first time autoflower grower is this nute burn

[orange wing]

skunk number one

canna coco pro plus
3gal fabric pots
canna a and b canna rhizotonic canna boost
week6 pre flower
hard water 400ppm

i was feeding 1200ppm went to 1400ppm started getting tip burn. should i lower nute strength some one told me to feed 900ppm for now i thought that might be a little low. first pic is worse the one in dark is hardly affected they look a little droopy as lights just came on

Need better pictures, can’t adequately see leaf color and condition in either picture.

@orange wing Welcome to AFN. Diagnostic pictures nee to be taken in Daylight 5000K for accurate color rendering. Just use a Daylight CFL bulb. Let it warm up before taking the pictures.

Your going to get lock-outs from too much calcium with starting water at 400 PPM. Most nutrient lines recommend 100PPM or less for your starting water. Max PPM for autos is 750 PPM not counting your starting water. It will be impossible to keep the nutrient balance with your water.

Can you get a copy of your water report online? I would be interested in seeing the mineral content and the sanitation section.

Be sure to tag me with the water report.

we had a letter not long ago saying they are updating water making it better i no that the ph went up almost 1.0 i done some photoperiod plants about 3 months ago they was perfectley fine its hard for me to get pics as im on ground floor flat to many theives in area

Your water report says ~250 PPM EC In Hanna. What scale are you running? That is still too high but in Coco You can run a little higher than in soil.

that is .504 in millisiemens

Your water report does not list the calcium so we have to guess at ~40% of the EC or 100 PPM Calcium.

If you have access to RO water from the store machines, I would blend in a gallon to 2 gallons of your tap water. Then use the Canna Coco Calculator for your nutrient schedule.

No need to be sorry or feel dumb. Why they have 5 Scales and Two Metric measure for the same object is beyond me.

I constantly verify this information by referring to the chart. It is so easy to read Micro Siemens in place of Milli Siemens or vice versa.

i can see why u thought what 2.4ec that would have been thanks for the help much appreciated
