goes like this : BC Boost, BC Bloom, Awesome Blossoms, Thrive Alive B-1 Red, MagiCal, and Sugar Daddy. I use Technaflora myself and have nice results with it, But during flowering i switch the Bloom and Awesome Blossoms to Beastie Bloomz. the plants love it. and the P is high 0-50-30. and at the beginning of flowering dont keep your PPM above 800, gradually jump it up and level it off around 1200-1300. Dont over feed them either its easy to do as you see on some of the other pics you have a slight nute burn. i dont do soil but when i did i always cycled my feeding like this Feed, Water, Water. then just repeat. i also let the top 3 inchs or so of the soil get dry before i feed or water again. Just check it with your finger.

Thanks for the help man! Just wanted to clarify to make sure, I'm not in flower and have been using only the veg nutes at this time. Do you think it could be because i have been going half strength on some of the nutes of does it look like too much fert? On hempy buckets using coco, ur supposed to feed everytime and treat it like hydro from my understanding so thats what i have been doing.

I'm just trying to figure out how it happened. Do you think its possible could be that i didnt use enough calmag, even though my tap water is pretty high ppms @ 250 and maybe ph issue?

Im really just trying to understand, still pretty new at this.

Thanks again!

i dont use what technaflora suggest i use 1/4 to 1/2 . and it most likely happened from a nute lockout. the PH not being right will cause nutes to be locked out and the plant wont use them.

so would you recommend flushing it out and giving it a light feeding or should i give i some nutes that are high in k? maybe some of the bloom nutes? Thanks again

back the PPM down to bout 800 and feed it just a little more P.
