LOOKS LIKE HEAT STRESS OR ...

Magnesium (Mg)
Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.
Magnesium (Mg) deficiency:
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.
Notice how in figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

thanks for the reply weed.. all i have now is dom lime will that work 4 now u think?

I thought it may have been the Tiger Bloom. This stuff is very easy to burn with if mixed too strong. 2 tsp. per gallon however sounds fine, and I have used Tiger Bloom before at this strength with no burning. Perhaps it may be actually be a mag. deficiency.

Also, check your soil pH.

thanks 4 the reply roorman. i thought it was a mag problem too, so i give her a good flushing last night a gave her 2tbs of dom lime maybe that will help...

[fasts102376]

you need I need to speel it right calcium

what can i use for the calcium? can i get it at lowes or the supermarket? if so how much would i use per gallon.... thanks

 

[wall437]

what can u use for the calcium problem? help..

After careful review, I believe it has nothing to do with your ferts. Big Bloom's recommended application is up to 4 tablespoons per gallon, and Tiger Bloom's, 4 teaspoons. You have not exceeded these limits on either one, in fact, you went on the weaker side, which I might add is not a bad idea to start. What you have is presenting a bit like nutrient burn, but is looking more and more like severe Mg deficiency.

1 tablespoon of Epsom Salt per gallon of water, as it says in NDW's growing thread, sounds like it should take care of the Mg problem. I would refer to the link to his thread for more on this.

I would also purchase a soil pH test kit and find out what the pH of the soil is. If the pH of the soil is off, plants cannot access certain nutrients vital to healthy growth and pleantiful budding.
