Can you get some shots of the over all plant? Age of plant?
Heat can cause stress, starching and burning of leaves. My plants are on 100 gal pots in 105 deg weather, with a 60% shade.
If it gets much above that in your green house they will fry..Do you have a temp gauge in there?

What causes deficiency symptoms
The appearance of foliar deficiency symptoms often causes inexperienced growers to conclude that the nutrient solution is deficient in a particular element. However, if a ‘complete’ (see Table 7.20) nutrient formulation is being used, check the following before settling on this conclusion:
- Insufficient EC or feed frequency.
- In recirculating hydroponic systems, the nutrient is discarded too infrequently.
- Inappropriate nutrient pH: Causes certain nutrient elements to become unavailable for uptake.
- Excessive humidity: Hinders the distribution of nutrient throughout the plant.
- Signs of pests or diseases: Their presence can produce symptoms that are similar in appearance to nutrient deficiency symptoms.
