Opinions wanted for my clones

Hey

So i have 4 GDP clones in a system and DR 150 tent, my temps are all good.

I used lucas formula and halved the dosage of ml per gallon as it suggested for new plants into the system. my PPM with R.O and all my nutes was about 450

when i bought the clones they had a couple tops of an leafs snipped off and very slight yellow spots on the leafs that were cut , the owner had been giving them nutes in a solution that was close to 1000 ppm.

I noticed this morning the new foliage seems nice and green some of the older fan leaf tips have a spot of yellow right on the tip.

a couple of the smaller leaves of the plant are twisted, not very many and its not the full leaf. just like one or two fingers of a leaf will be slight twisted/turned.


so my symptoms as it stands, some fingers on fan leafs are twisted, bottom showing up. and very small yellow dots on the tips of the bigger older leafs.

possible reasons: im a newb and didnt mix my nutes right at 50 percent ?

My watering schedule is wrong ? i was told to make my pump turn on every 2 hours for 15 mins then every other second hour its on for 30 mins.

To much light to close ?? im running a 400 w air cooled.

My humidity is low , all my temps are spot on except my humidity likes to stay 35 ish very rarely above 40-50


I sprayed some water in the tent to up the humidity and i sprayed the clones with R.O water to increase their humidity

Maybe im not suspose to spray the plants im not sure ! ?




Any help / opinions are welcome !!

I dont do hydro but i think they are over fertilized. twisted leaves and signs of nute burn coming on. like i said i dont do hydro but 1000ppms sounds high for plants (clones) that small. Humidity is too low too but thats not the major issue.
Also you didn't mention your PH? Before you DO anything make sure you have your PH under control.

My ph is yellowish orange so below 6 itsa bit more yellow than i would prolly like it.

The creator of the clones had them at like 800 ppm nute solution when in thier rockwooll, they have been in my aeroponic for 2 and half days right now my ppm went down a bit and its 380 with luas foruma at 50 percent with the gh nutes.

i wish i could help you more. Its definitely a nutrient issue. Its not lighting or temps or anything like that. I do think you should get a more accurate way to test PH. you can get a digital tester for like 20$ on ebay. What ever you do keep a record of it so you can learn from it. Good luck.

I got a question for anyone , My plant has roots on the side and bottom, not loads but some breaking thru the rockwool and going into the hydroton. They are about 4 to 5 inches tall. They have been in my 3 part GH 50 % solution for a little over 3 days. The owner of the clones also said they were being sprayed with nute water.

right now they are in a 50 percent 400 ppm solution , they are 4 or 5 inches tall. Is this to weak ? should i use the full 100 percent veg solution ? or am i doing it right by keeping it at 50 percent ? I dont know when to go full strength on the nutes.
