Possible nutrient burn and/or nutrient deficiency?

• Growing - Indoors
• Watering schedule - every 3/4 days for bigger pot, 2/3 days for smaller pots
• Nutes - Random tomato fertilizer : D (NPK 15-9-12) Was added every second watering for the older plants (3+ weeks)

Yup, over nutriented burning the smaller leaves and the beginnings of nutrient deficiency from nutrient lock. Are there any nutrients already in the soil...as in, is it slow release soil.

No pH measure, cause I don't own any meters right now.

Am I right guessing, that the first and the third pic show advanced nutrient burn (possibly caused by using a fertilizer too soon)?

Not sure about the second one, might be a nutrient deficiency, but I got no idea which one.

I know that the plants look really streched, that's because I didn't have any proper lighting at the beginning. I'll be adding atleast 3 more 20W CFL's soon and buying some proper fertilizers.


Any help would be appreciated : )

Will adding some dolomite lime fix my pH problems? I'm not sure the local shops here sell pH Up/Down liquids, but I'll try to search.

Also, will pH strips work or do I have to buy a proper pH meter?

FLUSH your plants, they are over dosed with food. Use PHed water for the flush. The test strips will work for testing the ph of the water you will use to flush with. The water should have a ph reading of 6.5. May have to run out and buy a couple gallons of distilled to flush with, your plants will love U for it.

The soil is rich and concentrated with npk, stick with just soil and water for now. Since there is already dolomite in the soil mix no need to add more. Luck
